    • Newest OpenOCD fails with STM32L0

    Posted by tarek bouchkati on 2020-04-27 21:50 Tunisia

    Hi Przemyslaw ,

    the log you provided does not contain any error information. and you haven't described the unexpected behavior.
    Could you please give more accurate problem description ?

    The only hint that I can give you based on this log, is that your MCU is booting from system memory (bootloader) :

    target halted due to debug-request, current mode: Thread
    xPSR: 0xf1000000 pc: 0x1ff00288 msp: 0x200007a8

    So maybe you need to check the boot pins / option bytes.
    And if you have a flash programming issue, please provide a complete log with the error message.

    Note: the latest version of System Workbench is already one year old, so please consider using a new fresh IDE like STM32CubeIDE

    Kindly
    Tarek

    Hi Tarek,
    thank you for fast reply. After printing line:

    Info : STM32L flash size is 16kb, base address is 0x8000000

    there is a long delay (maybe 1 min?) and after that only two lines appear in console:

    Error: failed erasing sectors 0 to 0
    Error: flash_erase returned -5

    and "Terminate faliled" as well as:

    Error in final launch sequence
    Failed to execute MI command:
    load /media/DATA/ARMworkspace/temp_test/Debug/temp_test.elf

    Error message from debugger back end:
    Error erasing flash with vFlashErase packet
    Error erasing flash with vFlashErase packet

    alerts are open.

    I've checked BOOT0 pin - it's ok (0V).
    Also I've already installed newest CubeIDE - no change.

    Regards,
    Przemek
