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 

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 accessib

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 :

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

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,

Hello team,I am using the GUI demo (single) for BMSCCTX and C4MINI with 4 LFP Batteries. I have followed the steps described by @ritehracingteam in this thread.After I run the program from the AutoDevKit Studio, my D9 and D2 LED are lit up and D8(Blue) is blinking. D7 remains turned off. Which according to the documentation means SPI is not working.I made sure Hotplug connection is made and the pin configuration is correct, also checked all the connections.Is there something I might be missing?Regards,Zen

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 appl

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)

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? 

Hi team,I have seen example of C4MINI1 daisy chaining BMSCCTX with BMSCC which is working fine.I have 2 BMSCCTX, so i was wondering that i can connect 2 BMSCCTX for daisy chaining with C4MINI1.But i have noticed that in the datasheet of CCTX, the daisy chain receiving pins are not mounted inside,(which is mounted for BMSCC only. So does it mean i cant use 2 BMSCCTX as node and use dual access configuration?Can anyone explain about this please.Thank You.

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.
