Newest OpenOCD fails with STM32L0

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
