Question As we know, the TPPSDK supports S32K144 MCU and various Kinetis MCUs to initialize GD3000 in NXP MC solutions. Because of the release of S32K3 and related SW RTD, it’s necessary to expand the capability of TPPSDK to support S32K3 MC based RTD LLD driver or MCAL driver. Unfortunately, the AA team will not maintain the TPPSDK anymore.  How could we configure the GD3000 chip for S32K3 platform? JoaquinL_0-1662367122679.png   Answer I took some time to finish this work. Here I'd like to share you the The Expanded TPPSDK Based on S32K3 RTD that is suitable for S32K3 MC application. You can find the Application Note, the source code of new TPPSDK (GD3000 driver), two examples in the attachment. I hope these materials can help you get start with the expanded TPPSDK on S32K3.

           The hardware of this routine is based on S32K142EVB, the IDE is S32_Design_Studio for ARM 2018.R1, SDK version is S32K1xx_RTM_3.0.0, PTB12 is used to simulate Hall pulse output,PTC12 and PTC13 are buttons to change the flip frequency of PTB12 port, and PTB13 is used as the input capture port. When using the demo program in this article, you need to connect PTB12 and PTB13 ports.   Here we assume that we are using a brushed DC motor!   1.The Hall sensor       The Hall sensor is a magnetic induction sensor. The magnetic ring and the Hall element form an induction combination. The magnetic ring rotates with the rotor. The Hall induction magnetic ring rotates with the rotor. , 3-pole pairs, 4-pole pairs, etc., each pair of poles is divided into two levels of N.S. A pair of magnetic poles outputs one pulse signal, and multiple magnetic poles output multiple pulse signals. The number of magnetic pole stages determines the number of pulse signals. , the higher the accuracy. Senlent_0-1662085737184.png   Hall sensor 2.The relationship between the motor magnetic ring series and the output Hall waveform Senlent_8-1662086039398.png 5 pole pairs 3.Determination of motor rotation direction         The direction of the motor is judged by the phase difference of the two Hall signals. As shown in the figure below, the phase of Sensor A is ahead of Sensor B, so it can be considered that the current rotation direction of the motor is clockwise. Senlent_10-1662086562701.png   Senlent_11-1662086608861.png 4.Calculation of motor speed         The speed of the motor can be calculated by the pulse width of the pulse, and the number of revolutions of the motor can be calculated by the number of pulses. Assuming that the Hall magnetic ring of the motor has 5 pairs of poles, it means that there are five pulses in one revolution of the motor, and the speed of the motor = 60 / (t1 * 5) rev/min. The number of pulses can be obtained by the edge capture function of the FTM. Senlent_12-1662086894216.png Motor speed and stroke         Assuming that the clock of the FTM is 2MHz, then it takes 1/2000000 seconds for the counter to add 1. Since the unit of the motor speed is rpm, the calculation formula of the motor speed is : -> Motor Speed = 60 / (5 * a* (1 / 2000000))         In this formula, '5' is the number of pole pairs of the magnetic ring, and 'a' is the difference of the counter corresponding to the falling edge of two consecutive pules.         Let’s do a test, the square wave in the below figure is the outputs of PTB12, and the output pulse period is 32.1ms. Then the time required for the motor to rotate once should be:32.1ms *5 = 160.5ms, then the speed of the motor should be: 60 * 1000 / 160.5 = 373.83rpm.   Senlent_13-1662087020061.png PTB2 output square wave          The below picture is directly obtained by the debugger. It can be seen that the speed of the motor at this time is 373, which is not much different from the value measured by the oscilloscope, which is 373.83. This is because I did not use the floating-point calculation result in the program. In summary, we use the input capture function of the FTM module completes the calculation of the motor speed. Senlent_14-1662087152239.png   debuger monitor results 5.How to calculate the direction of rotation of the motor         Above we calculated the speed of the motor, but did not make judgement on the direction of the rotation of the motor. As mentioned above, the rotation direction of the motor is judged by the phase difference of the two Hall pulse waveforms. Usually, we think of using the timestamp to judge the current state of the phase, so we will enable the two input captures, and then calculate the two Halls timestamp of the falling edge of the pulse.         In fact, there is a simpler method, it only needs to read the high and low state of the other Hall pulse level when the falling edge of one hall pulse is interrupted. In short, we only need to enable one input capture, and the other to be used as a GPIO port.

Symptoms Recently found the compatibility issue is a troublesome problem especially when we are supporting different version of RTD. Remove/install the RTD SDK and plug, but it is not a perfect way because reinstall the RTD would cause a lot of time, sometimes it is unreliable. Diagnosis After investigated the mechanism of CT and MEX file, and found a work around to let the old project can be run in new version of RTD basis. Solution Already tested it with several reference code and examples of RTD, it can work. Attached is the document.

This article is written in Chinese. It is mainly for the disty and mass market customers in local China. It is useful for the the developers who is newly in touch with S32K1, and will help them install several software of S32K1, otherwise it may waste a lot of time.     S32DS中快速搭建S32K1的开发环境 一．背景 我最近换装了新电脑，需要重新安装S32DS，发现存在很多问题。尤其是对比之前的安装过程，发现官网的很多链接已经失效，甚至有一定的迷惑性。 最新的S32K1安装包比较隐蔽，而且安装存在前后依赖，对于刚接触NXP S32系列的新手非常不友好，所以写这篇文档总结一下典型的问题和解决方法。 同时也希望提供一个check的思路和步骤，在后续新版本发布时，升级IDE的时候更方便找到合适的安装包。 二．S32DS中各个包依赖关系解析 在S32DS中，每一个系列的MCU，总共需要安装两个插件包，一个是基础依赖包，一个是SDK（也叫RTD，同一个意思）。 1．基础依赖包 这个包对应S32DS版本，比如当前的3.4.3，官网可以下载离线版，一般大小在3GB左右，会更新S32DS中的很多组件，如下图1所示： LiekLi_9-1655884629244.png            图1 尤其需要关注图1中红框的内容，没有这个development package的话，是无法进行对应MCU的debug。 图1中安装的包，对应到S32DS中安装的内容如图2所示： LiekLi_10-1655884629307.png            图2 2．RTD安装包（与SDK同义） 这个包对应于RTD版本，也会标识AutoSAR的版本，比如最新的2.0.0，AutoSar 4.4，如图3所示： LiekLi_11-1655884629325.png           图3 基础依赖包与RTD安装包存在前后依赖关系，如果不安装基础依赖包直接安装RTD，在安装时会报错。另外，我们下载的RTD包，即使写明是K3，里面也会包含K1的RTD，这点需要注意。如果此时还没有装K1的development package，就会出错。 三．S32K1开发环境搭建 官网对于S32K3的软件划分为standard software和reference software，其中S32DS和基础依赖包在standard software中，可以很方便的找到。 但S32K1的官网却仅有一个reference software，页面也只能找到几个RTD（或SDK）链接：                                                  LiekLi_18-1655885108165.png                            图4 这里面所有的链接都不是我们需要的，全是RTD。问题就出在这里，K1的网页中没有K1的基础依赖包！而前面讲过，缺基础依赖包会导致RTD也无法安装。经过我研究，K1的基础依赖包隐藏的非常深，可以通过两个方法找到： 从S32K1的reference software进去，然后重新点击product list，如下图5所 LiekLi_15-1655884629434.png              图5         进入如下页面，如图6所示，这里最能看出来，针对K1的界面很不友好，需要点最底下的NXP Software. LiekLi_16-1655884629503.png              图6 在NXP.com官网首页搜索栏直接搜S32DS，找到S32 Design Studio for S32 Platform（注意不要选成for ARM或或者for PowerPC），从S32DS的主界面进入，然后一直下拉，找到S32DS service pack 1，这个才是K1的，如图7所示： LiekLi_17-1655884629606.png                 图7 这个链接更加隐蔽，要在40多个选项里挨个找。   经过上面两个方法，都可以进入图8所示的界面，然后再按图8所示操作： LiekLi_19-1655885288458.png              图8   这回终于到了最终可以下载S32K1基础依赖包的地方，如图9所示。我们需要重点关注一下命名，SW32开头的，会包含所有S32的development package，包括K1，K3，G；SW32K1开头的，仅有K1，同理如果你在K3的界面中，可以看到SW32K3开头的。 LiekLi_20-1655885302790.png            图9 下载最新版本的S32K1基础依赖包，然后再安装RTD，大功告成。

Hi,    Firstly, you should get the flash block size of your S32K3xx. Table in RM could be the reference. OliverTian_0-1641979572873.png    Secondly, you should know that there are super sector and sector in S32K3xx.   Sector                    Subdivision of the Flash Block that is independently erasable. Sector Size is always 8 KB. Super sector          Subdivision of the flash block that includes a group of sectors. Super Sector Size is always 64 KB, and consists of 8 sectors.    Thirdly, based on the information of PFCBLKx_SSPELOCK in RM, you can calculate the numbers of super sector and sector in each flash block.   OliverTian_2-1641979572947.png For example in S32K312, it has 2MB flash totally and each block is 1MB. So, in each 1MB, its first 768KB is with super sector granularity. The numbers of super sector is 768/64=12; the followed sector number is 256/8=32. Cheers! Oliver

Some customers inquire about the FreeMASTER JumpStart Project mentioned in the Get Started with the S32K1xxEVB. So here to talk about the problems you may encounter and how to solve them. FreeMASTER JumpStart project download.png Where to download FreeMASTER JumpStart Project Customers may not find where to download FreeMASTER JumpStart Project at the moment. It should be downloaded from the Embedded Software under Design Resources of the development board. But the download link of S32K142EVB \ S32K144EVB \ S32K146EVB is missing. Design Resources Embedded Software.pngWe can search the keywords “* JumpStart” at www.nxp.com download embedded application software and PC host application software that you need. Search JumpStart.png Which version of S32 Design Studio should be used The readme file will tell us which version of S32 Design Studio the project was created. For example: the readme in the S32K144_EVB_JumpStart_Firmware package shows that the project for S32K14x EVB JumpStart SW was created in S32 Design Studio for ARM v2.0. created in S32 Design Studio for ARM v2.0.png Which version of SDK should be used You may get the Validation of S32K144_EVB_JumpStart_Firmware Kinetis SDK project when import the project : The project S32K144_EVB_JumpStart_Firmware was created for Kinetis SDK SDK_S32K14x_08 which is not installed in this product (repository SDK_S32K14x_08 not found).  S32K144_EVB_JumpStart_Firmware SDK_S32K14x_08.pngThe chapter Version Tracking of S32SDK_for_S32K1xx_RTM_3.0.3_ReleaseNotes shows that the SDK_S32K14x_08 means EAR 0.8.5. Version Tracking S32SDK_for_S32K1xx_RTM_3.0.3_ReleaseNotes.pngBy default only S32 SDK EAR 0.8.4 is installed in S32DS for ARM 2.0, so we need to update the S32 Design Studio for Arm® v2.0 Update 2 – S32 SDK 0.8.5 EAR & MQX by refer S32 Design Studio for Arm v2.0 - Update 2 available S32DS_ARM_v2.0_UP2_K14x_SDK_085_MQX_170928.png Incorrect UART baud rate setting The baud rate selected for LPUART in Processor Expert is 600 by default, which does not match the description in the readme file. 600 is not in the FreeMASTER serial port baud rate support list, so let us reconfigure the baud rate to 115200 and then click Generate Processor Expert Code. select Baudrate 115200.png Generate Processor Expert Code.pngWhen connect S32K144EVB with FreeMASTER by UART, you can see that the Baud rate 300 is not in the support list. This is the reason why using the default configuration of S32K144_EVB_JumpStart_Firmware is not able to connect with FreeMASTER. Probing UART Ports.png      

Some customers inquire how to use FreeMASTER with S32K3. But there is no exists example projects which demonstrate usage of the FreeMASTER serial communication driver in S32K3 Real Time Drivers at the moment. So this article will introduce how to use FreeMaster SDKs in S32K3 RTD 0.9.0. Download S32DS \ S32K3 Development Package \ RTD (SDK) \ FreeMASTER Driver Login your account on NXP website, and download the S32K3 Standard software from TOOLS &SOFTWARE of S32K3 webpage. If you have already installed the S32DS3.4 \ S32K3 Development Package 3.4.0 \ RTD 0.9.0, then you can skip the following part and start directly from 4.Install FreeMASTER Driver 3.0 for S32K3 S32K3 Standard Software.png Download S32DS S32K3 Development Package RTD FreeMASTER Driver.png Install S32K3 Development Package 3.4.0 After install the S32 Design Studio v3.4, we should install S32K3 Development Package 3.4.0(SW32K3_S32DS_3.4.0_D2012.zip): go to menu "Help" -> "Install New Software" and click on "Add..." button Add Repository.png Here we uncheck S32 Design Studio S32K3 SDK (RTD S32K3 0.8.1), because we will install the newer version S32K3 RTD 0.9.0 later.

S32K3_EVB defined symbols.png Attach FreeMASTER_S32K3.png Select LPUART peripheral as host communication Through the description in the Requirements and Release Description chapter of FreeMASTER Driver Release Notes(FMSTRS32K3RN), we can see that currently only UART interface is supported. The S32K3 FreeMASTER 3.0 version 1.0.0 only support NXP GCC 6.3 or 9.2 for ARM at the moment, but the latest S32K3 Real Time Drivers Version 1.0.0 is based on NXP GCC 10.2.0. This is the reason why RTD 0.9.0 is selected in this article.  Requirements and Release Description FMSTRS32K3RN.png The README.txt also shows that: Current package provides FreeMASTER Communication Driver support for S32K344 over LPUART module README include_freemaster.png  LPUART13 is selected in this project for S32K3X4EVB-Q257, so we need to define the base address for FreeMASTER: #define FMSTR_LPUART_BASE           0x404A0000 define FMSTR_LPUART_BASE.pngModify the main function according to the README.txt: main.png Connect FreeMASTER3.1 to S32K3X4EVB-Q257 board Here we can see that the FreeMASTER3.1 is connected to S32K3X4EVB-Q257 board. connected.png

The purpose of this demo application is to show you the usage of the FlexCAN module configured to use Flexible Data Rate using the S32 SDK API. - In the first part, the application will setup the board clocks, pins and other system functions such as SBC if the board uses this module as a CAN transceiver. - Then it will configure the FlexCAN module features such as FD, Bitrate and Message buffers - The application will wait for frames to be received on the configured message buffer or for an event raised by pressing one of the two buttons which will trigger a frame send to the recipient. - Pressing SW3 button of board 1 shall trigger a CAN transfer that results in toggling the RED led on board 2. - Pressing SW2 button of board 1 shall trigger a CAN transfer that results in toggling the GREEN led on board 2. - This demo application requires two boards, one configured as master and the other one configured as slave (see MASTER/SLAVE defines in application code) or single board connected with CAN tool. - Both the event and error callbacks are installed, callback_test variable indicates event entering bit0 .. RX complete bit1 .. TX complete bit2 .. ERR INT flag set bit3 .. BOFF INT flag set - to enter bus off simply short CANH with GND and send message using either SW1 or SW2, FlexCAN enters bus off (error event) and blue LED is ON. Also TX MB is aborted.
