Automotive MCUs

Anyone here do ECU project with GTM on SPC57?what task/function should I add on loss lock callback of the GTM DPLL? I saw some samples project, they switch to half cycle ( 360 degree ) on the loss lock callback event. but I still have no clue the benefit of this such task. perhaps anyone here have some suggestions.

Where could I find a reference schematic design for SPC582B50E1 IC?

I need help understanding the SARADC test application code. Can anyone explain to me how the code works?

what is the worst case current consumption of SPC584Cx ?

How can I get the document of SPC582Bx IO_ Definition document?

I have shortlisted the following microcontroller https://www.st.com/en/automotive-microcontrollers/sr6p7c8.html#tools-software for one of the protoype demonstration. For this prototype development, I will be using MATLAB Simulink, to create a model and then inturn create a c/c++ code using Embedded Coder Block. Since MATLAB does not support directly this hardware (It supports code generation for ARM Cortex R controllers). I would like to know where can I find board support packages or SDK for this microcontroller? 

I loved the approach that STM32 had a IDE for MacOS. It looks like there is none for SPC5. Is that correct? I would love to start developing with SPC5 and my newly bought evaluation board, but the download page only features a .exe file.. 

Im using the subjective model where can i get the project examples

we are working on a new devlopment project.we need reference design with "GPS + GSM + WiFi + RFID + Bluetooth + CCTV" all these requirement.please suggest the reference design full-fill above requirement.

Hi Team,I am working on SPC58NE84.Does SPC58NE84 supports CAN overload error? Best regards,Abhishek

Hello,I know this is a bit of an edge case but during some testing today I noticed that the low level CAN drivers that come packaged with SPC5 studio only use the DLC field to work out how many bytes are in a recieved CAN the message. This isn't strictly correct as ISO 11898-1:2003 permits a standard CAN frame to have a DLC of > 8 which should be interpreted as a message containing the maximum 8 bytes. Unfortunately this ended up causing a hard-fault for me as the driver was trying to work on 64 bytes when only 8 had arrived. I have patched this locally by also checking the EDL bit when working out the frame size and thought this is something you may want to include in future.Many thanks,Owen 

I'm trying to install a license and change my computer.Please tell me how to reset license.Indicates that it is being used by another PC.

Dear valued customer,Your registration has been received.However these activation key------------------ and serial number ------------------ have already been used on another node by another users in another company.Since SPC5UDESTK are single-user node-locked licenses you will need a new activation key and serial number of the SPC5 USBJTAG adaptor.Please ask your distributor of the activation key to solve this issue. How to initialize a license? You can buy full licenses of SPC5/UDESTK directly from STM

Hi,I have troubles with the new version of SPC5Studio.I have made a bootloader with SPC5Studio V. 5.8.1 which is working fine but when I have remade it with the new SPC5Studio software it doesn't jump to application code. This is what happens: The bootloader starts correctly when I send the id upgrade message from CAN. It saves correctly the application code in Flash memory. After that, I turn off the device and then ,after few seconds, I turn on it. After few checks it jumps to the application code but here is when I saw two different behaviours : bootloader's code with SPC5Studio version 5.8.1 can jump to application code, the one with SPC5Studio version 6.0.0 fails. They have the same source code, same memory map and the only few changes are that which are generated with "Generate SPC5 Application" button. Any suggests? Could I receive SPC5Studio v. 5.8.1 version in order to compare the auto-generated code? Thanks in advance.

I use spc58nh-disp develop board.I want to enter the standbymode. but can't enter.If i setup SPCSetRunMode(SPC5_RUNMODE_STANDBY0) in main loop, It's behave.But after i get the RTOS, core0, core1 and core2 working, If i work SPCSetRunMode(SPC5_RUNMODE_STANDBY0), is not working.what is problem?ex)--> standby mode working codeint main(void) { componentsInit();wkpu_lld_start(&WKPUD1, &wkpu_config_wkup_cfg);if (SPCSetRunMode(SPC5_RUNMODE_STANDBY0) == CLOCK_FAILED) {SPC5_CLOCK_FAILURE_HOOK();}runCore0();runCore1();vTaskStartScheduler();   for ( ; ; ) {  }} --> standby mode not working codeint main(void) { componentsInit();runCore0();

I read from the OpenOCD docs in spc5 studio, I can only found sample instructions OpenOCD for spc58 family. But can't find any info about spc57 family support. Did spc5 studio openocd also working for other spc5 mcu family? 

I use SPC58nh-disp.I use "time.h" and clock() function.but occur errorlike" c:/spc5studio-6.0/eclipse/plugins/com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514/toolchain/bin/../lib/gcc/powerpc-eabivle/4.9.4/../../../../powerpc-eabivle/lib/e200z4\libc.a(lib_a-timesr.o): In function `_times_r':timesr.c:(.text._times_r+0x2): undefined reference to `times'  "how to solve??  or Are there other ways to measure execution time???? 

I am a bit too new to this St universe, could someone please point ,me in the right direction?I would like to update the Firmware on my BMS L9963 board. I found a folder on the website for the GUI for download. It contains a ELF file and some .dllsHow do I transfer this onto the board? I have SPC5 Studio and the Autodevkit installed. There are no samples for that BMS other than an example for timers (?).How? Why? :) Comming from the Arduino universe I am very very lost right now. Maybe someone could help? Is there a noob guide somewhere? How to get all of this going? 

I tried to periodically send SPI data using PIT timer on SPC572.but whenever the timer interrupt call the SPI to transmit the data, the MCU freezing. while, when call the SPI transmit from main function, it working fine.any suggestion to solve this issue? thanks 

Hi all,I'm working on SPI communication between SPC582B and peripherals. I succesfully made it but I've found,  delay between characters sent by CPU is about 8us in 1MBit mode. Delay between last transmitted bit and tfff (transmit FIFO not full) is about 5us. How (and if) can this delay be reduced?regards

Hi,i used SPC5Studio 5.8.1 for many years, but today (after windows update) in Properties->Tool Chain Editor->Current toolchain->"No ToolChain".This means that i have no possibility to change Build Settings. The same things also in SPC5Studio 6.Of course i have C:\SPC5Studio-6.0\eclipse\plugins\com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514\toolchainSomebody can help to fix this?Thank you in advantages.

Hi. I am currently working on a project that involves implementing a data reception feature using the SPC584B-DISP board and the example application "RLA Serial DMA Test Application for Discovery 2."The objective is to efficiently receive approximately 3kbytes of irregularly sized data. After evaluating the Half and END Interrupt (Rx Callback) method, we found it to be inefficient for our requirements. Instead, we are interested in using the idle interrupt to achieve better performance.To proceed with the implementation, I would appreciate your assistance in understanding the necessary registers and methods to achieve our goal.Thank you for your time and support. We look forward to your kind assistance.

Hi1) Is there specific document available for Flash (NVM) Access and Operation.2) What is the default value of NVM @ Power On?3) Error handling while programming the NVMThan you

Hi guys,In my project, i am implementing DMA-SPI Tx/Rx for SPC58NH.Interrupt SPI is verified. Communication is checked.Problem is when i activate DMA for specific SPI channel, it triggers DBE(destination Bus Error).For example, DMA ch 12(DMACHMUX_0) - DSPI 3 Tx, it always reports DBE flag and there is no Tx(monitored by Oscilloscope) and of course, there is no data in PUSHR(Tx data)But DMA ch 12 - DSPI 0, 2, 4, 6 are working without DBE flag, i also can monitor data in PUSHR(Tx data).Funny thing is DSPI 1, 3, 5 are not working with same flag.I believe SPI/DMA configuration has no issue, if it has issue, it shouldn’t work with other channel.I’ve tried to search related information but it has very less information about DBE. If you have any clue on this, please share your knowledge.Thank you!  

Actually I want to use Discovery Kit for SPC56 B line with SPC560B54L5 MCU in my project and I need SPC5Studio Software tool for configuration and all. So please provide me some information like Software License is free or need to purchase?? If need to purchase then cost or procedure??
