  • [ABANDONED] STM32CubeIDE and J-Trace not working as expected

    I have had a lingering issue that rears its ugly head from time to time and is a huge productivity killer. I honestly cannot say what triggers the issue, or how to fix it. It is becoming too big of an issue to continue development with the system like this.
    Hardware used:

    -STM32F746BG
    -Seggar J-Trace (SWD @ 4000kHz) or ST-Link
    When using my J-Trace from within STM32CubeIDE I get this output in the console window:

    If you look at the J-Trace log, clearly the verification of the downloaded bytes is failing, why is STM32CubeIDE telling the J-Trace to write to address 0x00008000? It looks like this address has been shifted right 3. The normal programming address is 0x08000000. Super strange and I have no idea how to fix this problem. In total this has probably caused me 2 weeks of development work dealing with it on and off, losing work as I am forced to revert to older code bases to get away from the issue (sometimes even this doesn't help), like right now, im too far off in a branch to revert, I would lose a months worth of work.

    I have noticed that the log says, "SEGGER J-Link GDB Server V6.62 Command Line Version" but I have installed V6.64. How would i go about updating the STM32CubeIDE's version of the j-link GDB server?

    I seem to be able to manually flash a bin or hex file with my J-Trace without issue using the J-Link Commander application provided by Segger. Also other projects work while this one is failing.

    Help would be appreciated here, every minute counts as my project is on a stupidly strict schedule.

    Regards,

    James
  • You could check it either with flashing via gdb, look at "readelf -a your_file.elf | less" if the sections are at right address or trying the stm32loader. The stm32loader expects that you have UART connection to the MCU and that MCU is in bootROM mode (stm32loader can pull the bootROM-enable pins if you have configured it and have them connected, or you connect the pins manually). STM32CubeIDE also uses the same way if you flash via UART.

    With stm32loader you can specify the address manually with -a option (which defaults to 0x0800000) which could avoid your predicament. Converting .elf to .bin can be done via "arm-none-eabi-objcopy".

    OpenOCD could be an option, but for me it never worked with JTrace.
  • Hi James,

    This is how we tested CubeIDE and it worked for us:
    wiki.segger.com/STM32CubeIDE
    Did you setup the CubeIDE like this?

    If I understand you correctly, this issue is not occurring consistently. Correct?
    If so, then it is most likely a CubeIDE issue.
    I would suggest to contact ST about this.

    Best regards,
    Fabian
