Uploading Marlin 2.x to Mega2560 not working

When I compile a simple program, it uploads to mega2560 without problems;
When I compile Marlin 2.1, the build goes perfectly - uploading fails:

I’ve tried different Mega2560 boards - same result.

How in the world does it suddlenly jump into the atmelsam platform from a atmelavr chip o_O. Can you open a CLI and do pio upgrade --dev and retry uploading?

Thanks for the fast reply !
Did the upgrade:

pio --version
PlatformIO Core, version 6.1.4a2

Same result - also added beginning of compile:

Could it be that something is wrong with my Boards List ?
Is there a way to remove and reinstall the boards list ?
(Board Explorer seems not to load)

5

Can you please remove all folders in C:\Users\lucka\.platformio\platforms and the C:\Users\lucka\.platformio\.cache folder and press the upload button again?

6

Super ! Thanks !
Removing the folder in .platformio\platforms did the trick !

I have this exact issue, it seems, but deleting the contents of the two folders mentioned does not solve it for me. Any help would be greatly appreciated, as I’m at the end of my rope with this one.
