Hi, I am looking to use AEK-POW-BMSWTX battery management system for EV related battery management experiments. Please let me know if I can use AEK-POW-BMSWTX with STM32 microcontroller boards. Also please let me know if any other boards are required to perform experiments with AEK-POW-BMSWTX. Thanks and regards

Dear Community,I have a general question. I wanted to use C++ classes in SPC5 Studio to get a cleaner project structure.For this, I changed main.c to main.cpp and included the C headers using extern "C". I also enabled the C++ linker in the Platform Component RLA.The project builds without any issues, but the parsing errors in the editor are extremely annoying. A lot of the code is marked in red even though it compiles fine.Does anyone know what setting I need to adjust to get rid of all these unresolved reference errors in the parser (i presume...)?Kind regards,TKorn

Dear ST Community,I recently bought the SPC582B-DIS board in order to test the EV-VNF1248F board. I installed the VNF1248 Evaluation board GUI and the UDE STK 2021 by following VNF user guide.I downloaded the Chorus1M_VNF1248_discovery.elf in order to test the board, I flashed it with this elf file (flash success) but communication is not possible in the GUI with the good COM port  and good serial configuration (error "Cannot found Demo Board! Check USB cable"  in USB FTDI, and no Rx trame in Serial Port)I tried with another computer, same results. I looked in the forum, I have the good PLS driver (Driver USB PLS\JtagUsbDriver), and I installed the stsw-link009, but still not working.I also found another elf file on st community website --> Chorus1M_M09SpiDriver.elf, and with this .elf, I'm able to communicate, I get Rx trame and uC is active, but I get the error "firmware is not fitting with HW type", which seems logical.If I'm not wrong, I (and anothe

According to a Blogpost regarding the the TeseoVI series from February 2025, ST has already released the TeseoVI family chipsets ("ST is launching today the TeseoVI [...]").Yet, as of January 2026, neither the chipsets, nor the modules or the Evaluation boards are available anywhere.What's the state on the actual release/availability on the TeseoVI modules/devboards?When will at least the evaluation boards be available?I'm specifically interested in the Teseo-ELE6A.

Hi,On the SR6P3C4 page (https://www.st.com/en/automotive-microcontrollers/sr6p3c4.html) there's a databrief. But not much about a datasheet, specification, or any deeper information about the modules associated with it. Is there a way to access those?Also (still related to the first question), the data brief does say something about maximum junction temperature of 165C, with a note:Nominal specification up to 150 °C. Delta specification up to 165 °C.I'm not sure to understand what does the delta specification means.Thank You

Dear ST Team,After successfully setting Teseo-VIC3DA module, we can get message 3 digital axes accelerometer($PSTMDRSENMSG,30) and message 3 digital axes gyroscopes($PSTMDRSENMSG,31) which are returned from Teseo-VIC3DA HW at 15Hz speed. However, 3 raw data raw_x, raw_y, raw_z are unstable eventhough Teseo-VIC3DA is standstill.For more details, please help to refer to 2 attached logs: PSTMDRSENMSG_30.log and PSTMDRSENMSG_31.logOur question here is: why can we not get stable raw value? Do we miss any setting for getting such stable value? Please kindly help to support. Thank you. Please note that, we use below settings:"$PSTMSETPAR,1228,0x2000,2*46\r\n"; //Disable $GPGBS"$PSTMSETPAR,1228,0x40000,2*70\r\n"; //Disable $PSTMODO"$PSTMSETPAR,1228,0x800000,2*4C\r\n"; //Disable $PSTMDRGPS+$PSTMDRSINT+$PSTMDRCAL"$PSTMSETPAR,1228,0x20000000,2*46\r\n"; //Disable $PSTMDR1+$PSTMDR2"$PSTMSETPAR,1228,0x10000000,1*46\r\n"; //Enable $PSTMDRSENMSG"$PSTMSETPAR,1684,10*11\r\n"; //Set speed

hi community  i am using  "AEK-AUD-C1D9031"  board. in this board i had flashed  .WAV files and i had played. the wave files are played using an example code given in the autodevkit. i used an API playsound() this one will give good sound when i had used playsoundwithgain() -> the gain with range (15,17) the sound quality was good with decent amount of volume. but hear i want to control the volume  (0db - 75db),but by using playsound() and playsoundwithgain() i am unable to control the volume( the sound will be very noise when i had used gain in range of ( (0-14) and (17- so...on) ). so is there any alternatives to control the volume of the sound.   hear is the pic of the function which i had used.

Dear St's engineers,I am encountering an issue with the GNSS TESEO VIC3DA module regarding the inability to enable the PSTMDRCAL message output. I have tried the command $PSTMSETPAR,1228,0x800000,1*4F (as described in the CDB table 228, which is used to enable three messages: PSTMDRGPS, PSTMDRCAL, PSTMDRSINT), but as a result, only PSTMDRGPS is being output.

Hi Sir,  Pls advise who are in charge of crystal or OSC for STA9100MGA, I want to know crystal/OSC part num and crystal/osc spec. Tks! Regards, Brandon   

Since STA8135G is a triple-frequency GNSS chip, its hardware should have the capability to decode the E6 HAS message. However, I can't find related message from its RTCM output. I have searched the web and was informed that it can be supported by upgrading to certain firmware, named Measurement Engine (ME) Firmware. Can anyone help to tell me where I can find the suitable firmware, and whether I can do the upgrading and make my chip a more precise one? 

Hi, I'm using SPC560D-Discovery and want to boot it via UART: I've closed J12 and J13 according to the UM1681 and then powered on the board. Since SPC5FlashProgrammer is not supporting SPC560D I connect and send messages manually with Python. According RM0045 I've set UART for 19200 baud rate (SPC560D has 16MHz osc) and sent the password, but the uC answered me with every second byte and I definitely see that with logic analyzer: 13:42:46.503 -> FE EF FA CE CA FE BE EF | I've sent 13:42:46.518 -> FE FA CA BE | response from board  While according to the RM0045 it should echo the whole password. Same happens when the address is sent: it echoes only every second byte.Should I use other baud rate or should I start with some message for auto baud? How can I understand that now uC in auto baud mode? 

Hi Members,The EV-582B board seems to be out of stock within numerous distributors (Mouser/Digikey...) and no release date in sight.May the available SPC582-DIS replace (as both share the same microprocessor) and be reprogrammed with the already compiled Chorus1M_VNF1048_discovery.elf/Chorus1M_VNF1248_discovery.elf firmwares (with some rewiring between the mother and daughter boards if needed)?A better solution would be to publish the source code and leave the customers compile it on wathever SPC5 motherboard they own. It has been asked numerous times in the VNF1048F posts but STM does not seem to hear our voices.Hope we will get solutions soon as ST members seem reluctant to answer (7 posts under 10 about the VNF1048F without answers... my 2 cents!).Regards,Michel

Hello, I have been trying to make the AEK-MCU-LNK work with my SPC56 discovery board with OPENOCD (I reached a dead end trying to make the .cgf files). So I have two questions:1.- I understand that the AEK-MCU-LNKU works with this SPC56 family using UDE. Is that true?2.- I saw in another post (https://community.st.com/t5/automotive-mcus/stellarlink-vs-spc5-udeskt/td-p/64794) in the last answer, that AEK-MCU-LNK with the UDE driver should work with SPC56 family. Can you please confirm this?Thanks,Agustín

Hello Community,I would like to understand in general how to activate a peripheral interface such as CAN or FlexRay on the SPC58 platform.I have looked at the example projects and identified a few required steps.However, I would like to confirm whether I covered all major points needed to enable a peripheral.Configuring the PinMux using the PinMap editor → connecting the hardware pins to the selected communication interfaceEnabling the peripheral clock using the corresponding PCTL indexIs this enough to connect the hardware pins to the selected communication interface?Thanks for your help!Best regards,TKORN

Dear community,I am currently working on the FlexRay driver and wondered, where do I have to put the base address?In my opinion, it seems that I have to lay the base address in the system RAM area. I therefore found System RAM 1, which has a lot of free storage. Is this the right approach, or where do I have to lay the base address?Thanks in advance.Best regards,TKORN 

Hi !We are using an SR5E1E7. We want to put it as LockStep (both core and dma).So we have to setup the register 'Global System Configuration' / SYS_CFG_REG.We seen that we need to use the DCF.Do you have any example / file to setup this mcu like this ? We couldn't find any document on the web, execpt the MPC5xxx DCF configuration from NXP.Here some question we had:- How can we calculate this ? Have you any DCF configurator xsl like NXP are doing ?- To set the Cores as Lock Step and the DMA as Lock Step, we need to only write to the 'Core Enable and LSConfiguration' of the DCF ? With the value being the one we want in the 'Global System Configuration DCF' with the exact same mapping. '0b00000000000000010000000100000011' in our case, all core enabled and all lock step set- Does this step can be done at runtime ? By directly addressing the adr 0x1FF80398 ?- Or is this only accessible during JTAG programming ? So we can create the dcf_map in a specific .dcf section that will

Hello, I am using SPC582Bxx controller. I want to configure software watchdog timer in my project. How to add that SWT. Currently I'm using autodevkit studio for software development. Please tell me how to configure that?Thank you,

Hi Team,i am working in the daisy chaining bmscctx and bmscc using a Pi MCU. I was able to get the values using only bmscctx.now i am having issue when i connect the bmscc also.the problem i find is in the user manual3185, the figure for daisy chain is given as:and it says to connect ISO Hp to ISO Lm of the next node (that is opposite polarity).but when i looked in the L9963E datasheet, it is given as :Here ISO HP is connected to ISO LP (that is same polarity)so my doutb is which among the above should i follow. And due to this i think my values after daisy chain is not displayed.My second node is not assigning as my daisy chain is not configured correctly.( i am using mcu as pi btw)Thank You.  

Dear community,I am currently working with the SPC58 E-Line processor placed in the mother daughter evaluation board.I am using the AEK-MCU-SPC5LNK with OpenOCD. The reference manual for the E-Line is similar o the G-Line. I have only found the SVD file for the G-Line, so I therefore thought, that using this SVD file could work. Sadly the peripherals remain blank and I cannot see any memories.I would be very happy if someone could tell me, how to get the correct SVD file or what do I have to change to get it running.Kind regards,Tassilo P.s I have used the attached manual, to access the peripherals: How to use the AEK-MCU-SPC5LNK programmer and debugger for SPC5 automotive microcontrollers - User manual

I'm working on a battery management system using an STM32F302 going to an AEK-COM-ISOSPI1 dev board using the L9963T transcevier which is daisy-chained to 10 AEK-POW-BMS63EN boards using the L9963E chip.The problem that I'm having is that when I send a message over the ISO SPI lines, it adds an additional 0 before it sends the message.I have attached two messages that show the leading 0 bit that is added. msg 0x55 55 55 55 55 and msg 0xFF 00 FF 00 FF. SPI settings are8 bits frame MSB first Baud rate 1000 kbits/secCPOL lowCPHA 2 edgeCRC Disabled How would I go about removing the leading zero from the message? Any help would be greatThanks

How can I boot my own application on sr5e1?I read about DCF and BAF but it is not really clear what I need to do in order to let my code run out of power on.Any hint/guidance? Cheers

Hi,I'm trying to figure out what to expect for current consumption for the SR5E1E570C30F01X. The datasheet DS13808 - Rev 8 - November 2025 notes under "3.7 Device consumption" that "The following table [table 10] reports each single contributor factor to the device consumption. Refer to Figure 3. Device consumption measurement to see where each contributor is measured.". However, upon inspecting figure 3, it does not contain the required information. Notably, I_DD_HV and I_DD_HV_SMPS_LKG are not shown in the figure despite their grave importance. In fact, only two of the currents listed in table 10 are depicted in figure 3.Is there a corrected figure or information on calculating the approximate total current draw of the MCU - does the I_TOT calculation under 3.7 truly represent the total current draw, including both the HV and LV side? This is presented in a very unclear way.Thank you

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.
