Where can I find the partition scheme of the boards?
On Windows and IDE 1.8, I can open %APPDATA%/../Local/Arduino15/Packages/esp32/hardware/esp32/2.0.5/boards.txt
and edit this file.
I added a new partition scheme there and removed the rainmaker (from every board).
When I open the IDE 1.8, I see the new scheme.
On the IDE 2.0, I still see the default partition schemes (even if I removed the rainbow partition scheme!).
Is the board info loaded from another location? How is it possible that I still see RainMaker if I removed it?
Edit:
Sorry, I read it now, that it is a caching problem (2.0.3 still has this problem):
The menu is cached. So you have to open:
%APPDATA%\arduino-ide\Local Storage\leveldb
and remove the *.ldb files inside this folder. You will loose all settings for the boards but the boards.txt will be reloaded (and cached again).
