Hi,I was trying to program a SPC58EC-DISP board with a TCP code and after a while it turned on the red reset LED. After that, all my attempts to reprogram the board were impossible.I tried it with and without the jumpers of the JP5 connector, the configuration of the board with respect to the rest of the jumpers is the factory one. I even tried to keep the reset button pressed while trying to reconnect the board and modify the JP33 to try to get the connection with the PLS but I couldn't.I have 2 other SPC58EC-DISP cards with the same jumper configuration and I can connect with them without any problem, so I guess it's not software problem.Can you help me get the board working again?

I want to flash and debug using SPC5-UDESTK 5.02.04 on to the board SPC5746CBMKU6. This controller configuration is not given in the tool. So I have created new configuration for this board. Now I have tried to connect to target board. But it is failing to establish connection. Connection and power supply is good(Tool LED glows). May be problem with target configuration. Attaching failed report and new target configuration file(in .txt, as .cfg is not supported here). Kindly provide the target configuration file for SPC5746CBMKU6, if you have. Or suggest edits in current file.  

Hi I need to flash via CAN bus and I understood it is possible using SPC5-FLASHER on PC connected to the target via USB/CAN interface with SPC5_UPDATER_CONN=SPC5_UPDATER_CONN_CAN. But I need also to flash a target from another target with SP57xx so I would like to have the source code of SPC5-FLASHER crosscompiled for my target .. Is that possible?ThanksFabio

Hello,I am working with a LIV4F, and I am trying to configure the fix rate at 10hz like so:$PSTMSETPAR,1130,0x00,0$PSTMSETPAR,1303,0.1,0$PSTMSAVEPAR$PSTMSRRThe LIV4F responds with:$$PSTMSETPAROK,1130*30$$PSTMSETPAROK,1303*32$$PSTMSAVEPAROK*5CAll appears to be good. However, when analyzing the data, the update rate is much slower than 10hz, fluctuating between 3.5hz and 5hz. I can turn down the fix rate, and I get the expected results, but anything above 5hz does not work as expected.

Hi guys, I'm using RM0421 as reference for my develop work.But find some error in Chapter 5.1 Table 6.The end address of 256KB Code Flash block 4 and block 5 should be 0x0113FFFF and 0x0117FFFF.Is that correct? Kind regard! 

Hi all,I am using SPC582B mcu.The system timer is based on PIT0 CH0 (default choice) at frequency 1kHz.In the timer IRQ handler, I need to invoke SPI spi_lld_exchange API. Problem is this API doesn't complete, remaining stuck on the whileSPC5_SPI_WAIT_FOR_TXRX_COMPLETION(spip);   SPI APIs are configured synchronous: I already activated the preemptable ISR option in the configuration: Since I don't know if the priority level is ascending or not, I tried both priority situations, that is: System timer (PIT0 CH0) priority: 4                    DSPI0 priority: 10System timer (PIT0 CH0) priority: 10                  DSPI0 priority:4  Is these some configuration flag or API to call in order to make this SPI API working? Thank you all for any help or indication,FP

Hi, I have been working with the board for quite some time and everything was functioning normally. Last day, upon powering the board, I noticed that the board has entered reset mode. Also, I have been unable to establish a JTAG connection.Do you know the possible reasons behind this unexpected behavior, specifically the board entering reset mode? Are there some ways to restore boards functionality?Attached please find a picture of the board in its current state.

Hello community,An automotive client that i'm working with wants to devolope his own bootloader basing on ST bootloader on SPC5 product. my mission is to validate this bootloader on SPC5 eval bord of ST.So , im asking if there is a specific HW and SW tools to validate CAN UDS bootloder. Also any documentation about CAN bootloader could helpThinks in advance Farmer ST engineerZied ben Amira

How does one go about setting main() to address 8?Or any address, but I thought I'd be specific so I can see what the mechansim is to set things to specific addresses.  If you have a map input file (I see the out.map).Also, getting error:c:/spc5studio-6.0/eclipse/plugins/com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514/toolchain/bin/../lib/gcc/powerpc-eabivle/4.9.4/../../../../powerpc-eabivle/bin/real-ld.exe: build/out.elf section `.bss' will not fit in region `ram'c:/spc5studio-6.0/eclipse/plugins/com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514/toolchain/bin/../lib/gcc/powerpc-eabivle/4.9.4/../../../../powerpc-eabivle/bin/real-ld.exe: region `ram' overflowed by 3792 bytesNo idea where to look for the problem or how to correct.  Not new to embedded software and this is usually in some sort of linker file etc..usually can fix these things by a descriptive output file that fully describes the location and sizes of the code...but where...hmmm w

Hi Team,I am working on SPC58NN. Can someone help me in creating a motor control project in SPC5 Studio. If anyone has the documentation, Please share the link.Thanks and Regards,Akhilesh

Hello Team,I am not able to generate the code for the motor control application for SPC58NN board using SPC5 Studio.Please find the below snapshot of the same.Its generating the rest of the components except the motor control

Hi,      I am looking for the SPI Slave configuration example code for SR6P7G7C7 Controller.     Anyone please support on this Asap.   Thanks, Srinivas

To all community members, We are pleased to announce that we have created support for OpenOCD, a new programmer / debugger for SPC58x microcontrollers. The software is license free and you do not have any code size limitations! 8)The new dongle AEK-MCU-SPC5LNK is already available in stores!Within 2024, the dongle will be extended to SPC56x microcontrollers.Go check it now! Best Regards. AutoDevKit Team

Hello,  Does anyone have more information on the hardware/software setup regarding Application Note: AN4353. I understand the rough software architecture for how this is supposed to be implemented but I dont see anything pointing to examples or supported toolchains for debugging.  Sorry if this is a novice question, but I am looking for something to use for debugging besides PLS UDE and OpenOCD based StellarLink. Thanks!

Hi,I would like to check if STM AEK-POW-BMS63EN board can be used as a first board in the daisy chain with the setup where we have external MCU (for example STMF103RB) and AEK-COM-ISOSPI1?In the datasheet you describe difference between 'Master' and 'Slave' in the following way:and all your AEK-POW-BMS63EN comes with SPEIN pin pull-down via R20: Can you please clarify if the usage of AEK-POW-BMS63EN in the single BMS setup with external MCU is even possible?BR,MaraLo

Dear community members, In the AEK-POW-SPSB081 board, the SPI pin labels (red box in the below image) are not matching the labels of the test points. The correct labels are those placed on the test points (green box).   Thank you for your contributions. Best Regards, AutoDevKit Team  

"Hi,We are building hardware with the SPC58EG80E5 MCU. For debugging purposes, we plan to use the UDESTK-EVAL kit. However, on the product page, it states that it is "not recommended for new designs." What alternative options can we consider?"

Hi, I am using L9663, can you send me a driver code? Or a schematic diagram of the wiring

Hi,I'm trying to understand SPI communication for your L9963E.In the data sheet for your L9963E IC is missing the definition of how SPI shall be configured. It doesn't say anything about MSB/LSB bit send configuration for SPI. In the picture below we can see that you have defined the order for IC frame which seems to mismatch with the actual code. From the picture below we can see that CRC should be sent the first in the frame, but in your source code in AutoDevKit Studio, CRC is packed the last spiWord[4]. Probably I misinterpreted your IC frame definition or example code.Can you please explain the right order for both receiving and sending SPI frame, as well as, how should SPI be configured?
