Voltage injection tests for OV and UV scenarios and associated behavior Hello Community,  SBC FS4503 is used in one of our projects and configured as below for OV / UV conditions. VCCA, VCORE and VAUX are configured to have impact on FS0B only in an OV condition and an impact on RSTB and FS0B both in case of an UV condition. Voltage injection test was performed by injecting voltages at the VCORE, VAUX and VCCA pins by using a second power supply while the first power supply provided 12V input to the SBC.  Results of the test as below: 1. VAUX OV - Asserts FS0B, 2. VAUX UV- Triggers RESET 3. VCORE OV- Asserts FS0B but VCORE is cut off, as mentioned in the data sheet. 4. VCORE UV- Triggers RESET 5. VCCA OV- Asserts FS0B, but VCORE is pulled down for a short time, and hence reset 6. VCCA UV- Triggers RESET. VPRE- OV - Datasheet mentions regulator is switched off, and we observe a RESET. Below are the queries: 1. Is the Bench test procedure valid? Where, for OV conditions around 5.5V was injected on the respective pin and for UV conditions around 3.5V was injected on the pins. 2. Is the observation with VCCA OV condition acceptable? 3. When an OV condition occurs at VPRE, the datasheet mentions the regulator is switched off, does this cut-off the VCORE supply as well? Thank you, Aditya Re: Voltage injection tests for OV and UV scenarios and associated behavior 1. Is the Bench test procedure valid? Where, for OV conditions around 5.5V was injected on the respective pin and for UV conditions around 3.5V was injected on the pins. [gw]OV should use voltage above 5.5V, UV test should be lower than 3V. Also need meet the filter time and reaction time requirement. 2. Is the observation with VCCA OV condition acceptable? [gw]Does the second power supply(OV voltage) reverse-supply through the VCCA pin, causing disturbances in the VPRE/VCORE loop? Did you monitor the VPRE during this VCCA OV test？ 3. When an OV condition occurs at VPRE, the datasheet mentions the regulator is switched off, does this cut-off the VCORE supply as well? [gw]Yes, VCORE is provided by VPRE. Re: Voltage injection tests for OV and UV scenarios and associated behavior Hello @guoweisun ,  Thank you for the response. This is helpful.  Please find my queries below: [gw]Does the second power supply(OV voltage) reverse-supply through the VCCA pin, causing disturbances in the VPRE/VCORE loop? Did you monitor the VPRE during this VCCA OV test？ [ab]: VPRE was not monitored. I will monitor it with new tests. Could you please help me understand what is meant by reverse-supply through VCCA pin? [gw]OV should use voltage above 5.5V, UV test should be lower than 3V. "Also need meet the filter time and reaction time requirement." [ab]: As I am performing this activity manually, the filter time of 100-200us and reaction time of 314us are satisfied for the OV cases.  Below are some additional queries,  1. How is OV/ UV detected, what is the sampling rate used by the SBC? 2. What is the significance of the filter time and reaction time? 2. How many not ok samples are allowed before detecting an OV/ UV fault on any of the pins? Thank you, Aditya

Battery Management System - SW & HW Environment Battery Management System Software and Hardware Environment 0 Table of Contents •Introduction •Software •Hardware •References •Conclusion 1 Introduction This article presents a comprehensive overview of the hardware and software components required to design and implement a high-voltage Battery Management System (BMS). It focuses on solutions based on NXP hardware platforms, combined with the integrated development ecosystems provided by NXP and MathWorks. The objective is to highlight how these technologies work together to streamline system development, deployment, and validation. 2 Software The software environment provides the modeling, simulation, communication, code generation, and deployment capabilities required by the Battery Management System. 2.1 Deep Learning Toolbox Deep Learning Toolbox brings artificial intelligence into the model-based workflow. It provides MATLAB functions, apps, and Simulink blocks for designing, training, simulating, and analyzing deep neural networks. This makes AI-based behavior easier to develop, understand, and validate before deployment. In the Battery Management System, deep learning can support battery state estimation, fault detection, and operating-condition classification. The toolbox can create and evaluate neural networks, import pretrained models from PyTorch, TensorFlow, and ONNX, and integrate trained networks into Simulink for system-level simulation. Artificial intelligence is not treated as a separate development activity. Neural network behavior can be simulated and verified together with the battery control model. Networks can also be optimized through quantization, projection, or pruning, and prepared for embedded deployment through automatic code generation. This reduces integration risk and makes AI-based BMS functions easier to validate within the complete system. For more information, see the Deep Learning Toolbox documentation in the References chapter. 2.2 Vehicle Network Toolbox Vehicle Network Toolbox brings CAN communication into the model-based workflow. It provides MATLAB functions and Simulink blocks for sending, receiving, encoding, and decoding CAN messages, making network behavior visible and testable before deployment. In the Battery Management System, commands, feedback, and status information are exchanged over CAN, linking the ECU with the surrounding vehicle architecture. The toolbox helps define signal interfaces, pack and unpack CAN messages, simulate bus traffic, and validate communication before target execution. Communication is not treated as a late integration step. CAN interaction can be simulated and verified together with the control model. This reduces integration risk and makes ECU behavior easier to validate end to end. For more information, see the Vehicle Network Toolbox documentation in the References chapter. 2.3 NXP Model-Based Design Toolbox for BMS The NXP Model-Based Design Toolbox for BMS extends the NXP Model-Based Design Toolbox for S32K3 with BMS support. It enables configuration and integration of the MC33775A, MC33774A, MC33772C, MC33665A, and MC33664. The S32K3 toolbox includes peripheral blocks that provide access to key microcontroller resources such as ADC, PWM, CAN, SPI, UART, timers, and interrupts. These interfaces facilitate communication between the S32K3 microcontroller and the supported BMS integrated circuits. Together, the toolboxes support the development and deployment of BMS applications on the S32K3 platform, leveraging the underlying S32K3 and BMS software stack. The workflow also integrates with NXP configuration tools and supports real-time monitoring and visualization through FreeMASTER, simplifying application development, validation, and debugging. 3 Hardware The central hardware platform is the 800 V Battery Management System Reference Design using ETPL. The kit contains: RD-K358BMU - Battery Management Unit RD33774CNTEVB - Cell Monitoring Unit RD772BJBTPL8EVB - Battery Junction Box BATT-18EMULATOR - 18-cell battery pack emulator 3.1 RD-K358BMU The RD-K358BMU is an NXP reference Battery Management Unit (BMU) designed for evaluation, development, and rapid prototyping of 800 V high-voltage Battery Management System (HVBMS) hardware and software. It provides a representative automotive-grade BMU platform built around the S32K358 microcontroller, enabling developers to evaluate battery-management architectures, safety concepts, communication interfaces, diagnostics, and control strategies in a realistic system environment. The board integrates several NXP components, including the S32K358, FS26, MC33665A, HB2000, TJA1145A, PCA2131, NBP8 and MC12XS6. Together, these components provide the processing, power management, communication, sensing, actuation, diagnostics, and safety capabilities required in a high-voltage BMS application. 3.2 Cell Monitoring Unit: MC33774A The RD33774CNT3EVB is a centralized Cell Monitoring Unit (CMU) reference design intended for the development and evaluation of 800 V high-voltage Battery Management System (HVBMS) applications. It uses Electrical Transport Protocol Link (ETPL) communication to connect with the broader BMS architecture and support reliable data exchange within the battery system. The board includes three MC33774 Analog Front End (AFE) devices arranged in a daisy-chain configuration. These AFEs are responsible for measuring and monitoring battery cell parameters, helping developers evaluate cell supervision, diagnostics, and communication strategies in a centralized BMS topology.   3.3 Battery Junction Box: MC33772C The RD772BJBTPL8EVB is a Battery Junction Box (BJB) reference design developed for 800 V high-voltage Battery Management System (HVBMS) applications. It leverages Electrical Transport Protocol Link (ETPL) communication to ensure robust and isolated data exchange within the battery system. The board features two MC33772C battery sensor ICs configured to deliver redundant measurements of voltage and current, improving diagnostic coverage and supporting functional safety requirements. It also performs isolation measurements, which are essential for monitoring insulation integrity and detecting potential fault conditions in high-voltage environments. 3.4 18-Cell Battery Pack Emulator The BATT-18EMULATOR board is designed to emulate a multi-cell battery pack and is easily interfaced with MC33774 battery cell controller evaluation boards. It enables quick evaluation of NXP Battery Cell Controller (BCC) ICs and supports software development by providing a controlled and flexible test environment. The board allows users to intuitively adjust the voltage of each of the 18 emulated cells, as well as the voltage levels on selected analog inputs typically used for temperature sensing. This capability makes it particularly useful for validating measurement accuracy, system behavior, and control algorithms without requiring a physical battery pack. Additionally, the BATT-18EMULATOR provides three independent outputs, allowing up to three BCC ICs to be connected simultaneously to a single emulator board. 4 References Deep Learning Toolbox Documentation Vehicle Network Toolbox Documentation NXP Model-Based Design Toolbox 800 V Battery Management System Reference Designs Using ETPL 5 Conclusion This article described the software and hardware environment required for the Battery Management System. The software combines MathWorks model-based design capabilities with NXP BMS and S32K3 platform support. The hardware integrates the S32K3 with NXP battery-cell controllers, communication interfaces, and associated BMS devices. Together, these elements provide the foundation for battery monitoring, communication, algorithm development, code generation, deployment, and validation.

让我们使用 S32K – RTD（首款车规级 MCU）运行一个 LED 闪烁应用程序（日本博客） 这篇文章是关于什么的？ 在上一篇文章中，我们安装了S32 设计工作室（以下简称S32DS ）和实时驱动程序（以下简称RTD），以执行使用 S32 MCU 进行评估和开发所需的必要准备步骤。 汽车级MCU S32K入门指南——开发环境搭建指南：安装S32DS和RTD（日语博客） 这一次，我们将迈出下一步，实际打开一个 RTD 示例项目，并通过生成代码、构建和调试来体验 S32K3 开发的“第一步” 。 本文目标：调试 S32K3 FRDM 板上的 RTD 示例 ， 并使 LED 闪烁（预计时间：15 分钟） 准备 硬件： FRDM-A-S32K344 USB Type-C 数据线（※FRDM-A-S32K344 随附） 在本文中， 我们将使用 FRDM Automotive 的 新型 开发板 FRDM-A-S32K344 ，该开发板采用 S32K3 微控制器。S32K344 是 一款 1x LockStep Arm Cortex-M7 微控制器， 广泛应用于 电机控制 和车身控制 等领域。 软件： S32DS（IDE 开发环境） RTD（S32K3软件） 请事先确保已安装上一篇文章中介绍的 S32DS和RTD 。 步骤 1：打开 RTD 样品 启动 S32DS 并创建一个新项目。然后，按照以下步骤打开 RTD 示例。 打开左下角的“ S32DS 项目示例”，然后点击“ S32K3XX 实时驱动程序… ”查看ADC 、 CAN 、 GPT 、 I2C 、 PWM 等示例。 这次，我们以“ Dio 示例”为例。 点击“Dio 示例”，然后 选择“ Dio_Example_S32K344 ”。 示例的详细信息会显示在右侧，请检查内容并 点击“完成”。 在左侧的“项目资源管理器”中导航到 main.c ，然后单击打开源代码。 您会在右下角和代码中看到几个“警告”，但这些警告并不表示源代码本身存在错误，而是表示S32DS没有正确找到与 RTD 相关的头文件。 步骤 2：解决警告 要解决此警告，请先单击屏幕左侧项目资源管理器中的“example_Dio.mex” 。 “example_Dio.mex”是一个存储MCU设置（例如，DIO = 数字I/O）、引脚/时钟/外设设置和代码生成设置的文件。 配置工具界面将会出现。点击顶部中央的“更新代码”按钮，即可更新代码并解决错误。更新完成后，右下角“问题”部分中的警告信息将会消失。   步骤 3：构建 点击下方按钮返回上一屏幕。 在项目资源管理器的“生成”部分，您可以查看每个软件及其各自的标题。 最后，点击屏幕左上角的构建按钮。屏幕右下角应该会显示“构建完成”的消息，确认没有错误后，就表示之前提到的警告问题已经解决。 到目前为止，我们已经确认可以打开 RTD 示例项目，从 .mex 文件生成代码，并成功完成构建。 第四步：调试 使用随附的USB Type-C 数据线将 FRDM-A-S32K344 连接到您的电脑。连接成功后，板上的 LED 指示灯将亮起。   返回 S32DS 屏幕，点击屏幕顶部中央的调试图标（虫子图标）开始调试。点击后，屏幕上会显示一条消息，提示您启动 PE Micro 调试器，请允许其启动，并按照屏幕上的说明进行调试。 PE Micro是一款用于调试的调试驱动程序（工具）。S32DS使用名为 PE Micro的调试器将开发板连接到PC。 在当前环境下， S32DS （ IDE ）➡ PE Micro（调试工具） ➡ FRDM-A-S32K344 这是我们沟通的渠道。 调试后，如果控制台中出现“目标已复位”和“ DAP 已成功上电”等日志，并且调试视图中显示线程信息（线程 #1），则表示与目标板的连接和程序传输已成功完成。   步骤五：点亮LED灯 现在，让我们在 FRDM-A-S32K344 板上实际检查一下。 点击屏幕中央工具栏中的播放图标 ▶ “恢复/运行” 以开始执行程序。 请注意，每个示例程序都在 main() 函数的开头设置了一个断点，以便于调试。 如果您能确认 LED 灯 亮起 几秒钟 （下图黄色圆圈中的 LED 灯），则此调试成功。 在这个示例代码中， 我们被指示“ while (count++ < 10) ”。 初始计数为0 每次循环迭代，计数都会增加count++。 仅当计数小于 10 时才有效 换句话说，LED 最多亮 10次才能完成操作，所以LED 只亮几秒钟然后停止是正常的。 到目前为止，我们已经体验了从构建和调试 RTD 示例项目到验证其在实际电路板上的运行（打开和关闭 LED）的整个过程。 最后 这一系列步骤代表了使用 S32K3 的基本开发步骤。 代码生成 → 构建 → 调试 → 测试功能 通过在电路板上实际观察其运行情况，你就能更直观地了解软件如何控制硬件。 根据这些基本步骤，尝试开发你自己的应用程序。 =========================​ 我们目前无法 回复 此帖子“ 评论”部分留下的评论。 对于由此造成的不便，我们深表歉意，但 在进行咨询时， 请 参考“ NXP 技术问题 - 如何联系我们 （ 日语博客 ） ” 。 （如果您已经是 恩智浦的 分销商或 与 恩智浦 有合作关系 ，您可以直接咨询您的代表。） 在本文中，我们将使用 S32K3 实时驱动程序中的一个 LED 闪烁示例项目，通过生成、构建和调试代码来体验 S32K3 开发的“第一步”。 本文目标：调试S32K3 FRDM 板上的RTD示例并使其 LED闪烁。 （预计时间：15分钟） 通用微控制器 S32设计工作室 S32K SW | 下载 日本博客

Let's run an LED blinking application using the S32K – RTD, the first automotive-grade MCU (Japanese blog) What is this article about? In the previous article, we installed S32 Design Studio (hereinafter S32DS ) and Real-Time Driver (hereinafter RTD) to perform the necessary preliminary steps for evaluating and developing with the S32 MCU. First Steps with the Automotive MCU S32K – Development Environment Setup Guide: Installing S32DS and RTD (Japanese Blog) This time, as the next step, we will actually open an RTD sample project and experience the " first step " of S32K3 development by generating code, building, and debugging . Goal of this article: Debug a sample from RTD on an S32K3 FRDM board and make an LED blink (estimated time: 15 minutes) Preparation Hardware: FRDM-A-S32K344 USB Type-C cable (※Included with FRDM-A-S32K344) In this article, we will be using the new FRDM Automotive board, the FRDM-A-S32K344 , which uses the S32K3. The S32K344 is a 1x LockStep Arm Cortex-M7 microcontroller and is used in a wide range of applications, including motor control and body control . software: S32DS (IDE development environment) RTD (Software for S32K3) Beforehand, please make sure that S32DS and RTD, which were introduced in the previous article , are installed. Step 1: Open the RTD sample Launch S32DS and create a new project. Then, follow these steps to open the RTD sample. Open " S32DS Project from Example " in the lower left corner, and click " S32K3XX Real-Time Drivers… " to see examples of ADC , CAN , GPT , I2C , PWM, etc. This time, let's use " Dio Example " as an example. Click on "Dio Example," and then select " Dio_Example_S32K344 " from there. The details of the example are displayed on the right, so check the contents and click "Finish." Navigate to main.c in the "Project Explorer" on the left and click to open the source code. You will see several "Warnings" in the bottom right and on the code, but these warnings do not indicate errors in the source code itself, but rather that S32DS is not correctly finding where to look for RTD-related header files. Step 2: Resolving the Warning To resolve the warning, first click on "example_Dio.mex" in the Project Explorer on the left side of the screen. "example_Dio.mex" is a file that stores MCU settings (e.g., DIO = Digital I/O), Pins/Clock/Peripheral settings, and code generation settings. The Configuration Tool screen will appear. Click "Update Code" at the top center to update the code and resolve the error. Once the update is complete, the warning message will disappear from the "Problem" section at the bottom right.   Step 3: Build Click the button below to return to the previous screen. In the " generate " section of Project Explorer, you can view each software and its respective headers. Finally, click the build button in the upper left corner of the screen. You should also see a "Build Finished" message in the lower right corner of the screen, and confirm that there are no errors, which means the warning mentioned earlier has been resolved. Up to this point, we have confirmed that we can open the RTD sample project, generate code from the .mex file, and complete the build successfully. Step 4: Debugging Connect the FRDM-A-S32K344 to your PC using the included USB Type-C cable . The LED on the board will light up when the connection is successful.   Return to the S32DS screen and click the debug icon (bug logo) at the top center of the screen to start debugging. After clicking, a message will appear asking you to launch the PE Micro debugger, so allow it to launch and follow the on-screen instructions to proceed with debugging. PE Micro is a debug driver (tool) used by the S32DS to connect the board to the PC. In the current environment, S32DS ( IDE ) ➡ PE Micro ( Debugging Tool ) ➡ FRDM-A-S32K344 This is the route through which we are communicating. After debugging, if logs such as " Target has been RESET " and " DAP successfully powered up " appear in the Console, and thread information ( Thread #1 ) is displayed in the Debug view, then the connection to the target board and program transfer have been completed successfully.   Step 5: Light up the LED Now, let's actually check it on the FRDM-A-S32K344 board. Click the play icon ▶ “Resume/Run” in the toolbar in the center of the screen to start the program execution. Please note that each sample program has a breakpoint placed at the beginning of the main() function to facilitate debugging. If you can confirm that the LED lights up for a few seconds (the LED circled in yellow in the diagram below), then this debugging was successful. In this example code, we are instructed to " while (count++ < 10) ". Start with count = 0 The count increases by count++ with each loop iteration. It only works while count < 10 In other words, the LED lights up a maximum of 10 times to complete the operation, so it's normal for the LED to light up for only a few seconds and then stop . Up to this point, we have been able to experience the entire process from building and debugging the RTD sample project to verifying its operation on the actual board ( turning the LEDs on and off). Finally This series of steps represents the basic development steps using the S32K3. Code generation → Build → Debug → Test functionality By actually seeing it in action on the board, you were able to gain a more intuitive understanding of how software controls hardware. Based on these basic steps, try developing your own application. =========================​ We are currently unable to respond to comments left in the " Comment " section of this post .

初めての車載向けMCU S32K – RTDを使用してLED点滅のアプリケーションを動かしてみよう (日本語ブログ) この記事は？ 前回の記事では、S32 Design Studio（以下S32DS）とReal-Time Driver（以下RTD）のインストールを行い、S32 MCUの評価、開発に必要な下準備を行いました。 初めての車載向けMCU S32K – 開発環境構築ガイド：S32DSとRTDのインストール（日本語ブログ） 今回はその次のステップとして、実際にRTDのサンプルプロジェクトを開き、コード生成、ビルド、デバッグを行うことで、S32K3開発の「最初の一歩」を体験してみます。 この記事のゴール：S32K3 FRDMボード上でRTD内のサンプルをデバッグし、LEDを点滅させる （所要時間：15分） 事前準備 ハードウェア： FRDM-A-S32K344 USB Type-Cケーブル (※FRDM-A-S32K344に付属しています。) 今回の記事では、S32K3の新しいFRDM Automotiveボード、FRDM-A-S32K344を使います。S32K344は、１ｘLockStep Arm Cortex-M7 マイクロコントローラで、モーター制御、ボディ制御等、幅広いアプリケーションで採用されています。 ソフトウェア： S32DS (IDE開発環境) RTD (S32K3用ソフトウェア) 事前に、前回の記事、で紹介したS32DSとRTDがインストールされていることを確認してください。 ステップ１：RTDサンプルを開く S32DSを起動し、新しいプロジェクトを作成しましょう。その後、以下の手順に沿って、RTDサンプルを開きます。 左下の「S32DS Project from Example」を開き、「S32K3XX Real-Time Drivers…」をクリックすると、ADC、CAN、GPT、I2C、PWM…etc.等のサンプルが確認できます。 今回は、例として「Dio Example」を使ってみましょう。「Dio Example」をクリックし、その中からさらに「Dio_Example_S32K344」を選択。右側に、Exampleの詳細が記載されているため、中身を確認し、「Finish」をクリック。 左の「Project Explorer」でmain.cへと移動し、クリックすると、ソースコードを開くことができる。 右下およびコード上にいくつかの「Warning」が表示されますが、この警告は、ソースコードそのもののミスではなく、S32DSがRTD関連のヘッダファイルを探す場所を正しく見つけられていない場合に表示されます。 ステップ２：Warningの解消 Warningを解消するために、まずは画面左のProject Explorerから、「example_Dio.mex」をクリックします。「example_Dio.mex」は、MCUの設定（例：DIO = Digital I/O）、Pins / Clock / Peripheral設定、コード生成設定情報を保存しているファイルです。 Configuration Toolの画面が表示されるので、中央上の「Update Code」をクリックし、エラーを解消するためにコードを更新します。アップデートが完了すると、右下の「Problem」セクションからWarningメッセージが消えます。   ステップ３：ビルド 以下のボタンをクリックし、元の画面に戻ります。 Project Explorerの「generate」のセクションで、各ソフトウェアとそれぞれのヘッダーを確認することができます。 最後に、画面左上のビルドボタンをクリックします。画面右下に「Build Finished」のコメントともにエラーが無いことも確認できるので、先ほどのWarningも解消されたことが確認できます。 ここまでで、RTDサンプルプロジェクトを開き、.mexファイルからコードを生成し、ビルドが正常に完了するところまで確認できました。 ステップ４：デバッグ FRDM-A-S32K344を付属のUSB Type-Cケーブルを使って、お使いのPCにつないでください。正常につながると、ボード上のLEDが光った状態になります。   S32DSの画面に戻り、画面中央上のデバッグアイコン（虫のロゴ）をクリックし、デバッグを開始しましょう。クリックすると、デバッガのPE Microを起動させるメッセージが出てくるので、起動を許可し、画面の指示に沿ってデバッグを進めてください。 PE Micro は、デバッグ用の接続ドライバ（ツール）で、S32DSがPCとボードをつなぐために、PE Microというデバッガを使っています。 現在の環境では、 S32DS（IDE）➡ PE Micro(デバッグツール) ➡ FRDM-A-S32K344 という経路で通信しています。 そして、デバッグ実行後、Consoleに「Target has been RESET」「DAP successfully powered up」などのログが表示され、さらにDebugビューにスレッド情報（Thread #1）が表示されていれば、ターゲットボードへの接続およびプログラム転送は正常に完了しています。   ステップ５：LEDを光らせる では、実際にFRDM-A-S32K344ボード上で確認しましょう。 画面中央のツールバーにある再生マーク ▶ “Resume/Run”をクリックすると、プログラム実行がスタートします。 尚、各サンプルプログラムはデバッグを行いやすいように、main()の先頭にブレイクポイントを貼っています。 「数秒だけLEDが光る」（下図の黄色で囲ったLED）動作が確認できれば、今回のデバッグは成功です。 今回のDim Exampleのコードでは、“while (count++ < 10)”と指示されており、 count = 0 でスタート ループ1回ごとに count++ で増える count < 10 の間だけ動く つまり、最大10回LEDが光って動作が完了する、という中身になっているため、LEDが数秒だけ動作して止まるのが正常な挙動です。 ここまでで、RTDサンプルプロジェクトのビルドからデバッグ、そして実機ボード上での動作確認（LEDの点灯・消灯）までを一通り体験することができました。 さいごに 今回の一連の流れは、S32K3を用いた開発の基本ステップとなります。 コード生成 → ビルド → デバッグ → 動作確認 実際にボード上で動作を確認することで、ソフトウェアがハードウェアを制御していることをより直感的に理解できたのではないでしょうか。 この基本ステップをベースに、ご自身のアプリケーション開発へと発展させてみてください。 =========================​ 本投稿の「Comment」欄にコメントをいただいても、現在返信に対応しておりません。​ お手数をおかけしますが、お問い合わせの際には「NXPへの技術質問 - 問い合わせ方法 (日本語ブログ)」をご参照ください。​ （既に弊社NXP代理店、もしくはNXPとお付き合いのある方は、直接担当者へご質問いただいてもかまいません。） 今回の記事では、S32K3 Real-Time Driver内のLED点滅のサンプルプロジェクトを用いて、コード生成、ビルド、デバッグを行うことで、S32K3開発の「最初の一歩」を体験します。 この記事のゴール：S32K3 FRDMボード上でRTD内のサンプルをデバッグし、LEDを点滅させる （所要時間：15分） General Purpose Microcontrollers S32 Design Studio S32K SW | Downloads 日本語ブログ

S32K312 POR_WDG is what, how to use. Hi HXP, S32K312 POR_WDG is what, how to use. Re: S32K312 POR_WDG is what, how to use. Hi @li3, 1. Please refer to the DCF clients file attached to the reference manual. 2. The Watchdog timer has a configurable threshold, if the chip does not exit the reset sequence within this time, the POR_WDG initiates a power-on-reset. You can monitor the WDG status from the DCMROPPn register.  3. This register only captures the status of the functional reset sequence process when POR_WDG overflows. Since the POR_WDG is part of the DCF client safety function, you can also look into the Safety Manual for S32K3 in "Secure Files" from the S32K3 Auto General-Purpose MCUs, documentation. Best regards, Julián Re: S32K312 POR_WDG is what, how to use. Hi NXP,     Please help me answer the following three questions.     1.I can't find the control register for reset monitor. I don't know how to turn on or off the reset monitoring function of POR_WDG. Please tell me the location of the register.     2. How does the reset monitoring function detect that the system is stuck in the reset sequence? Does it detect registers that have not been successfully reset?     3.The reset monitoring function indicates that after POR_WDG times out, the system deadlock position can be captured in DCM's DCMROPPn register. Can these states only let us know the system deadlock position after POR_WDG times out? Or is it the state of DCM's DCMROPPn register that determines the POR_WDG timeout? Best regards, Li 3. Re: S32K312 POR_WDG is what, how to use. Hi @li3, This is in case of functional reset event: Best regards, Julián Re: S32K312 POR_WDG is what, how to use. Hi NXP, What is the Reset monitoring control register? Is it to monitor whether Reset can succeed? Best regards, Li 3. Re: S32K312 POR_WDG is what, how to use. Hi @li3, The Power-on Reset Watchdog is a module for added monitoring to the chip. If the chip is stuck in reset or standby for a determined time, the watchdog generates a power-on reset to recover it.  Best regards, Julián

SL3S1013FTB0,115 design check request 1) Is the transponder schematic above correct for a 3.6V-powered and RFID-powered configuration?   2) Is the voltage stated correct for a 3.6V-powered and RFID-powered configuration for the RFID transponder?   a) 2.6V - 3.1V (3.6V powered) b) 1 - 1.5V (RFID powered) Re: SL3S1013FTB0,115 design check request Your supply voltage correction has been received. I will make the correction.  Your question: Is this the intended purpose for your application? Answer: We don't have an application for the current product, but we want to understand how this tamper alarm works.  I calculated the Vout for 1.8V and 2.2 V. Is this calculation correct? If yes, the Vout is too low to do anything meaningful. Vout = Ivdd X 1k Ivdd = Iinternal +Iout The typical, permanent current consumption will be ~120 µA for 1.8V and ~340 µA for 2.2V. For VDD = 1.8 V, Idd = 0.00012A For VDD = 2,2 V, Idd = 0.00034A For VDD = 1.8 V, Vout =  0.00012 X 1kohm Vout = 0.12V For VDD = 2.2 V, Vout =  0.00034 X 1kohm Vout = 0.34V Re: SL3S1013FTB0,115 design check request Hello @pragashsangaran When externally supplied, VDD pad requires a voltage between 1.8V and 2.2V; for a higher value, a series resistance would be required. For proper calculation, please refer to AN10940 FAQs on UCODE G2i, Chapter 3/Chapter 4. OUT pad is a digital output that can be used for tamper loop, a small external circuit or as indicator; these configurations require VDD pin to be externally suppled. If you populate R35, it will introduce a connection that could activate the "tamper indicator" bit, as per Tag Tamper Alarm feature (please see AN10940 FAQs on UCODE G2i, Chapter 16). Is this the intended purpose for your application? Expected voltage level on OUT pin is described in AN10940 FAQs on UCODE G2i, Chapter 13. A solution that powers a device connected to OUT pin requires an external supply on VDD pin. I will recommend you taking a look at the AN11237 UCODE G2iM+ demo board documentation, Fig 3 and Fig 5 for some reference connections. Regards, Eduardo. Re: SL3S1013FTB0,115 design check request Hi, In order to use the OUT pin functionalities, such as digital output/switch or powering an external circuit, an external supply is required. Also, as mentioned in AN10940 FAQs on UCODE G2i, Chapter 16 "How is the Tag Tamper Alarm used?" this feature is based on a galvanic connection between VDD and OUT; something important to remark is that the tamper feature and the external supply mode cannot be used at the same time. Regarding the calculations, please consider that the voltage level available on the OUT pin is defined by the voltage level on VDD reduced by the voltage drop on the internal series resistor. You can find a few examples on AN10940 FAQs on UCODE G2i, Chapter 5.3. Regards, Eduardo. Re: SL3S1013FTB0,115 design check request EduardoZamora, thank you so much. After many attempts to ask the same questions again and again, I finally feel like I im getting the correct answers to my questions. I really hope we can resolve my question in this ticket.  I also want to know if it is the Vout of the RFID-powered configuration (without VDD). Can you please let me know as well?  im not using a tamper indicator. I hope we can justify the use of SL3S1013FTB0,115 vs a Schottky diode. If a Schottky diode can provide higher Vout without a supply voltage, I'd rather go for a Schottky diode.  Re: SL3S1013FTB0,115 design check request Hi, Vout depends on the voltage present on VDD pin (after proper dimensioning of the series resistor between VDD and RFN according to AN10940 FAQs on UCODE G2i, Chapter 5), reduced by the voltage drop on the internal series resistor between VDD and OUT (~1kΩ). Some calculation examples can be found in Chapter 5.3. Regarding the state of OUT pin, please refer to Chapter 8 to 10 for more information on how to control this pin. Regards, Eduardo. Re: SL3S1013FTB0,115 design check request Hi  EduardoZamora, We are not going to use Tamper Alarm, so we can ignore this. The R35 is there just in case. For us, Vout is very important because it needs to turn the product ON. You are saying VDD needs to be present in order to get Vout. However, I have two major concerns about using this part. The calculated Vout is too low. For VDD = 1.8 V, Vout = 0.12V For VDD = 2.2 V, Vout = 0.34V. This Vout will not help at all to turn things on . Even if we think about boosting this voltage, there aren't many options available to raise it further. Is my calculation correct? Please see one of my previous replies for full calculations. In the presence of VDD, can Vout be present regardless of the RFID signal? We want Vout to be present only when the antenna receives an RFID signal. Is this true?

GUI Guider 1.10.1 omits background style properties when Background Opacity is 0 Environment GUI Guider: 1.10.1 LVGL: 8.3 Widget: Button Style Part: LV_PART_MAIN Style State: LV_STATE_DEFAULT Problem Description I found a reproducible code-generation issue in GUI Guider 1.10.1. When a button has a configured background color but its Background Opacity is set to 0, GUI Guider does not generate the corresponding background color property. This causes unexpected behavior when the background opacity is changed dynamically at runtime. Reproduction Create a Button and configure: Background Color: #F08300 Background Opacity: 0 Then generate the LVGL 8.3 code. GUI Guider generates: lv_obj_set_style_bg_opa(ui->screen_password_btn_15, 0, LV_PART_MAIN | LV_STATE_DEFAULT); However, the configured background color is not generated: lv_obj_set_style_bg_color(ui->screen_password_btn_15, lv_color_hex(0xF08300), LV_PART_MAIN | LV_STATE_DEFAULT); Test: Change only Background Opacity from 0 to 1 I changed only the Background Opacity from 0 to 1, while keeping the same Background Color #F08300. After regenerating the code, GUI Guider generates: lv_obj_set_style_bg_opa(ui->screen_password_btn_15, 1, LV_PART_MAIN | LV_STATE_DEFAULT); lv_obj_set_style_bg_color(ui->screen_password_btn_15, lv_color_hex(0xF08300), LV_PART_MAIN | LV_STATE_DEFAULT); lv_obj_set_style_bg_grad_dir(ui->screen_password_btn_15, LV_GRAD_DIR_NONE, LV_PART_MAIN | LV_STATE_DEFAULT); Therefore, the generated code differs depending on whether Background Opacity is exactly 0. Background Opacity = 0: bg_opa is generated bg_color is not generated Background Opacity = 1: bg_opa is generated bg_color is generated other background properties are also generated Runtime Impact My application uses the background opacity to indicate the currently selected password digit. The background color is configured in GUI Guider as #F08300, while the application dynamically changes only the background opacity. For example: lv_obj_set_style_bg_opa(btn, LV_OPA_COVER, LV_PART_MAIN | LV_STATE_DEFAULT); For a button whose initial Background Opacity is 0, the generated code does not contain the configured background color. When the application changes the opacity from 0 to LV_OPA_COVER, the button displays the LVGL theme or default background color instead of the #F08300 color configured in GUI Guider. The behavior is: GUI Guider configuration: Background Color = #F08300 Background Opacity = 0 Generated code: bg_opa = 0 bg_color is not generated Runtime: bg_opa is changed to LV_OPA_COVER Result: The default or theme background color is displayed instead of #F08300. Workaround Explicitly setting the background color in application code resolves the issue: lv_obj_set_style_bg_color(btn, lv_color_hex(0xF08300), LV_PART_MAIN | LV_STATE_DEFAULT); lv_obj_set_style_bg_opa(btn, LV_OPA_COVER, LV_PART_MAIN | LV_STATE_DEFAULT); Another possible workaround is setting Background Opacity to 1 in GUI Guider, because this causes GUI Guider to generate the configured background color. However, this changes the initial UI state and is therefore not ideal. Expected Behavior Background Color and Background Opacity are separate LVGL style properties. If the user explicitly configures: Background Color = #F08300 Background Opacity = 0 I would expect GUI Guider to preserve both properties in the generated code: lv_obj_set_style_bg_opa(btn, 0, LV_PART_MAIN | LV_STATE_DEFAULT); lv_obj_set_style_bg_color(btn, lv_color_hex(0xF08300), LV_PART_MAIN | LV_STATE_DEFAULT); Although bg_color has no visible effect while bg_opa is 0, it becomes relevant when the application dynamically changes bg_opa at runtime. The current code-generation behavior loses the background color information configured in GUI Guider. Actual Behavior GUI Guider 1.10.1 appears to omit background style properties when Background Opacity is 0. Changing only the opacity from 0 to 1 causes the background color and other background properties to be generated again. Steps to Reproduce Create a Button in GUI Guider 1.10.1. Set Background Color to #F08300. Set Background Opacity to 0. Generate LVGL 8.3 code. Observe that lv_obj_set_style_bg_opa with value 0 is generated. Observe that lv_obj_set_style_bg_color with #F08300 is not generated. Change only Background Opacity from 0 to 1. Generate the code again. Observe that lv_obj_set_style_bg_color with #F08300 is now generated. At runtime, change the opacity of the original button to LV_OPA_COVER. Observe that the configured background color is not displayed unless bg_color is explicitly set by the application. Question Is this an intentional code-size optimization in GUI Guider 1.10.1, or is it a code-generation issue? If this optimization is intentional, could GUI Guider provide an option to preserve background properties when Background Opacity is 0? Runtime applications commonly change LVGL style properties dynamically, so omitting bg_color based only on its initial opacity can result in runtime behavior that differs from the UI configuration. Re: GUI Guider 1.10.1 omits background style properties when Background Opacity is 0 Hello @zzjgood , Thanks for your post.  I can reproduce the behavior you described. I think this is a code-generation issue. If the user explicitly configures a Background Color, GUI Guider should preserve the corresponding bg_color code even when the initial Background Opacity is 0, or provide an option to preserve background style properties for transparent objects. I will report this to the GUI-Guider team for further fix. In addition, according to our internal escalation process, we would appreciate it if you could provide the following information: - Which NXP product are you using? - What is your end application? The current practical workaround is to explicitly set both the background color and opacity in the application code: Copy lv_obj_set_style_bg_color(btn, lv_color_hex(0xF08300), LV_PART_MAIN | LV_STATE_DEFAULT); lv_obj_set_style_bg_opa(btn, LV_OPA_COVER, LV_PART_MAIN | LV_STATE_DEFAULT); Hop it helps.

PN512 - Does it actually support Type 4 Tag (T4T/HCE) card emulation? Hi all, Working on a custom board (LPC54101 + PN512) that needs to both read NTAG213/216 tags (working fine) and emulate a Type 4 Tag serving a static NDEF (BT-OOB pairing record) so a phone can tap and read it. Using NxpRdLib V2.0.3.0 with phpalI14443p4C_Sw / phceT4T_Sw. Calling phceT4T_Listen() in a loop -> internally phhalHw_Listen() -> Autocoll on the PN512. Consistently get PH_ERR_IO_TIMEOUT (0x0201), unaffected by timeout config, explicit FieldOff before listening, or register-level checks (TxControlReg confirms our own field is off, GsNOffReg at datasheet default, RFCfgReg/RxThresholdReg/DemodReg all normal). No reaction at all from Android or iPhone held directly on the antenna. I found this thread where NXP support says PN512 can't do card emulation per the datasheet, and recommends CLRC663 instead: https://community.nxp.com/t5/Other-NXP-Products/PN512-Emulation-Tag-Write-issue/m-p/2089993 But that seems to contradict the PN512 product page (lists "card emulation functionality" as a feature), and this other thread where someone got Mifare Ultralight tag emulation working fine on PN512: https://community.nxp.com/t5/NFC/Pn512-Tag-Emulation-Callibration/td-p/684135 So: is the difference that PN512 can do simple ISO14443-3 tag emulation (UID/anticollision, like Mifare UL) but NOT full ISO14443-4 Type 4 Tag activation (RATS/ATS, APDU exchange)? Has anyone gotten genuine T4T/HCE working on PN512, or is this chip a dead end for that specific use case? Also separately: our RdLib V2.0.3.0 package's ReleaseNotes.txt states the discovery loop only supports Poll/Pause phases, and the .chm docs have zero mention of phceT4T or phpalI14443p4C - so I'm also unsure whether the card-emulation component we have was ever an officially validated/documented release. Any pointers to a proper matching package appreciated. Thanks! Re: PN512 - Does it actually support Type 4 Tag (T4T/HCE) card emulation? Hello sir, As mentioned in your other case, yes PN512 does support HCE, we even have an example with Raspberry Pi. But please keep in mind that PN512 isn't recommended for new designs. Please explore the possibility of using our NFC Readers that are Full Support NFC mode (PN5190, PN5180, PN7462, PN7642).  All of these readers can be used with our NFC Reader Library. I hope this information may have been useful. Re: PN512 - Does it actually support Type 4 Tag (T4T/HCE) card emulation? Quick update for anyone finding this thread later, since I got two different answers between here and my support ticket: AN11480 (the Raspberry Pi/EXPLORE-NFC guide) only demonstrates Type 2 Tag emulation on PN512 - it says so directly in §7.1 ("the Card Emulation example emulates an NFC Forum Type 2 Tag") and never mentions phceT4T or T4T anywhere. If you were pointed there for T4T/HCE, that's not the right doc. For actual Type 4 Tag (T4T/HCE) emulation on PN512, see AN11308 (PNEV512B/LPC1769 Quick Startup Guide), §6.8 "Example 8 - HCE T4T" and §7.1.6 "HCE Layer". That example is explicitly built on the NFC Forum Type 4 Tag Operation Specification v2.0, using phceT4T_Activate()/phceT4T_AppProcessCmd(), and supports Select/ReadBinary/UpdateBinary. So: yes, PN512 does support genuine T4T emulation, just not via the Raspberry Pi package - via the PNEV512B/LPC1769 (Blueboard) package instead. Following up with support to confirm the exact library version and reconcile the two answers.

LIN communication failure during E-Flash write A LIN communication failure is detected during the write operation of 100 bytes of data to the internal EEPROM. Please suggest an appropriate LIN communication recovery method. Re: LIN communication failure during E-Flash write Hi @SivaB  Could you please let us know which exact S32K device you are using? One possible explanation is that the Emulated EEPROM operation takes a relatively long time, and the resulting delay may prevent the software from servicing LIN interrupts within the required timing constraints. Another possibility is a Read-While-Write conflict. During flash erase/program operations, code or data located in the flash block currently being programmed or erased cannot be fetched/read. If such code or data is required by the application, this could cause the application to crash, which would subsequently result in the observed LIN communication failures. Could you also clarify what happens when the issue occurs? Does the application crash completely, or does it continue running and only the LIN communication stop working? Regards, Lukas

IMX8MP Self Designed Board system crash after booting in the system Hi everyone, We designed a custom board using the i.MX8M Plus (IMX8MP) CPU with 4GB LPDDR4 RAM and 128GB eMMC storage. Below is our boot log. As you can see, after booting into Linux, we can briefly enter commands in the console, but the system freezes almost immediately and becomes completely unresponsive. We suspect this issue might be caused by the EXT4-fs error shown in the log. Has anyone encountered a similar issue, or could you give us some advice on how to troubleshoot this? Any help would be greatly appreciated! Thanks in advance.

S32DS LPSPI SLAVE 配置 S32K344 + 33664需要将LPSPI 配置成slave 模式。 S32DS SPI配置slave后，33664回完数据后， MCU如何取数据呢？ 需要调用哪些API？ Re: S32DS LPSPI SLAVE 配置 已经测试，使用 Lpspi_Ip_AsyncTransmit().可以收到数据.  我是想在 Lpspi_Ip_AsyncTransmit().的回调函数中继续调这个函数来触发接收第二帧33664回复的数据，但是由于MC33664 回复了两帧数据，两次CS之间间隔只有2.6us， Lpspi_Ip_AsyncTransmit().的回调函数来不及处理，导致第二次CS的数据没有收到，这个如何处理呢？ Re: S32DS LPSPI SLAVE 配置 你好@RRR123 建议使用 电池管理系统 SDK 中提供的 PHY_664 驱动程序进行 MC33664 通信。PHY_664 驱动程序专门设计用于管理与 MC33664 收发器的通信。 NXP电池管理软件开发工具包和工具链

Example code for K344 & FS26 with MCAL component Sbc_fs26 and OS component freeRTOS Hello, Can you provide a S32K344 & FS26 chips source code example (S32DS project) that integrates the Sbc_fs26 and freeRTOS components? I am aware that there are individual RTD examples: 1)  Sbc_fs26_example_HLD_S32K344  (no freeRTOS) 2) FreeRTOS_Toggle_Led_Example_S32K344 (no Sbc_fs26) and also an example: 3) MR_CANHUBK3_IEEE1722 in which the watchdog is disabled and the Sbc_fs26 component is not used  Essentially I'm looking for a basic source code example for properly setting and refreshing a FS26 chip in a freeRTOS environment. Thank you. Re: Example code for K344 & FS26 with MCAL component Sbc_fs26 and OS component freeRTOS Hello Slavko, At the moment, I am not aware of an example project combining these components.   The examples you mentioned are the relevant reference points: - Sbc_fs26_example_HLD_S32K344 This demonstrates the FS26/SBC integration, but it does not use FreeRTOS. - FreeRTOS_Toggle_Led_Example_S32K344 This demonstrates a basic FreeRTOS setup on S32K344, but it does not include the FS26 SBC component. - MR_CANHUBK3_IEEE1722 This includes a broader system-level implementation, but the FS26 watchdog is disabled and the Sbc_fs26 component is not used. For your use case, the practical approach would be to start from the Sbc_fs26_example_HLD_S32K344 project and then integrate the FreeRTOS configuration from the FreeRTOS example. The FS26 initialization should remain part of the system startup sequence, while the watchdog refresh should be handled periodically from a FreeRTOS task or another deterministic timing mechanism.   BRs, Tomas
