Debug error only at second session, but without even first run the program
Hello
I have a strange bug when I try to debug. The first time I can start (only start, not run!) the debugger. The second time I receive an error message when I start the debugger (only start, not run!) :
"Failed to execute MI Command. Error Message from debugger back end: Error finishing flash operation"
I have a very simple program with only three lines of code added:
HAL_FLASH_Unlock();
FLASH_Erase_Sector(11, FLASH_VOLTAGE_RANGE_3);
HAL_FLASH_Lock();
With the fallowing Code I can start the debugger multiple times without error messages:
HAL_FLASH_Unlock();
//FLASH_Erase_Sector(11, FLASH_VOLTAGE_RANGE_3);
HAL_FLASH_Lock();
The strange thing is, in don't run the program, so the Erase-Command won't erase anything.
Remark: When I debug when the error message appears, the code did not even reach the startup-code.
After the error message I have to erase the flash with the STM32 ST-LINK Utility.
I have an STM32F207ZG Nucleo, I use STM32CubeIDE V.1.10 with St-Link GDB-Server and SWD
Does anyone have an idea what steps I could do to get to the source of this error?
