Automotive MCUs

Could someone clarify the interrupt priority order for SPC58 MCU family? Is 0 the highest priority or 63 is the highest priority?Best regards

I’m working on an SPC560B MCU project that includes both a bootloader and an application. The application runs without any issues. However, when running in bootloader mode, the MCU experiences repeated resets.Upon checking the RGM_FES (Reset Generation Module – Fault Event Status) register, I can see that both F_CHKSTOP and F_SOFT flags are set.I’m trying to determine what could be causing this reset behavior. Some specific questions:What are the typical causes of F_CHKSTOP and F_SOFT resets?Are there specific registers or debugging steps I should look into to pinpoint the root cause?Thanks in advance!

Hi,   I'm learning to use it SPC58EC serial chip and have a question,when it was previously used on Arm chips, there were some exception handling interrupt functions,like Hard_Fault_Handle,this ensures easy traceability when problems arise, my question is how to configure similar exception interrupt functions on this chip（SPC58EC），I would appreciate it if you could provide some examples，thank you very much

Hi there,I am working with a company developing an automotive control module that connects to several systems that must be able to wake up the module from STOP mode or Standby modeOne of the modules signals the wakeup request over the CAN bus, and I was wondering if it was possible to integrate this functionality into the firmware of the SPC582B60 microcontroller.I had a read through both the WKPU and MCAN sections of the datasheet, and could not find any conclusive information about how I might go about this or whether this functionality is supported in this microcontroller.Any suggestions for implementation of this functionality, or alternative microcontrollers that may provide this functionality will be greatly appreciated.Kind regards, Rusira

Hi I am using UDE STK 2021 debugger software and for that I am using PLS-UDESTK debugger(HW), for SPC58NN84E7 microcontroller  I could see the PLS-UDESTK is mentioned as NRND(Not recommended for new design) So I am planning to use AEK-MCU-SPC5LNKU with same above mentioned SW debugger. Can you any confirm me that AEK-MCU-SPC5LNK supports UDE STK 2021 SW debugger Thanks in Advance   

Hello,I am currently exploring the SPC5Studio IDE for developing applications on SPC5 family microcontrollers and have a couple of questions regarding its features:1) Licensing Requirement:Does SPC5Studio IDE require a licensed version for full functionality, or is there a free version available for all users?If there is a free version, are there any restrictions or limitations in its features compared to the licensed version?2) Programming the MCU Using a Debugger:How can I program the SPC5 family microcontroller using a debugger in SPC5Studio?What are the supported debuggers and programming interfaces (e.g., JTAG, SWD) for this IDE?Is there a step-by-step guide available to configure and use the debugger for programming and debugging SPC5 MCUs in SPC5Studio?3) HAL Layer Support:Does SPC5Studio provide support for the Hardware Abstraction Layer (HAL) for SPC5 family microcontrollers?I would appreciate any insights or official documentation regarding these topics.Thank you in advance f

Hello everyone,  I am currently working on SPC5 microcontrollers and a bit new with SPC5 studio can anyone guide me how to make an application for running SPI , I am clear with the basic of SPI communication.      

Hello All,I am doing project that Controls Watchdog Adc to trigger interrupt for higher Threshold value and lower Threshold, When Threshold Reaches Maximum and Minimum ISR happens, in ISR function it blink onboard led.Using Onboard POT for watchdog adc Tuning High Threshold and Low thresholdOnboard LED Blink for ISR -Threshold high and low Interrupt For this I am using SPC560d Dev board . We have Example Application Library for ADC it has all the function to work properly, but i want to do on my own by Register based using Xpc560d.h header fine, for that i cleared main.c file in Example ADC Application Library. Now I struct at Clock configuration for Watchdog Adc, Below code when debugging, program hangs on Clock configuration like api configI have selected Sysclk-->FIRC  in RLA clock treeSysclk= 48mhzRun mode : DRUN RUN0 mode pheripheral clock 24mhz  PINOUT:PB[10]=ADC_1 Extended channel 6PC[2]=GPIO output LED PC[3]= GPIO output LED &nbsp

I would like to know, in the Stellar SR6G7, whether the BCS code will execute first or if we can configure a custom Boot Manager to execute first. Since I need to run secure boot with HSM, I want to configure the Boot Manager for PLL clock initialization and run the HSM first. Then, the BCS will execute the handshake with the HSM. Is this possible in the SR6G7, or will the BCS handle initialization and perform the handshake with the HSM during startup before any custom Boot manager?

I have SPC58NH-DISP board for my application development. I am trying to program the board using SPC5Studion but I am unable to do it. For me "Execute and Debug Your application" task is disable even if in SPC5Studio UDE plugin is installed. UDE plug in is installed by using this link : "SPC5tools - http://spc5tools.spc5studio.com"". NOTE: Board is connected and power supplied.

HiI am using SPC584B70 and LIN transceiver(TJA1021T) for LIN communication and I have a question.TJA1021TI need to create a break signal first for LINcommunication but I don't know how to create this signal in the current library.The current structure is to pass serial data to the TJA1021T chip, and the chip converts it to a LIN signal and sends it to me.The library I am currently using is serial_lld.c and I have checked that Tx and Rx work fine using this library. The signal on the left is the signal generated, and the signal on the right is the signal you want to make. This photo proves that Tx is doing well.* Is there any way to generate and send a break signal using this library?Or is there any code where I can see an example of lean communication? I know there is a lean communication library (lin_lld.c). It would be nice to see an example of this library.Thank you very much.

HiI try to program SPC564B74L7 target with using BAM function by serial port (SCI). I use an FTDI USB to RS232 adapter (USB-RS232-WE-1800-BT-0.0). Despite several attempts, I can't connect to the target from SPC5FlashProgrammer (version 2.8.1 Beta). In the Interface drop-down menu, I have selected my UCUART::FTDI/0/UART cable (which is the only suggestion). I have no activity on the serial bus when I click on Connect. Has anyone encountered the same problem as me and would they have a solution?

I am getting the errors below when trying to build the project.Due to reasons, we regenerate the project and now this project cannot be build ...I have tried the solution at Solution 1 and Solution 2. I have check that i have the full access to the workspace folders and the error illustrated below are copy and pasted from SPC5 6.0. (I prefer using 5.8.1 because it seems that opening up the project in 6.0 does import the correct low level driver setting correctly.)(We don't backup the component folders because it appears it need to be regenerated each time it is imported on a new PC) make -j6 allCompiling boot.sCompiling crt0.sCompiling vectors.sCompiling ivor.sAssembler messages:Fatal error: can't create build/obj/crt0.o: No such file or directoryAssembler messages:Fatal error: can't create build/obj/boot.o: No such file or directoryCompiling spc5_lld.cAssembler messages:Fatal error: can't create build/obj/vectors.o: No such file or directorymake: *** [components/spc560p

I've been using for a bit a SPC58 eval-board and i was wondering how to share global variables between the two cores. I searched around on the internet finding nothing useful. Is "volatile int" enough even for a rough and dirty data sharing or should I use something like SRAM and its shared memory location?

When replacing L917A how should I reboot it, what hardware or software do, I need please help.*This post has been translated from Persan to comply with the ST Community guidelines.

Is it because some jumpers on the SPC574K exploration kit board need to be connected, or is it for other reasons that the UDE STK software cannot read the chip through the emulator of the SPC574K exploration kit board? 

While debugging the board AEK-AUD-C1D9031 , the SPC5-UDESTK is not responding and it says this always even when the target power supply is turned ON and the Device is shown in Device manager. I think there will be some target configuration which I have to do but I am not aware of the Configurations. I have attached the message for reference. Kindly reply back as soon as possible.Message from component 'PpcJtagTargIntf' : Can't connect target !Message from component 'PpcJtagTargIntf' : No JTAG client found !Please check: - target power supply - JTAG cable connection - target configuration  

HiOn power up the SPC56EL54L5CBFS looks like it is in an internal RESET mode that does not  end. The RESET pin is always  pulled down by the CPU. Power up of 1.2v and 3.3v in 1.5msec. Can you help to to understand why the RESET pin is always  pulled down by the CPU? Thank you.

Hi,Can anyone help me?Thanks 

I’m engineer from EMS company. For one of our customer we are going to manufacturing PCBA (Vehicle Control Module) based on SPC58NH92C5 uC. Our customer is owner of design and our customer develop the final firmware for product. However for the manufacturing process we will need kind of the special firmware called “Test Firmware” optimized and dedicated to allow to perform Final Functional Tests of the PCBA. To optimize production process there is the plan to follow in that way: perform programming withfinal firmware > depanel and coating process > Full Functional Test (in here I need test firmware functionality).As you see I can’t reflash PCBA on Full Functional Test due to that PCBA already is flashed with final firmware. In that case my plan is do not touch Final Firmware but I would like to develop my own test firmware and I would like to upload That firmware do SRAM instead of Flash memory and boot uC from SRAM.I see that SRAM for that uC is 1MB so it is more than I nee

I would like to know some information about OTP programming in production for the Stellar SR6G7. What are the pins required to set the high voltage? I couldn't find clear information about VDD_OTP in the reference manual. According to the reference, I can see an NVMTMI eFuse with VDDINT and VDD_HV_NVM_PRG. But i think these are no the pins. Where can I find OTP Programming information? Is there any production documentation available?

helloI have just started working with SPC5 studio and I want to use PEMicro for debugging, but no matter how much I searched, I couldn't find anything that could help me in this way. My main problem is that I can't I set the software to PEMicro to debug with this programmer, and I read all the questions in this field that were asked on the site, but it did not help me. If there is a tutorial in this field, I would be happy if you could help, thank you.
