ST Nucleo F091RC Restart Failing With An Error

Advanced Solutions Debugging
1

Hi, I’m using Core 6.0.0a1·Home 3.4.1. Every time I am debugging my ST Nucleo F091RC and I try to restart, I get the following error:

*** [.pio\build\debug\firmware.elf] C:\Users\username\Documents\PlatformIO\Projects\Embedded Drivers\.pio\build\debug\firmware.elf: The process cannot access the file 
because it is being used by another process

The full log:

The terminal process "C:\Users\username\.platformio\penv\Scripts\platformio.exe 'debug'" terminated with exit code: 1.

I’m not sure where to even start with this error. Any help would be appreciated. Thanks!

Either PIO / the debugger, or another VSCode extension, doesn’t “let go” of the firmware.elf file as it is held in the debug session while a new version of the firmware.elf is recompiled.

Please report to Issues · platformio/platformio-vscode-ide · GitHub with the offending project + reproduction instruction.

I was directed back to the forum by @ivankravets . Not sure if I can bump this thread but any help would be greatly appreciated. Thanks!

Is there any way to move this thread to the “debugging” section? Maybe I can get some support in that section instead.

Thanks!
