Automotive MCUs

Hi,I am currently working on the SPC574k Discovery board and having issues with getting an Output on most off the pins. In my attached image configuration I only get an Output on ATOM1_0, ATOM1_1, ATOM2_1 and ATOM3_0. I use the MCS Module to generate an output for each channel. I checked the code for the mcs module and if I route the signal from originally ATOM1_4 to the ATOM1_0, the correct signal apears on the ATOM1_0 Pin.I am also not able to control a number of Pins via the normal GPIO function even when they are correctly configured.My question, is there some additional limitation in the GPIO Matrix of the chip? Do I have to set a configuration in code to get certain pins to work or could I have a defective Microcontroller?Kind Regards,Sir_Alee

Hello,(@Gidi)Does a FreeRTOS BSP for SR5E1-EVBE5000P exist?Yacob. 

Hello Community,I have just started working with the Stellar SR6P3 microcontroller.Do you have any CAN XL application examples or CAN XL driver examples available?I have searched within the Stellar SDK, but I could only find examples related to CAN / MCAN, not CAN XL.Could you please help me with this?For your information, we have already signed the NDA.Thank you very much in advance.Best regards,

For everyone who is thinking about starting a project on an SPC5x MCU: don’t. Just don’t. On paper, it looks great. Beautiful marketing slides. Pin mapping, clock tree, HW initialization… a cheap multicore debugger… everything you could ever want. Amazing.  You want to set the clock? Cute. Unfortunately, for your E-family MCU, there is no clock tree. Because… reasons. Oh, you want to set up GTM? No problem! There’s a default configuration, just pick what you need. Just don’t pick ATOM3. Or ATOM4. Or anything beyond ATOM2, really. It won’t work. No warning, no error, no hint. It just silently does nothing. What about ST support? Haha. Good one. You already designed your PCB using ATOM3? Congratulations. You can now spend a few months trying to make it work before finally hot-wiring your board like it’s a Soviet-era radio, just to avoid ATOM3. Along the way, enjoy the complete lack of driver documentation. Good job! After enough pain, your basic application is now somehow running. T

Hello, recently, in attempt to create custom software for SPC56EL70 programming, I have encountered a problem to successfully launch RAM located program inside of the MCU. Discovery board is used for the test.Programming operations are commit via JTAG, and communication layer is already built and shows no faults. Full read of flash memory of the processor was successfully done. Since I haven't worked with any of SPC MCUs before, my JTAG set of instructions are based on MPC5xxx line, so you can assume that main issues might be in key differences between these methods.Firstly, in SPC5 Studio IDE, program for test is created, for example "led blink". For program .ld file is corrected for all segments to be located in RAM(No entry adjustments, ORIGIN is adjusted to ram).MCU is started, MMU, SRAM, are initialized. Bin file is then loaded to RAM(it is then checked for presence), and after that CPUSCR instruction is passed with PC having 0x40000000 - 0x04(NOP as IR) address where program

Hi Team,We are not able to generate the Centre Aligned PWM for the SPC58NN board which has GTM Module.We are using ATOM Channel 1, where we have set the mode to SOMP and Umode as Up and Down till CN0 reaches 0.Can anyone give us the baremetal code which generates the centre aligned PWM.Thanks in advance.

Hi, I am trying to debug a program running on a SPC56EL MCU, but can not find the device on the list in the debug configuration tabhow can I add SPC devices to the list?

Hello, does the SPC58EG80E5xxCxx variant have the checker core feature for core 0 or is the checker core unique to the ASIL-D variant such as SPC58EG80E5xxHxx? 

With the MCU enable BAF and Core0 / 1 /2 reset vectors are place at 0xFC0008 / 0xFC0004 / 0xFC000C, my question is how the 3 reset vector be called during power on? just be called one by one? the reference manual doesn't give clearly description; this confused me a long time.

Hi everyone,I’m working on configuring the SARADC in the SPC58ECxx using the RLA (Low-Level Drivers) tool. I want to read an analog signal on PE0 / ADC-AN11.In the SARADC settings, I see the following options:SARADC BSARADC 0SARADC 1SARADC 3SARADC 10bit modulesSARADC STANDBYI’m a bit confused about which options I actually need to select. I understand that SARADC0 is the module connected to my pin, but I’m not entirely clear on the purpose of SARADC B and the other options.Could someone clarify:What each of these options actually does.Which options I need to select if I only want to read PE0 / AN11 with SARADC0. 

Dear Team, We are currently working with the SPC582B60E1MH00Y MCU in our project development. In our application, the ESP32 reads the firmware file from the cloud and sends it to the MCU via UART. As part of our application, we need to implement a Bootloader using UART communication. However, we do not have prior experience with the Bootloader implementation on the SPC58 series MCU. The hardware design has already been completed, and the SPC58 UART is connected to the ESP32 through the LINFlex1 serial interface pins. Kindly confirm whether these UART pins can be used for the Bootloader application. We kindly request your support in developing the Bootloader application for our project. Additionally, if you could share any reference documents or sample projects (UART Bootloader code), it would greatly help us to progress further and improve our development status. Our queries:How does the Bootloader work, and how can it be handled in the SPC582B MCU?Could you please share

Hello,I am facing a connection issue with SPC5 Flash Programmer version 2.8.1 when using UART communication with SPC560B64.Setup:Target MCU: SPC560B64External crystal: 8 MHzInterface: UCUART::HybridCom/7/UARTSame hardware setup as previously used successfullySPC5 Flash Programmer v2.7.9 works correctly on an older PC, v2.8.1 (and newer) fails to connect.The software stays in “Connection phase starting” and continuously retries, the UART interface LED does not blink. No connection is established.Same SPC560B64 device, same UART interface and wiringAre there any required driver updates, configuration changes, or compatibility notes for newer versions?

In the datasheet it is given at 40MHz the max C_L is 8pF (from AN6027), but the C_L in the design schema has C1 and C2 8pF(UM3305), which gives 4pF, could you suggest me with the external crystal oscillator design. And the range is from 4MHz to 40MHz,  so if for a chosen crystal , should the minimum frequency satisfy this condition ?  

Dear ，       Would you teach me how to set SPC582B DSPI 40bit data frame? I use the SPC5Studio-6.0.0-Doyle, you can see my attached picture.The biggest setting of SPI frame is 32 bits.  but the data sheet says "programmable serial frame size of 4 to 64 bits, expandable by software control"Would you teach me how to set SPI frame 40bit?  

I am using stellar studio 8.0.0.in Debug perspective, I can only find the Expression view, but cannot find the Live Expression view in "Window--show view". With Expression view, the monitored variable will be refreshed only when pause the debug session,if it has Live Expression view, I can watch the variable value without need to pause.So I want to know if stellar studio have made the Live Expression function or similar functions now?

I am trying to connect to the SPC574K-DISP board through PLS UDE Starter kit to program but am getting a "Can't determine the default communication device! Current selection is ambiguous!" Pop up error message.I followed the Part 7 - AutoDevKit™ detailed tutorial: Debug and release of firmware created with AutoDevKit™ tutorial step-by-step (though I'm using a different board, and I used the RLA IRQ Test Application). To get to this step.I am using a new SPC574K-DISP board for this, it has not been used/programmed since it came out of the box this week, so I can't verify that it's not a board issue. Though, when powered, the board runs it's Blink LED test application.Device Manager shows two instances of "SPC574K-DISP Discovery+" under "Other devices", before I install the PlsUsbJtagDrivers, and still the same after, see attached "SPC574K-DISP Investigation_Device Manager.png". If I install the UDESTK drivers from SPC5Studio's OpenOCD, then the Device changes to a COM Port cal

I have the SPC5Studio software installed. Installed everything I could find in the Help-> Install New Software. Found two help files in openocd-> docs section in the SPCStudio folder on the C drive. Only one applied, so as far as I know these are the latest drivers. UDE STK 5.2 and UDE STK 221 are both sitting on the desktop and do not do anything.Nothing I have tried has worked, any insight would be deeply appreciated.ThanksMike

Dears, How can I get SENT SW demo code described in TN1233? Thanks.

 I can use stellar studio to flash the new software when start a debug session, but I want a separate tool to just flash the new software just like Stm32CubeProgrammer.Does Stellar team have made such tools?

Hello,I’m experimenting with a simple RAM loader for SPC58 loaded through BAF over CAN.The same program runs perfectly when I debug it in RAM using UDESTK, and I’ve adjusted the linker so the code starts at 0x40070000. It initializes CAN, does a few GPIO tests, etc. — all good under the debugger.However, when I upload the same image to RAM via BAF, it starts but crashes as soon as it tries to initialize the clock, and if I skip that, it later crashes on peripheral initialization (CAN, GPIO, etc.).So my question:What are the main things I’m missing for a program executed directly from BAF in RAM?Is there something specific about system/clock or peripheral state that must be skipped or re-initialized when booting this way?Any hints or example references for a working SPC5 RAM loader via BAF would be very helpful.Thanks!— Janis

Hello, Is there any application like Power Consumption Calculator (PCC, which is embedded inside the STM32CubeIDE) for SPC5 microcontroller Family?I am using SPC58xCx and SPC58xBx lines and need the current consumption data for microcontroller core, peripherals, and I/Os.Best regards.

Dear ST Support Team,We are currently developing an IoT-based mining vehicle monitoring system, which generates a large volume of operational data that must be stored and accessed locally. Due to this high data size, we are evaluating the use of SD card or eMMC memory, with a stronger inclination toward eMMC as our final storage solution.For structured and reliable file handling, we are planning to use the FATFS file system for read/write operations.We would like to confirm whether the SPC58NH92E7 microcontroller officially supports integration with FATFS on SDMMC/eMMC interfaces. If available, kindly provide documentation, application notes, or official reference examples demonstrating FATFS usage with this MCU. Tool we are using to flash controller:SPC5 StudioAuto devkit Thank you for your support.
