How to change memory configuration after creating sample from MUCXpresso SDK? I know that when creating the sample from MCUXpresso SDK, we can config memory. But I created the sample, I changed many files in this sample and now I want to change memory configuration for my sample (I could not create new the sample, set memory and change files again because the number of changed files is very large). Whether I can config memory configuration after creating the sample and how? Thank you. I found this method Right click to project => Properties → C/C++ Build → MCU settings. Is that correct? Re: How to change memory configuration after creating sample from MUCXpresso SDK? Hi @nnxxpp , Thanks for your interest in NXP MIMXRT series! Yes, the memory configuration can be changed after the SDK example has been created. There is no need to recreate the project. And you may refer to this post: https://community.nxp.com/t5/MCUXpresso-General/MCUXpresso-Memory-map/m-p/1062500   After updating the Memory Configuration, please clean and rebuild the project, and verify the generated linker script and map file. This applies when the project uses MCUXpresso managed linker scripts. If a custom .ld file is used, please modify that linker script directly.  In addition, I’d like to mention the image view window provided by the IDE, which allows you to easily check whether the layout of the generated image meets your requirements: Best regards, Gavin Re: How to change memory configuration after creating sample from MUCXpresso SDK? @Gavin_Jia  Yes. Thank you, now I could config memory without recreating project.

iMX 937处理器的最小和最大睡眠电流（毫安）是多少？   我的项目中使用的是 i.MX937 处理器，i.MX937 处理器的典型睡眠电流（mA）是多少？   Re: What is the min to max sleep current mA for the iMX 937 processor 有了这些维持正常运转所需的资源， 150 µA 的睡眠电流对于 i.MX 937 / i.MX 93 处理器本身来说并不现实。 。 为什么： 模式 电流/功率影响 适合 150 µA？ 功能性贴合 BBSM/RTC模式 数据表列表 1.8V 时功率为 0.14 mW 功率测量应用程序说明显示大约 总计 97.978 µW 仅  NVCC_BBSM_1P8  积极的。 就力量而言，是的。 不 — 只有 BBSM/RTC 逻辑保持通电；GPIO 唤醒关闭，定时器/PWM/ADC 不可用。 暂停 数据表列表 典型值 15.1 mW 在 25 °C 下。 不 远高于 150 µA 等效电流 无/有限 — 暂停会关闭时钟，Cortex-A55 掉电，并使可以关闭的内部逻辑/模拟模块掉电。 Linux 挂起 + M33 在 WFI 中 应用笔记列表 122.4 毫瓦 此用例的总计。 无 建筑风格上更接近了，但仍然远远高于你目前的目标。 低功耗运行/使用Cortex-M33的AONMIX AONMIX 可以在其他功能域断电时运行，并且包含定时器/PWM 和定时器资源。 未记录显示符合 150 µA 标准 如果外设必须保持活动状态，则这是相关的 i.MX 93 模式类别，但它不是 150 µA 级模式。   150 µA 的预算仅相当于 1.8V 时功率为 0.27 mW 或者 3.3V 时功率为 0.495 mW 。那与i.MX 93的性能范围相符。 仅限 BBSM/RTC 状态，不是具有活动定时器输出、ADC、PWM、RTC 和 GPIO 的状态。 推荐架构：保留 i.MX 937 BBSM/RTC 或完全断电睡眠 并将始终开启的功能（定时器输出、ADC 监控、PWM 和 GPIO 监控）移至超低功耗的配套 MCU 或模拟/RTC 电路。当满足特定条件时，配套设备可以唤醒 i.MX 937。 i.MX 937 只能在非常有限的 RTC/BBSM 模式下满足 ~150 µA 的电流；在该电流预算内，它无法保持定时器/PWM/ADC/GPIO 功能处于活动状态。 Re: What is the min to max sleep current mA for the iMX 937 processor 我们的应用程序在低功耗/睡眠模式下需要以下资源才能保持正常运行： 1. 定时器输出引脚 1个ADC输入 1 PWM RTC 2-3 个 GPIO 我们对睡眠电流的要求是 150 µA。 Re: What is the min to max sleep current mA for the iMX 937 processor 对于 i.MX 937 / i.MX 93 处理器本身，数据手册没有给出任何以毫安 (mA) 为单位的“睡眠电流”。它规定 SUSPEND 模式总功率在25°C时为 15.1 mW ，并指出该数值取决于使用情况。挂起是功耗最低的模式，时钟关闭，不必要的电源关闭，可关断电源的 SoC 部分被关断，Cortex-A55 完全关断电源，DRAM 处于自刷新/保持状态。 如果您需要用于预算的等效电流，请使用： 因此， 15.1 mW大约相当于： 假定的供应基础 等效电流 5.0V 输入 3.0 毫安 3.3V 输入 4.6毫安 这是等效输入电流，而不是单个 SoC 电源轨电流；实际处理器电流分布在多个电源轨上。 如果您指的是电路板/SOM 深度睡眠电流，则测量值可能会更高，并且取决于配置。一项 i.MX93 SOM DSM 测量报告显示，在 5 V 时电流为 4.04 mA ，而其他优化/配置相关的报告显示，在 5 V 时电流约为 1.5 mA 至 9.3 mA 。 处理器规格中典型的 SUSPEND 功耗为 15.1 mW ；仅根据实际输入电压转换为 mA，例如5 V 时约为 3.0 mA 。

What is the min to max sleep current mA for the iMX 937 processor   In my project I am using I.MX937 processor, what is the typical sleep current (mA) for the i.MX 937 processor?    Re: What is the min to max sleep current mA for the iMX 937 processor With those resources required to stay functional, 150 µA sleep current is not realistic for the i.MX 937 / i.MX 93 processor itself . Why: Mode Current/power implication Fits 150 µA? Functional fit BBSM / RTC mode Datasheet lists 0.14 mW at 1.8 V , and the power-measurement app note shows about 97.978 µW total , with only  NVCC_BBSM_1P8  active. Power-wise, yes No — only BBSM/RTC logic remains powered; GPIO wakeup is OFF, and timer/PWM/ADC are not available. Suspend Datasheet lists 15.1 mW typical at 25 °C. No — far above 150 µA equivalent No / limited — suspend turns off clocks, powers down the Cortex-A55, and powers down internal logic/analog blocks that can be shut off. Linux Suspend + M33 in WFI App note lists 122.4 mW total for this use case. No Closer architecturally, but still far above your current target. Low-power run / AONMIX using Cortex-M33 AONMIX can run while other domains are powered down, and includes timer/PWM and timer resources. Not documented as meeting 150 µA This is the relevant i.MX 93 mode class if peripherals must remain active, but it is not a 150 µA-class mode.   A 150 µA budget corresponds to only 0.27 mW at 1.8 V or 0.495 mW at 3.3 V . That is in the range of the i.MX 93 BBSM/RTC-only state, not a state with active timer output, ADC, PWM, RTC, and GPIOs. Recommended architecture: keep the i.MX 937 in BBSM/RTC or fully power-gated sleep , and move the always-on functions — timer output, ADC monitoring, PWM, and GPIO supervision — to a very-low-power companion MCU or analog/RTC circuit. The companion device can wake the i.MX 937 when the condition is met. The i.MX 937 can meet ~150 µA only in a very limited RTC/BBSM-style state; it cannot keep timer/PWM/ADC/GPIO functionality active within that current budget. Re: What is the min to max sleep current mA for the iMX 937 processor In our application, the following resources are required to remain functional during the low-power/sleep mode: 1 Timer output pin 1 ADC input 1 PWM RTC 2–3 GPIOs Our requirement of sleep current is 150 µA. Re: What is the min to max sleep current mA for the iMX 937 processor For the i.MX 937 / i.MX 93 processor itself, the datasheet does not give a single “sleep current” in mA. It specifies SUSPEND mode total power = 15.1 mW at 25 °C , and notes that the number is use-case dependent . SUSPEND is the lowest-power mode where clocks are off, unnecessary supplies are off, power-gateable SoC portions are gated, Cortex-A55 is fully power-gated, and DRAM is in self-refresh/retention. If you need an equivalent current for budgeting, use: So 15.1 mW corresponds approximately to: Assumed supply basis Equivalent current 5.0 V input 3.0 mA 3.3 V input 4.6 mA That is an equivalent input current , not a single SoC rail current; the actual processor current is distributed across multiple power rails. If you mean board/SOM deep-sleep current , measured values can be higher and configuration-dependent. One i.MX93 SOM DSM measurement reported 4.04 mA at 5 V , with other optimized/configuration-dependent reports around 1.5 mA to 9.3 mA at 5 V . Use 15.1 mW typical SUSPEND power for the processor spec; convert to mA only against your actual input rail, e.g. about 3.0 mA at 5 V .

如何通过 MUCXpresso SDK 创建示例后更改内存配置？ 我知道在使用 MCUXpresso SDK 创建示例时，我们可以配置内存。但是我已经创建了示例，并且更改了该示例中的许多文件，现在我想更改示例的内存配置（由于更改的文件数量非常大，我无法创建新示例、设置内存并再次更改文件）。 创建示例后是否可以配置内存配置？如何配置？谢谢。 我找到了这个方法：右键单击项目=>属性 => C/C++ 版本 => MCU 设置。这样对吗？ Re: How to change memory configuration after creating sample from MUCXpresso SDK? 嗨@nnxxpp ， 感谢您对 NXP MIMXRT 系列产品的关注！ 是的，SDK 示例创建完成后，可以更改内存配置。无需重新创建该项目。 您还可以参考这篇帖子： https://community.nxp.com/t5/MCUXpresso-General/MCUXpresso-Memory-map/mp/1062500   更新内存配置后，请清理并重新构建项目，并验证生成的链接器脚本和映射文件。 这适用于项目使用 MCUXpresso 管理的链接器脚本的情况。如果使用自定义 .ld 文件，请直接修改该链接器脚本。 此外，我还想提一下IDE提供的图像查看窗口，它可以让您轻松检查生成的图像布局是否符合您的要求： 此致， 加文 Re: How to change memory configuration after creating sample from MUCXpresso SDK? @Gavin_Jia 是的，谢谢，现在我不用重新创建项目就能配置内存了。

Toolbox setup and how to run an application 1 Table of Contents •Introduction •Overview •Context •References •Conclusion 2 Introduction This article walks through the complete process of setting up the NXP Model-Based Design Toolbox (MBDT) and running a first application on NXP hardware. Before starting the installation, make sure that the prerequisite toolboxes are available in MATLAB. By the end of this guide, the reader will have a fully functional MBDT environment and will have successfully generated, compiled, and deployed embedded C code from a Simulink model to NXP hardware. 3 Overview This guide begins with the installation prerequisites and required toolboxes, then continues with the MATLAB Add-On Explorer flow for installing NXP_Support_Package_S32K3 . After the support package is installed, the guide explains how to launch the multistep installer, verify the required toolboxes and installation path, download the toolbox package from NXP, and complete the toolbox installation before running the first application. Installation Scope and Workflow This article focuses on practical installation flow required to start working with the NXP Model-Based Design Toolbox and run a first example application. It covers the software prerequisites, the toolbox setup sequence, and the validation steps needed before opening and deploying a model on the target board. The installation content in this guide should use the current multistep installer flow. Target Audience This article is intended for engineers and technical professionals who want to begin developing embedded applications for NXP hardware using a Model-Based Design workflow. The main target audience includes: Embedded software engineers MATLAB / Simulink developers evaluating NXP hardware Control and algorithm engineers Students and academic researchers using NXP evaluation boards Model-Based Design engineers Hardware integration engineers 4 Context 3.1 Prerequisites Before starting the installation, verify that the following prerequisite toolboxes and setup conditions are met: MATLAB installed - Required by the support package and multistep installer flow. Simulink installed - Required for model-based development and Simulink example execution. Embedded Coder installed - Required for embedded C code generation from Simulink models. MATLAB Coder installed - Required by the current S32K3 support package prerequisites. Simulink Coder installed - Required by the current S32K3 support package prerequisites. Embedded Coder Support Package for ARM Cortex-M Processors installed - Required by the installer verification step and target support flow. NXP account - Required to access the NXP download page and retrieve the toolbox package. Short local installation path - The installation path should be local, short, and should not contain whitespace to avoid setup issues. Figure 1 - MATLAB Add-On Manager confirming requirement are installed 3.2 Toolbox Setup NXP's Model-Based Design Toolbox is delivered as a MATLAB Toolbox Package that can be installed offline or online from MathWorks Add-ons. The recommended installation path uses the NXP Support Package, a graphical wizard that guides through download, installation, and license activation in a single workflow. Note: Throughout this guide, the placeholder {platform} refers to the NXP MCU family targeted by the toolbox (for example S32K3 , S32K1 , S32M2 , MPC57XX , etc.). Each family has its own dedicated Support Package and Toolbox in the MATLAB Add-On Explorer. When following the steps below, replace {platform} with the identifier matching the hardware family in use, for instance, for the S32K3 evaluation boards, the script name becomes NXP_Support_Package_s32k3.m and the path command becomes mbd_s32k3_path . Step 1 - Install NXP Support Package from MATLAB Add-On Explorer Install the current NXP support package directly from the MATLAB Add-On Explorer. This package provides the multistep installer flow used to verify prerequisites, download the toolbox, and guide the installation for S32K3. In MATLAB, navigate to Home → Add-Ons → Get Add-Ons. Figure 2 - Open the Add-On Explorer from the MATLAB Home tab Search for NXP_Support_Package_S32K3 in the Add-On Explorer. Figure 3 - Search results for NXP_Support_Package_S32K3 in the Add-On Explorer Open the package page and click Add to start the installation. Figure 4 - Open the NXP_Support_Package_S32K3 page and click Add Review the license agreement for NXP_Support_Package_S32K3 and click I Accept. Figure 5 - License agreement shown during installation of NXP_Support_Package_S32K3 Wait for the installation to complete. When finished, the Getting Started Guide opens automatically. Figure 6 - Support package installation completed successfully In the MATLAB Command Window, run sp_s32k3.nxp.setup(); to launch the multistep installer. sp_s32k3.nxp.setup(); Figure 7 - Run sp_s32k3.nxp.setup(); from the MATLAB Command Window Step 2 - Use the multistep installer to download and install the toolbox The multistep installer guides you through prerequisite verification, toolbox download, installation, activation, and access to the documentation for S32K3. Figure 8 - Welcome page of the S32K3 multistep installer In the installer, continue to the download step. On the NXP website, review the software terms and conditions and click I Agree before downloading the toolbox package. If the product download page does not open automatically, sign in to your NXP account and open the Product Download page for the required S32K3 toolbox release or click the link from Download page of the S32K3 multistep installer. Figure 9 - Download page of the S32K3 multistep installer Figure 10 - Accept the NXP software terms and conditions before downloading Download the toolbox package from the Product Download page. The installer accepts both .zip and .mltbx files. Figure 11 - Product Download page for the S32K3 MBDT package The setup verification step checks whether all required toolboxes are installed in MATLAB and whether the installation path is valid for the S32K3 toolbox setup. If any dependency is missing or an unsupported version is detected, resolve the issue before continuing to the download and installation steps. Figure 12 - Setup verification page showing required toolboxes and installation path checks Important: It is recommended to install MATLAB and the NXP Toolbox into a location that does not contain special characters, empty spaces, or mapped drives. Use a short local path whenever possible. After downloading the package, return to the installer and continue with the local file selection step. Browse to the downloaded archive or toolbox package and click Install to continue. The installer accepts both .zip and .mltbx files. Figure 13 - Browse to and download the S32K3 MBDT package from the Product Download page Figure 14 - Accept the license agreement for NXP_MBDToolbox_S32K3 Accept the toolbox license agreement to allow MATLAB to complete the MBDT installation. Figure 15 - Toolbox installation in progress After the installation is complete, use the Add-On Manager context menu to open the installed toolbox folder if you need to inspect the package contents or access installed files directly. Wait until the installation finishes. The process may take several minutes depending on the system configuration and package size. Figure 16 - Open the installed toolbox location from MATLAB Add-On Manager Step 4 - Set the Path for Toolchain Generation The MBDT uses Simulink's toolchain mechanism to enable automatic code generation with Embedded Coder. When installed as a MATLAB add-on, the toolbox path is configured automatically. If manual configuration is still required in your environment, run the platform path script from the installation directory. If manual setup is required, in MATLAB change the Current Directory to the toolbox installation folder: ..\MATLAB\Add-Ons\Toolboxes\NXP_MBDToolbox_{platform}\ Then run the configuration script: mbd_{platform}_path Figure 17 - Output of the mbd_{platform}_path script in the MATLAB Command Window 3.3 How to Run an Application With the toolbox installed and the compiler configured, the following steps demonstrate how to open, build, and deploy the LED blinky example - the embedded equivalent of Hello World to an NXP evaluation board. Open an Example Model Open MATLAB and start Simulink by typing simulink in the Command Window (or by clicking the Simulink button on the Home tab). In the Simulink Start Page, open the Simulink Library Browser (View → Library Browser, or press Ctrl+Shift+L). In the Library Browser tree, expand NXP Model-Based Design Toolbox for {platform} to confirm that the NXP blocks are available. This validates that the toolbox is properly registered with Simulink. Open the Example Projects tab from the Simulink Start Page, it lists every example shipped with the MBDT, grouped by peripheral (ADC, CAN, DIO, PWM, UART, etc.). Browse the list, select the example matching your hardware (for instance s32k3xx_dio_s32ct for the LED blinky on FRDM-A-S32K312 / FRDM-A-S32K344 ), and click Open to load the model. Figure 18 - MBDT Examples Library available from the Simulink Library Browser Open the example model ( .slx / .mdl file). Configure the Target Hardware Figure 19 - Model Settings  Figure 20 - Code Generation Tip: Example models that ship with the MBDT are pre-configured for a specific evaluation board. Always verify the hardware target matches your physical board before building. Build and Deploy Connect the NXP evaluation board to the PC via USB. In Simulink, open the Hardware tab and click Build, Deploy & Start (or use Ctrl+B). Monitor the MATLAB Diagnostic Viewer for build status messages. Verify on Hardware Confirm that the application runs on the target hardware as expected - for example, observe the LED blinking at the rate defined in the model. If the application produces serial output, open a terminal and verify the expected data on the communication port. Use debugging or monitoring tools to inspect variable values and system signals from the running application in real time. 5 References NXP Model-Based Design Toolbox - Product Page Automotive SW - S32K3 - Model-Based Design Toolbox Model-Based Design Toolbox S32K3xx Quick Start Guide (PDF) MathWorks Embedded Coder 6 Conclusion This article described the complete setup of the NXP Model-Based Design Toolbox: from installation and compiler configuration to building and deploying a first application to NXP hardware. The next article in the series focuses on the Toolbox Workflow, presenting in detail the end-to-end development flow with the MBDT, from configuring a Simulink model with NXP blocks, through code generation with Embedded Coder, to building, deploying and validating the resulting application on NXP hardware.

Front and Rear Lights-Overview 1 Table of Contents • Introduction • Overview • Context • References • Conclusion 2 Introduction Automotive lighting systems play an essential role in vehicle safety, visibility, and communication with other road users.

Both help provide road illumination for the driver and signal the vehicle's actions and presence to surrounding traffic. Front Lights - General Role and Functions Front lighting improves the driver's visibility in different driving conditions, including low light, nighttime driving, and adverse weather. It includes several key functions commonly found in modern vehicles, such as: Daytime Running Lights (DRL) - increase vehicle visibility during daytime driving Turn Lights - indicate the driver's intention to change direction Head Lights - provide road illumination during nighttime or low-light conditions Fog Lights - improve visibility in fog, rain, snow, or other low-visibility situations Rear Lights - General Role and Functions Rear lighting is primarily used to communicate the vehicle's status and intentions to other road users. It includes important functions such as: Stop Lights - signal braking actions Head Lights - make the vehicle visible from behind Turn Lights - indicate the intended direction of travel Fog Lights - improve vehicle visibility in low-visibility conditions 3 Overview The lighting system presented in this article is developed using a Model-Based Design (MBD) approach. This methodology enables early validation of system behavior, systematic refinement of the control logic, and a direct path from simulation to embedded implementation. The control behavior is modeled in MATLAB/Simulink, where the functionality is structured into modular and reusable components. Stateflow is used to describe the control logic, providing a clear and formal representation of operating modes, state transitions, and event-driven behavior. The Simulink model runs on the NXP S32K3 platform and communicates with other vehicle nodes via CAN Bus. Message reception and signal handling are managed using the Vehicle Network Toolbox, which simplifies CAN communication by utilizing DBC files without introducing additional hand-written interface code. This integration supports a smooth transition from simulation to embedded deployment through automatic code generation, minimizing the risk of discrepancies between modeled behavior and deployed software. Target audience: Engineers interested in Model-Based Design for automotive applications Those learning or experimenting with simulation-based development and control logic Anyone using NXP automotive hardware platforms who wants to faster develop complex applications on real embedded systems Figure 2 - Front Hazard Lights Activated 4 Context In this project, separate models are implemented for front and rear lighting to showcase the physical layout of the car and keep the logic simple and easier to test. Each lighting area handles its own functions, while staying synchronized with overall vehicle behavior through standard vehicle communication. Figure 1 - Front and Rear Lights System highlighted within the EV architecture All lighting commands are received via the CAN bus, ensuring consistent and predictable behavior for functions such as Daytime Running Lights (DRL), Head Lights, Fog Lights, Turn Indicators, and Stop Lights. Using CAN-based commands reflects standard vehicle communication practices and allows the lighting logic to be evaluated under conditions close to those in a production system. Incoming CAN messages are processed by the lighting module. Based on vehicle states and received commands, the module: interprets CAN signals and system status, prioritizes lighting functions and handles fault-related conditions, turns on the lights. This structure keeps responsibilities clear: the CAN layer provides high-level commands, while the lighting control logic handles decision-making and execution. The result is a deterministic and easy-to-follow path from vehicle-level inputs to visible lighting behavior. In our project, the system uses addressable LEDs, allowing individual control of multiple light segments within each lamp. This enables a realistic representation of modern automotive lighting systems, where lighting units are no longer simple on/off devices but consist of multiple independently controlled segments. Addressable LEDs rely on a dedicated communication protocol to transfer control data such as color, brightness, and activation timing to each individual LED element. To simplify the integration of this protocol and ensure deterministic behavior, the LED communication was configured and integrated using NXP's Model-Based Design workflow. This approach allows the LED control logic and communication timing to be defined, simulated, and validated directly at model level. The system behavior can be easily followed from input to output, since each step is clearly defined. CAN messages trigger specific actions, and the result is directly visible in the LEDs. This makes the logic straightforward to understand and verify. 5 References Model-Based Design Toolbox (MBDT) Community Model-Based Design Toolbox (MBDT) - S32K3 - How To 6 Conclusion This article provides a simple overview of how Model-Based Design can be applied to develop an automotive lighting system using NXP hardware, focusing on the general architecture and design approach. In the following articles, we will explain the configuration, implementation, and deployment of the lighting system on the NXP hardware.

S32 Design Studio - Export and Debug 1 Table of Contents • Introduction • Open the generated project in S32 Design Studio • Debug the generated application in S32 Design Studio • Debug the code generated from the Simulink model • Conclusion 2 Introduction This article explains how to take a project generated with the Model-Based Design Toolbox (MBDT) in Simulink and open, build, and debug it in S32 Design Studio. It focuses on the transition from model execution in Simulink to target-level debugging and validation on S32 hardware. 3 Open the generated project in S32 Design Studio MBDT generates code from Simulink models and exports it as an S32 Design Studio-compatible project. After a successful model build, the generated _Config folder contains the files required by the IDE. The project can then be opened directly from Simulink or imported into S32 Design Studio for further configuration, building, and debugging on S32 hardware. Before opening or debugging the project in S32 Design Studio, build the Simulink model. The build process generates the code and project structure required for IDE integration. You can open the generated project either directly from Simulink or manually from within S32 Design Studio. Use the Simulink option when you want to launch the generated project immediately after configuration. Use the IDE import option when you want to manage the project manually from an S32 Design Studio workspace. Open the project from Simulink To open the project from Simulink, open the model Hardware Settings from the Hardware tab or press Ctrl + E. Then go to Hardware Implementation → Hardware board settings → Target hardware resources → S32 Design Studio Project and select Open. Figure 1. S32 Design Studio project settings in Simulink A dialog appears and prompts you to select the S32 Design Studio installation path. Figure 2. S32 Design Studio installation path selection To select the S32 Design Studio installation path later, or to change it during toolbox usage, click Browse in the S32 Design Studio location field under the Tools Paths group. Figure 3. S32 Design Studio path changing The generated project opens in S32 Design Studio and is ready to build, configure, or debug. Figure 4. Generated project opened in S32 Design Studio Open the project inside the IDE To import the project manually into S32 Design Studio, follow these steps: Inside the IDE, select File → Import → Existing Projects into Workspace. Figure 5. Importing an existing project into the workspace Browse for the _Config folder in Select root directory. Before clicking Finish, make sure that Copy projects into workspace is disabled. If the project is copied into the S32 Design Studio workspace, the build process will fail. Figure 6. Directory selection for the generated project 4 Debug the generated application in S32 Design Studio To build and debug the project in S32 Design Studio, select the project and click Debug. S32 Design Studio builds the project and automatically switches to the Debug perspective. Note: Ensure that the target hardware board is connected before starting the debug session. Figure 7. Starting the debug session Figure 8. Debug perspective in S32 Design Studio After the debugger launches and the application is loaded on the target, you can use the following actions to control program execution and inspect the generated code: The Breakpoint action sets a breakpoint when you double-click in the left margin of a .c file:   Figure 9. Breakpoint set in the generated source file The Step Over (F6) action executes the current line while remaining in the same function: Figure 10. Step Over action in the Debug toolbar The Step Into (F5) action enters a called function: Figure 11. Step Into action in the Debug toolbar The Step Return (F7) action runs to the end of the current function: Figure 12. Step Return action in the Debug toolbar The Resume (F8) action runs until the next breakpoint: Figure 13. Resume action in the Debug toolbar Figure 14. Breakpoint reached after pressing Resume action The Suspend (F9) action pauses execution at the current instruction: Figure 15. Suspend action in the Debug toolbar Figure 16. Function paused after pressing Suspend action The Terminate (Ctrl + F2) action stops the debug session and disconnects from the target: Figure 17. Terminate action in the Debug toolbar The Disconnect action leaves the target running while detaching the debugger: Figure 18. Disconnect action in the Debug toolbar 5 Debug the code generated from the Simulink model The code generated by the Simulink model can be found in the _step() function. To enter this function, set a breakpoint before the function call, run the application until the breakpoint is reached, and then select Step Into. Alternatively, Ctrl + Click the function name to open the function and place a breakpoint inside it. Figure 19. modelName_step function In this function, you will also find the generated code for the blocks placed inside the Simulink model. Figure 20. Generated step function in the source code To monitor variable values, hover over a variable to see its current value: Figure 21. Variable value displayed on hover Alternatively, add the variable to the Expressions view by selecting Add new expression, entering the variable name, and pressing Enter. Figure 22. Add new expression in Expressions view Figure 23. Variable added to Expressions view Upon running the code, if the value changes, it will be highlighted. Figure 24. Variable value highlighted during debug The names of the variables in the generated code are the same as the names they have in the Simulink model, making it easier to debug the generated code. Figure 25. Variable name in Simulink model and generated code 6 Conclusion After identifying the generated function and monitoring key variables, you can validate how the Simulink model behavior maps to the generated application running on the target hardware.

Re: TJA1120A 1000BASET1 Linux side configuration こんにちは、 @vikyhre さん。 新しいログを見る限り、1000BASE-T1側は正常に動作しているようです。TJA1120 PHYが検出され、リンクは1 Gbit/sで確立され、マスター/スレーブの状態は正しく、SQIは7/7と報告されています。 しかし、イーサネットインターフェースの統計では、受信パケットはゼロであり、送信パケットは増加しています。これは受信フレームがLinuxのMAC/ネットワークスタックに届いていないことを示唆しています。 LinuxデバイスツリーでRGMIIのタイミング設定を再確認してください。ログにはインターフェースが「phy/rgmii」として設定されていることが示されています。基板設計でPHYが内部RGMII遅延を提供することを想定している場合、デバイスツリーは通常単なる「rgmii」インスタンスではなく 「rgmii-id」 を使うべきです。RGMIIの遅延設定の不一致はまさにこのような動作を引き起こすことがあります:PHYリンクアップと良好なSQIはあるものの、Linuxによるパケット受信は成功しません。 PC側のWiresharkでECUから送信されたフレームが見えるかどうかも確認してもらえますか?例えば、eth0をECUに起動した後、ECUのMACアドレスからのARP、IPv6の隣接検出、その他のイーサネットフレームがPC上でキャプチャされているか確認してください。 同時に、PCからpingを実行しながら、ECU側でtcpdumpを実行してください。 tcpdump -ni eth0 -e arp または icmp ARP/ICMPパケットがキャプチャされず、RXカウンタがゼロのままの場合、問題は1000BASE-T1リンク自体ではなく、MAC-to-PHY RGMIIパスまたはそのデバイスツリーのタイミング構成にある可能性が最も高いです。 よろしくお願いいたします。 パベル Re: TJA1120A 1000BASET1 Linux side configuration パベルさん、おっしゃる通り、CONFIG3、4ピンをRGMII-IDに設定しました（TJA1120Aデータシートの6.7.2に従って、RGMII-IDとRGMII-ID（TX/RX）の両方を試しました）。また、phy-modeを「rgmii-id」に設定してください。 &cpsw_port1 { status = "okay"; phy-mode = "rgmii-id"; phy-handle = <&cpsw3g_phy0>; }; これはdmesgに反映された。 [ 6.817790] am65-cpsw-nuss 8000000.ethernet eth0: configuring for phy/rgmii-id link mode しかし、pingは依然として機能していなかった。 acs@a-tract-10:~$ ping 192.168.1.100 PING 192.168.1.100 (192.168.1.100) 56(84) bytes of data.

また、静的ARPエントリを追加した結果、ECU側とPC側の両方でtcpdumpにメッセージが表示されなくなりました。 ECU PHYが応答していないようです。 Re: TJA1120A 1000BASET1 Linux side configuration こんにちは、 @vikyhre さん。 したがって、問題はECUからPCへの送信方向にあるようです: ECU MAC TX パス、 MACとTJA1120A間のRGMII TXタイミング/遅延設定、 TJA1120送信経路、 メディアコンバータ受信経路、 またはRGMIIインターフェース上の信号整合性/ボードレベルのタイミングも考慮されます。 CONFIGピンのストラップはリセット後のデフォルト構成を定義しますが、NXP TJA11xx Linux**ドライバ**がアクティブな場合、Linuxデバイスツリーに従ってMDIOを通じてPHYを再構成できます。つまり、ピンストラップは実際には効果がありません。 1.片方向のみが影響を受ける場合は、例えば以下の通り、該当する方向性RGMII遅延バリアントをテストすると良いでしょう。 phy-mode = "rgmii-id"; /* RXおよびTXの内部遅延 */ phy-mode = "rgmii-rxid"; /* 受信内部遅延のみ */ phy-mode = "rgmii-txid"; /* TX内部遅延のみ */ phy-mode = "rgmii"; /* PHY内部遅延なし */ また、選択したLinuxの物理モードが、ハードウェア設計の意図されたMAC/PHY遅延所有権と一致していることを確認してください。   2. 並行して、ECUからPCへのトラフィックを生成し、RGMII TXピンにアクティビティがあるかどうかを確認することもお勧めします。例えば、以下を実行できます: ping *I eth0 192.168.1.101   そして、MACとTJA1120A間のRGMII TX信号をオシロスコープで監視する。 TXC、 TX_CTL、 TXD[3:0]。 Linuxが送信を試みている間にこれらのピンに活動がなければ、問題はPHYの前のMAC/ドライバー/設定パスにまだ存在している可能性があります。RGMII TXピンに活動があるがPC側で有効なフレームが検出されない場合は、RGMII TXのタイミング、遅延設定、信号品質、またはメディアコンバータ受信経路に注目すべきです。   3. また、PCに期待されるインターフェースを強制しつつ、静的ARPテストを繰り返してください: sudo ip neigh replace *92.168.1.100lladdr 64:1c:10:1c:06*e2 dev eno1 nud permanent ip neigh*show 192.168.1.100dev eno1 ip rou*e get 192.168.1.100 sudo tcpdump -*ni eno1 -vvv '(arp または icmp)' ping *I eno1 192.168.1.100 注:上記のLinuxコマンドはあくまで例であり、特定のLinuxディストリビューション、ネットワークインターフェース名、システム構成に応じて調整が必要になる場合があります。 有効な静的ARPエントリがあれば、PCはARPリクエストを送信する必要がなくなります。ICMPエコー要求フレームをECUのMACアドレスに直接送信する必要があります。これらのフレームは、少なくともPC側のtcpdumpで確認できるはずです。PC側のtcpdumpでも出力ICMPフレームが表示されない場合は、PCルーティング、隣接テーブル、インターフェース選択を確認してください。 PC側では送信ICMPフレームが確認できるのにECU側では確認できない場合、PCからECUへのユニキャストトラフィックの通信はまだ完全には機能していない。ECUがICMPフレームを受信して応答を生成するにもかかわらず、PCがそれを受信しない場合、問題はECUからPCへの送信方向にあると考えられます。   よろしくお願いいたします。 パベル Re: TJA1120A 1000BASET1 Linux side configuration こんにちは、 @vikyhre さん。 最新情報のご提供ありがとうございます。この新しい結果は非常に有用です。 現時点では、RGMII-IDは正常に動作すると仮定してよいだろう。 重要な点として、PCからのARP要求はVLAN 0優先度タグ付きフレームであるということが挙げられる。 ethertype 802.1Q、vlan 0、ethertype ARP 一方、ECUのARP応答はタグなしのARPフレームである。PCインターフェース、ブリッジ、VLAN、QoS、またはドライバー/オフロード構成がタグ付きトラフィックを想定しているか、タグなしのARP応答がARPリクエストにフィルタリングされているか、または関連していないかを確認してください。 注:以下のLinuxコマンドはあくまで例であり、特定のLinuxディストリビューション、ネットワークインターフェース名、システム構成に応じて調整が必要になる場合があります。 PC側のトラフィックをキャプチャしてください。 sudo tcpdump -eni -vvv '(arp または icmp または vlan)' それから再びpingを開始します。 PCキャプチャでECU MACアドレス「64:1c:10:1c:06:e2」からのARP応答が表示されない場合、問題は依然としてECUからPCへの送信パスまたはメディアコンバーターパスにあります。   PCキャプチャでARPの返信が表示されても、PCが「宛先ホストに到達不可」と表示される場合、PC側のLinuxネットワーク/VLAN/フィルタリング設定に問題がある可能性が高いです。   追加の隔離テストとして、PCに静的なARPエントリを追加してみてください。   sudo ip neigh replace 192.168.1.100lladdr 64:1c:10:1c:06:e2 dev nud permanent   次に、両側のトラフィックをキャプチャしながら、ピングを繰り返します。 よろしくお願いいたします。 パベル Re: TJA1120A 1000BASET1 Linux side configuration こんにちは、 @vikyhre さん。 最新情報のご提供ありがとうございます。これは非常に良いニュースです。今はうまくいっているようで良かったです。 ログには不審な点は見当たりませんし、明らかに欠落しているものも見当たりません。最終的な確認として、iperf3テストを逆方向に実行してみるのも良いでしょう。 「rgmii-txid」に関するご懸念についてですが、この名前はLinuxの汎用デバイスツリー「phy-mode」値です。必ずしも同じLinux名でTJA1120Aデータシートに表示される必要はありません。TJA1120A RGMII TXCおよびRXCクロックパスにおける独立した遅延設定をサポートしています。レジスタRGMII_TXC_DELAY_CONFIGおよびRGMII_RXC_DELAY_CONFIGを参照してください。そしてピンストラップは当然ながら限られた構成セットしかサポートしていません。   もし前回の返信で問題解決に役立ったなら、他のユーザーが参照しやすくするために、その回答を解決策としてマークしていただけると嬉しいです。 よろしくお願いいたします。 パベル Re: TJA1120A 1000BASET1 Linux side configuration パベルさん、貴重なご意見ありがとうございます。 動作確認済み 私が懸念しているのは、TX_CLKに対する遅延のみである「rgmii-txid」がTJA1120Aのデータシートに記載されていないことです。しかし、それでも「rgmii-txid」は私たちの場合はうまく機能しました。この点についてご説明ください。DTはストラップを上書きできるとおっしゃっていたので、DTで「rgmii-txid」CONFIG_PIN変更しました。参考までに、PINストラップは現在RGMII-IDに設定されています（データシートの通り、RXのみ遅延が発生します）。

如何在不启用任何中断的情况下将 LPI2C 外设与 DMA 配合使用？ 你好， 我正在使用NXP S32K396 MCU ，并且希望在不启用任何中断的情况下使用 eDMA 执行 LPI2C 主站事务。在我的项目中，我使用了LPI2C1外设。 当启用以下中断时，我可以使用 DMA 成功执行 LPI2C 读写事务： LPI2C1_IRQn eDMA0_DMATTCD_CH16_CH17_IRQn 然而，RTD LPI2C DMA 实现似乎依赖于这些中断。 在 Lpi2c_Ip_MasterSendData() 函数中，LPI2C 主中断始终由驱动程序启用： 此外，通过 Lpi2c_Ip_MasterTxDmaConfig() 和 Lpi2c_Ip_MasterRxDmaConfig() 配置的 TX 和 RX 的 DMA TCD 始终启用 DMA 主循环完成中断： Lpi2c_DmaTransferList[9u] .Param = DMA_IP_CH_SET_CONTROL_EN_MAJOR_INTERRUPT ; Lpi2c_DmaTransferList[9u] .Value = 1U; 我还注意到，在其他函数中 - Lpi2c_Ip_MasterSendDataBlocking() 似乎没有为 LPI2C 传输配置 DMA TCD。 我希望使用 DMA 执行完整的 LPI2C 发送和接收事务，同时禁用 LPI2C1_IRQn 和 eDMA 通道中断。   如果可以的话，NXP能否提供一个使用DMA的LPI2C主控端TX/RX示例，其中LPI2C和DMA中断均被禁用？   MCU：NXPS32K396 RTD：6.0.0 NXP Studio：3.6.1   非常感谢您的帮助。非常感谢！ 如有需要，我可以附上我的项目文件。 Re: How to use LPI2C peripheral with DMA without enabling any interrupts? 你好@ rkhw 从当前的驱动程序实现来看，“Lpi2c_Ip_MasterSendData()”依赖于LPI2C主中断和DMA主循环完成中断来进行传输完成和状态处理。 因此，如果不启用中断，就无法启用 DMA。RTD驱动程序不支持此用法。

Re: I need to configure DMA for SPI ご回答ありがとうございます。 この作業はs32k322 MCUで行ってください Re: I need to configure DMA for SPI こんにちは@ershi RTDにはDMAを用いたSPI通信用の2つの例コードが付属しており、1つは低レベルドライバ(Ip)を用い、もう1つは高レベルドライバ(MCAL)を使用します。例のインポート方法については、HOWTO: S32 Design Studio - Create a New S32DS Project from Example Threadを参照してください。 また、スレッドの 例であるS32K31 SPI Multiple Packet Transmit and Receive: Solution for DMA Cache Issueの例を参照することもできます。 BR、VaneB Re: I need to configure DMA for SPI こんにちは@ershi これらの例はS32K322向けに特別に設計されているわけではありませんが、リファレンス・マニュアルに特に記載されていない限り、S32K3 ファミリ全体で機能性は概ね同じです。したがって、このプロジェクトを実装の参考として活用し、必要に応じてデバイスに合わせて調整することができます。 Re: I need to configure DMA for SPI すべて設定しましたが、最初は動作せず、(Lpspi_Ip_AsyncTransmit)でLPSPI_IP_STATUS_SUCCESSとして返され、2回目は失敗と表示されますLPSPI_IP_STATUS_FAIL、DMAなしでこのAPIを使ってデータをSPI経由で送信できますLpspi_Ip_SyncTransmit()いくつかの設定スクリーンショットを添付しました。 Re: I need to configure DMA for SPI こんにちは@ershi RMやIntCtrl_Ipドライバーの設定画像も共有してもらえますか? Re: I need to configure DMA for SPI こんにちは、 @VaneBさん RMとIntCtrl_IPドライバの設定のスクリーンショットと、詳細な参考のために短い動画クリップを添付しました。 LPSPIの設定ページで1つの違いに気づきました。SPI GeneralタブのSpi_Phy_TxDmaChannelの項目で、TX設定とRX設定で名前が異なっています。 追加情報が必要な場合はお知らせください。 InterruptsInterrupts割り込み RMRMRM Re: I need to configure DMA for SPI こんにちは@ershi 情報を共有していただきありがとうございます。 一つだけ気づいたことがあります。Dma_Ipドライバー構成では、DMA_SPI_CALLBACK_0を割り込みコールバックとして定義しています。しかし、LPSPI DMAのコールバックはドライバーから既に提供されており、Lpspi_Ip_Irq.cで見つけることができますファイル。 LPSPI2の場合、設定するコールバックは以下のとおりです。 TX DMAチャネルのLpspi_Ip_LPSPI_2_IrqTxDmaHandler RX DMAチャネルのLpspi_Ip_LPSPI_2_IrqRxDmaHandler

Re: TJA1120A 1000BASET1 Linux side configuration Hello @vikyhre , Based on the new logs, the 1000BASE-T1 side seems to be working correctly. The TJA1120 PHY is detected, the link is up at 1 Gbit/s, the master/slave status is correct and SQI is reported as 7/7. However, the Ethernet interface statistics still show RX packets equal to zero while TX packets are increasing. This suggests that the received frames are not reaching the Linux MAC/network stack. Please re-check the RGMII timing configuration in the Linux device tree. The log shows that the interface is configured as "phy/rgmii". If your board design expects the PHY to provide the internal RGMII delays, the device tree should typically use "rgmii-id" instead of plain "rgmii" instance. A mismatch in RGMII delay configuration can result in exactly this behavior: PHY link up and good SQI, but no successful packet reception by Linux. Could you also check with Wireshark on the PC side whether any frames transmitted by the ECU are visible there? For example, after bringing eth0 up on the ECU, please check whether ARP, IPv6 neighbor discovery or any other Ethernet frames from the ECU MAC address are captured on the PC. At the same time, please run tcpdump on the ECU side while pinging from the PC: tcpdump -ni eth0 -e arp or icmp If no ARP/ICMP packets are captured and the RX counter remains zero, the issue is most likely still in the MAC-to-PHY RGMII path or its device-tree timing configuration, not in the 1000BASE-T1 link itself. Best regards, Pavel Re: TJA1120A 1000BASET1 Linux side configuration Pavel, just as you said I made CONFIG3,4 pins to RGMII-ID (as per 6.7.2 of TJA1120A Datasheet, I tried both RGMII-ID and RGMII-ID (TX/RX) ). Also set phy-mode as "rgmii-id" &cpsw_port1 { status = "okay"; phy-mode = "rgmii-id"; phy-handle = <&cpsw3g_phy0>; };  This was reflected in dmesg [ 6.817790] am65-cpsw-nuss 8000000.ethernet eth0: configuring for phy/rgmii-id link mode But pinging was still not working acs@a-tract-10:~$ ping 192.168.1.100 PING 192.168.1.100 (192.168.1.100) 56(84) bytes of data.

The new result is very useful. We may assume for now, that RGMII-ID works. One important observation is that the ARP requests from the PC are VLAN 0 priority-tagged frames: ethertype 802.1Q, vlan 0, ethertype ARP while the ECU ARP replies are untagged ARP frames. Please check whether the PC interface, bridge, VLAN, QoS or driver/offload configuration expects tagged traffic or whether untagged ARP replies are filtered or not associated with the ARP request. Note: The Linux commands below are intended as examples and may need to be adapted according to your specific Linux distribution, network interface name and system configuration. Please capture the traffic on the PC side: sudo tcpdump -eni -vvv '(arp or icmp or vlan)' Then start the ping again. If the PC capture does not show the ARP replies from ECU MAC address `64:1c:10:1c:06:e2`, then the issue is still in the ECU-to-PC transmit path or media-converter path.   If the PC capture shows the ARP replies, but the PC still reports “Destination Host Unreachable”, then the issue is most likely in the PC-side Linux network/VLAN/filtering configuration.   As an additional isolation test, please try adding a static ARP entry on the PC:   sudo ip neigh replace 192.168.1.100 lladdr 64:1c:10:1c:06:e2 dev nud permanent   Then repeat the ping while capturing traffic on both sides. Best regards, Pavel Re: TJA1120A 1000BASET1 Linux side configuration Hello @vikyhre , so the issue appears to be on the ECU-to-PC transmit direction: ECU MAC TX path, RGMII TX timing / delay configuration between the MAC and TJA1120A, TJA1120 transmit path, media converter receive path, or potentially signal integrity / board-level timing on the RGMII interface. The CONFIG pin strapping defines the default configuration after reset, but when the NXP TJA11xx Linux driver is active, the PHY can be reconfigured through MDIO according to the Linux device tree. So, pin strapping has actually no effect. 1. If only one direction is affected, it may be useful to test the applicable directional RGMII delay variants, for example: phy-mode = "rgmii-id";    /* RX and TX internal delay */ phy-mode = "rgmii-rxid";  /* RX internal delay only */ phy-mode = "rgmii-txid";  /* TX internal delay only */ phy-mode = "rgmii";       /* no PHY internal delay */ And, please make sure that the selected Linux phy-mode matches the intended MAC/PHY delay ownership for your hardware design.   2. In parallel, I would also recommend generating traffic from the ECU toward the PC and checking whether there is activity on the RGMII TX pins. For example, you can run: ping *I eth0 192.168.1.101   and monitor the RGMII TX signals by oscilloscope between the MAC and TJA1120A, especially  TXC, TX_CTL, TXD[3:0]. If there is no activity on these pins while Linux is trying to transmit, the issue may still be in the MAC/driver/configuration path before the PHY. If there is activity on the RGMII TX pins, but no valid frames are observed on the PC side, then the focus should be on RGMII TX timing, delay configuration, signal quality, or the media-converter receive path.   3. Please also repeat the static ARP test while explicitly forcing the PC to use the expected interface: sudo ip neigh replace *92.168.1.100 lladdr 64:1c:10:1c:06*e2 dev eno1 nud permanent ip neigh*show 192.168.1.100 dev eno1 ip rou*e get 192.168.1.100 sudo tcpdump -*ni eno1 -vvv '(arp or icmp)' ping *I eno1 192.168.1.100 Note: The Linux commands above are intended as examples and may need to be adapted according to your specific Linux distribution, network interface name and system configuration. With a valid static ARP entry, the PC should no longer need to send ARP requests. It should transmit ICMP Echo Request frames directly to the ECU MAC address. These frames should be visible at least in the PC-side tcpdump. If even the PC-side tcpdump does not show outgoing ICMP frames, please check the PC routing, neighbor table and interface selection. If outgoing ICMP frames are visible on the PC side but not on the ECU side, then the PC-to-ECU direction is still not fully working for unicast traffic. If the ECU receives the ICMP frames and generates replies, but the PC does not receive them, then the issue remains in the ECU-to-PC transmit direction.   Best regards, Pavel Re: TJA1120A 1000BASET1 Linux side configuration Thanks for your insight Pavel We got it running One concern i have is that "rgmii-txid" which is delay only to TX_CLK is not mentioned in TJA1120A Datasheet. But still 'rgmii-txid" worked for us.  Please clarify this. I changed in DT to "rgmii-txid" since you mentioned that DT can override CONFIG_PIN strapping. FYI PIN Strapping is currently at RGMII-ID (delay only on RX as per datasheet).

We assume everything is sorted by now, please tell us if we are missing anything. I will mark your reply as solution if you have nothing more to add. Thanks Re: TJA1120A 1000BASET1 Linux side configuration Hello @vikyhre , Thank you for the update. This is very good news. I'm glad it works for you now. I do not see anything suspicions in your logs - I do not see anything obviously missing. As a final sanity check, you may also run the iperf3 test in the reverse direction. Regarding your concern about `rgmii-txid`: this name is a Linux generic device-tree `phy-mode` value. It does not necessarily have to appear in the TJA1120A datasheet using the exact same Linux naming. TJA1120A supports independent delay configuration in the RGMII TXC and RXC clock paths - please refer to registers RGMII_TXC_DELAY_CONFIG and RGMII_RXC_DELAY_CONFIG. And the pin strapping naturally supports only limited set of configurations.   If my previous reply helped resolve the issue, please feel free to mark it as the solution for easier reference to other users.
