Dear ST,As you can see from the title we have issues with our SPI connection to the BMS board. We wired everything properly to the BMS connector, checked all the connections, on the MCU-C4mini shorted the JP pins (JP1 and JP2 and JP3 1-2, JP4,JP5,JP12,JP13).We also flashed the pre-built project from AutoDevkit studio (AEK-MCU-C4MINI - AEK_POW_BMSCCTX_GUI_application for discovery) to the MCU.Followed all the steps.We didn't connect any thermistors, and we only have 4, 3.2V LiFePo4 batteries.On the BMS, only the LEDS D2, D8(Blue) and D9 were lit up ~~ we assume the SPI connection is not being established correctly. We hooked up the SPI lines to a osciloscope, please find attached our readings. If needed I can also send a additional osciloscope reading picture.The yellow line is supposed to be the CLK line, we measured from the tiny peak to peak freq of 5MHz, the freq of the whole clock frame was 10kHz.Please advise how to continue with troubleshooting.  Best regards,Gabri

Hello AutoDevKit Support Team,I’m setting up an AEK-MCU-C4MINI1 board and I’m unable to get a working debug session through the board’s mini-USB (P2). I’ve read the user manual, followed the bring-up steps, and tried several configurations, but OpenOCD never manages to see the device over JTAG.SummaryExpected: OpenOCD starts, identifies the SPC58 device, and GDB halts at main().Actual: OpenOCD starts but repeatedly reports JTAG scan/IDCODE errors (“all ones”; IR capture 0x3F). GDB then disconnects.HardwareBoard: AEK-MCU-C4MINI1 (power to J2 = 12 V, S1 ON; D10 LED on)Connection: single mini-USB to P2 (no external probe connected to J3)Windows Device Manager shows:Ports (COM & LPT): AEK-MCU-C4MINI1 (Interface 1) (COMx)USB devices: AEK-MCU-C4MINI1 (Interface 0)USB IDs seen via Zadig: 0483:049A for both interfacesHost / ToolsWindows 11 x64AutoDevKit Studio 2.6.1OpenOCD bundled with AutoDevKit: 0.12.0+dev-00318-g0e98d766eGDB: ppc-freevle-eabi-gdb.exe (AutoDevKit toolchain)ProjectNew SPC

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.

Dear Team, @Max VIZZINI Sir, Help us to Solve this issue.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

Hi Team,I am trying to communicate with my bms using raspberry pi.I am using 8 cells in series connected to AEK-POW-BMSCCTX from C0 to C8 (from cell taps-P1 connecter). From the P4 side VIO-3V, Vdd- 5v, GND. I have also connected the MISO,MOSI,CS and CLK of the pi with corresponding pins in bms. Also TXEN-high, DIS-low, BNE-low.Using this run a sample Spi code and there is no correct reply. I just need to know is this connections correct? any extra connections do i have to do?Also after connections, D9,D8 and D2 leds of my bms is light up. When spi is activated D7 led should blink but not in my setup. I hope i get this problem solved.Hardware we’re using now1× AEK-POW-BMSCCTX (one node powered with 8 cells for bring-up).Raspberry Pi with /dev/spidev0.0 enabled.Cell stack: C0..C8 populated (8 cells ≈ 26 V).Two GND_EXT pins tied to pack negative as per BMS hold manual.Actual wiring (current)P1 (cells)C0–C8 → 8 cell taps (≈ 26 V total)GND_EXT(×2) → pack negativeP4 (logic, to Raspberry Pi)

Hi Everyone, I´m trying to find the BSDL File for SPC56EC74B3C9EEX. Someone can share me the file.? Sincerely, Ruben Gonzalez

I'm looking for ST's GNSS components that I can build a GNSS receiver which can give offline high accuracy. To do this I need to do extra DSP between front end and baseband processor. What RF front ends are actively being produced that gives down-converted IF analog or digital outputs? 

Hi. I'm looking for a programmer for SPC564L60L5. The best would seem SPC5-UDESTK but it is not available for sale. Or maybe StellarLINK It will be ok for full programming and debugging support for this chip. Or maybe some other suggestions of a programmer who would support SPC564L60L5?  Thank you for your help Best regards Christopher   

Hi everyone,I am having trouble with the Teoseo VIC3DA GNSS module:My project is using the Teoseo VIC3DA to obtain information about GPS, gyroscope, and accelerometer, but in the default mode, I cannot see any data from the gyroscope or accelerometer. Therefore, I have tried sending the following commands:Tried to read Gyro data$PSTMDRSENMSG,31*<checksum>$PSTMDRSENMSG,30*<checksum>I even tried enabling/disabling the PSTMDRGPS message according to table CDB-ID 228 - NMEA message List 0 with the following commands:$PSTMSETPAR,1228,800000,1 (enable message PSTMDRGPS in current config)$PSTMSETPAR,1228,800000,2 (disable message PSTMDRGPS in current config)=> The Teoseo VIC3DA still does not change (I have also tried enabling/disabling other messages according to table CDB-ID 228).Only the $PSTMGETSWVER command receives a corresponding response.Additionally, I would like to provide you with the log from the GNSS module starting from the moment the Reset was triggered at attach

Are there any C++ Dual Core demos/examples/instructions for using the SPC58EG (or any SPC58 examples) for configuring, initializing and executing?

Hi everyone,I’m working on a project using the SPC58NH92 MCU with SPC5 LLD (RLA) drivers.The setup runs FreeRTOS on Core2 and bare-metal code on Core0.Both cores share data through a dedicated RAM region, with synchronization handled by SEMA4 for access control and cache invalidate/flush operations to maintain data coherence.The application works perfectly when compiled without optimization (-O0). However, when I build with optimization level -O2, the system throws an unhandled exception during runtime.I’m using FreeGCC as the compiler (SPC5Studio environment).Has anyone faced a similar issue on SPC58 multicore systems?Are there any additional recommendations or known considerations regarding shared memory, cache management, or compiler optimization in this setup?Thanks in advance for any help or insights!

Moved  from STM32 forum - this is not an STM32 question.I am facing an issue with the Auto Dev Kit debugger. My previous license had expired (Hightec), and although I tried renewing it and even registered to get a new license, the debugger still does not work.Additionally, I notice that the debugger and flash icons appear greyed out.Could you please assist me in resolving this issue?

Hello, I am trying to use a HighTec Free GCC license with AutoDevKit Studio 2.6.1, but I cannot compile my project. Setup: OS: Windows IDE: AutoDevKit Studio 2.6.1 License: Free GCC Installed compiler: Only VLE compiler (ppc-vle-gcc.exe) is present; ppc-free-gcc.exe is missing Problem: AutoDevKit shows “No license for product (-1)”. Project’s Toolchain Editor only lists the VLE compiler. I am unable to add the Free GCC compiler manually because the executable is not in the installation. Request: Please provide instructions or a link to obtain the PowerPC Free GCC compiler (ppc-free-gcc.exe) compatible with my license. Guidance on installing and configuring it in AutoDevKit Studio so the license is recognized. Thank you.

The chip we are using is SR5E1E7. Now we want to know how to perform SWD debugging. We have tried various tools, but none of them worked.

I couldn't find the silk-screen printing instruction document for this model SPC58EG80E5FEC0X. Please help check if these two silk-screen prints are of the same model. Thanks a lot.    

When I use SPC5 Flash Programmer V2.8.1 to connect to the SPC56 CAN programmer, after configuring all the settings and clicking the connect button, the SPC5 Flash Programmer remains in a busy state and fails to establish a normal connection. Could you please tell me how to solve this problem?  Note: The operating system of my computer is Windows 10 64-bit. Besides, when I check the SPC5 Flash Programmer installation Details, it shows that the flash tool plug ins of STMicroelectronics are unsigned, Is this the reason why it cannot work properly? 

Hello,I am trying to run Projects\System\SIUL2\siul2LedBlink from StellarSDK_4.0.0 on a SR6G7EVBC4000P_RevA board. The project was successfully build. To flash the board in RAM, I am using the last version of Lauterbach. When running, it seems that it can't break on main.For testing purposes, I was running the sieve_ram_aarch32_arm_v8r_le.elf using the same Lauterbach script and the execution and breaking on main was done as expected. On a deeper investigation, I have found out that the .elf file form Lauterbach differs from the one build. Those differences can be seen below. Also, I have tried running an example from Lauterbach using the NVM, but I get the following error:  Do you have any suggestions to run Projects\System\SIUL2\siul2LedBlink on the board? Also, to flash an application on NVM and fix the flash programming error. Thanks in advance :grinning_face:

I need the BSDL file (Boundary Scan Description Language ) for SPC560B54L3C6E0X device, but I cannot find it on your web site. Can you send to me?NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hello,I have a problem regarding the slow initialization of eth1 on SR6G7 evbc6000 rev B board.The function xNetworkInterfaceInitialise() is failing multiple times, until it is succesfull.  From further investigation, I discovered that phy_check_id() is the cause of the failing. phy_check_id() is used inside dp83tg720_phydev_init(), which can be found here: ModExt/Drivers/Ethernet/DP83TG720/src/dp83tg720.c .Is there something that must be done before initializing the interface? Could it be a problem regarding the Ethernet cable?This behaviour can be seen using StellarSDK 4.0.0, using the ethPing project (Projects/Comms/Ethernet/ethPing). In order to use the eth1, in main() function I also registered the eth1 interface, like this: xNetworkRegisterIf(ETH0_INSTANCE, NO_HW_LOOPBACK);xNetworkRegisterIf(ETH1_INSTANCE, NO_HW_LOOPBACK); Thanks in advance! :)
