Automotive MCUs

Hello all, I'm new to ST Microcontrollers, and I'm currently facing a challenge in programming the board I'm using, which is the AEK-MCU-C1MLIT1. The primary issue is that I don't have access to a simple pinout diagram for this board, making it difficult to configure and utilize its various components effectively. While I know the mapping for LED_3, LED_4, and LED_5, I'm uncertain about the mappings for other essential components like GPIO headers, available ports, switches, and their configurations for input/output operations. Configuring pins in the pinMap Editor is quite challenging without a proper understanding of the pinout and port mappings. I urgently need assistance in obtaining a simple and comprehensive pinout diagram for the AEK-MCU-C1MLIT1 board. Having access to this pinout diagram would greatly aid me in configuring pins accurately, identifying available ports, and understanding the mappings for components like switches and GPIO headers. This information is crucial for m

Hello,On nxp website (https://www.nxp.com/webapp/etpu/), i saw than they have developed some function for the eTPU co-processor. But i don't know which "eTPU-equipped device " should i select to program the SPC56 and how to program it .Thank you

I want to use OTA for update, but there is no instruction. I don’t know how to update to sr6g7_evbc6000p_b through OTA.

Hi,It seems that the quadrature decode mode of the eMIOS doesn't exist in the eMIOS200.Is there a workaround for eMIOS200 to get the same functionality?Thanks.Markus

Hi community, I am working on L9788 IC with SPC57 K Line 144 pins. I can sent LVDS data, LVDS clock and Enable signal from SPC57 MCU to L9788 IC (downstream works). However L9788 IC does not sent me any response (upstream doesn't work). Moreover, when I check  mrd signal, I can not see any change on this signal. Is my L9788 IC working or not according to mrd signal? Can you help me with this subject? @Peter BENSCH @L9788  @SPC57

Hello,I am struggling with the individual RX CAN Message Filter RXIMRx on SPC570S.First Question:Is there an Application Note available for the SPC57x Note like it is for the for SPC58x (TN1348).Second Question:I want to use the RX CAN Message Filter RXIMR0 without FIFO.How is the extended bit IDE and the RTR handled in the filter oris it ok to handle extended and standard format only with the filter-range.If so how ist RTR activated deactivated. Kind regards in advance 

Hello,I am working on SPC57K-Line MCU with IC L9788. I want to use also GUI to configure and control L9788 through the MSC bus. But I always see this error "Failed to reset MONACO". I tested COM port and UART connection and all connections are correct and working. In website, I saw the L9788 can be connected to the SPC563M-DISP directly and GUI can be used. Can I use this GUI with SPC57K-line board? If yes, could you please provide elf file? Because the elf file given with GUI folder is for SPC563M-DISP board. (like STSW-L9788.elf)Btw, if there are any preconditions to receive message from l9788, please inform me.Thank you                   

I need one part no of MCU which will meet automotive standard and have MCU 32-bit ARM Cortex M0+ RISC 512KB Flash 2.5V/3.3V 32-Pin, 512 KB flash Memory, 64 MHz clock rate and operating temperature is -40 to 125 °C.

Hi, I've made a custom board using an SPC5 microcontroller for my automotive-based application, but I've been facing the issue that I need to flash my code with my external SPC5 debugger every time I power up my board, and then only it starts working. I'm not sure whether it gets erased every time I turn off the board or whether the code gets struck when I power up my board. and I don't face this issue on my SPC5 Discovery evaluation board.

Hi,I was trying to program a SPC58EC-DISP board with a TCP code and after a while it turned on the red reset LED. After that, all my attempts to reprogram the board were impossible.I tried it with and without the jumpers of the JP5 connector, the configuration of the board with respect to the rest of the jumpers is the factory one. I even tried to keep the reset button pressed while trying to reconnect the board and modify the JP33 to try to get the connection with the PLS but I couldn't.I have 2 other SPC58EC-DISP cards with the same jumper configuration and I can connect with them without any problem, so I guess it's not software problem.Can you help me get the board working again?

I want to flash and debug using SPC5-UDESTK 5.02.04 on to the board SPC5746CBMKU6. This controller configuration is not given in the tool. So I have created new configuration for this board. Now I have tried to connect to target board. But it is failing to establish connection. Connection and power supply is good(Tool LED glows). May be problem with target configuration. Attaching failed report and new target configuration file(in .txt, as .cfg is not supported here). Kindly provide the target configuration file for SPC5746CBMKU6, if you have. Or suggest edits in current file.  

Hi I need to flash via CAN bus and I understood it is possible using SPC5-FLASHER on PC connected to the target via USB/CAN interface with SPC5_UPDATER_CONN=SPC5_UPDATER_CONN_CAN. But I need also to flash a target from another target with SP57xx so I would like to have the source code of SPC5-FLASHER crosscompiled for my target .. Is that possible?ThanksFabio

Hi guys, I'm using RM0421 as reference for my develop work.But find some error in Chapter 5.1 Table 6.The end address of 256KB Code Flash block 4 and block 5 should be 0x0113FFFF and 0x0117FFFF.Is that correct? Kind regard! 

Hi all,I am using SPC582B mcu.The system timer is based on PIT0 CH0 (default choice) at frequency 1kHz.In the timer IRQ handler, I need to invoke SPI spi_lld_exchange API. Problem is this API doesn't complete, remaining stuck on the whileSPC5_SPI_WAIT_FOR_TXRX_COMPLETION(spip);   SPI APIs are configured synchronous: I already activated the preemptable ISR option in the configuration: Since I don't know if the priority level is ascending or not, I tried both priority situations, that is: System timer (PIT0 CH0) priority: 4                    DSPI0 priority: 10System timer (PIT0 CH0) priority: 10                  DSPI0 priority:4  Is these some configuration flag or API to call in order to make this SPI API working? Thank you all for any help or indication,FP

Hi, I have been working with the board for quite some time and everything was functioning normally. Last day, upon powering the board, I noticed that the board has entered reset mode. Also, I have been unable to establish a JTAG connection.Do you know the possible reasons behind this unexpected behavior, specifically the board entering reset mode? Are there some ways to restore boards functionality?Attached please find a picture of the board in its current state.

Hello community,An automotive client that i'm working with wants to devolope his own bootloader basing on ST bootloader on SPC5 product. my mission is to validate this bootloader on SPC5 eval bord of ST.So , im asking if there is a specific HW and SW tools to validate CAN UDS bootloder. Also any documentation about CAN bootloader could helpThinks in advance Farmer ST engineerZied ben Amira

How does one go about setting main() to address 8?Or any address, but I thought I'd be specific so I can see what the mechansim is to set things to specific addresses.  If you have a map input file (I see the out.map).Also, getting error: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/bin/real-ld.exe: build/out.elf section `.bss' will not fit in region `ram'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/bin/real-ld.exe: region `ram' overflowed by 3792 bytesNo idea where to look for the problem or how to correct.  Not new to embedded software and this is usually in some sort of linker file etc..usually can fix these things by a descriptive output file that fully describes the location and sizes of the code...but where...hmmm w
