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
