Trying to compile Marlin 2.1.2 for Ender 3 SKR Mini v2.0 board

That worked for me! Wondering why this problem occured in the first place because i did not alter the build environment/firmware besides some configuration.h and configuration_adv.h tweaks. Also would there be possibly a downside to just using plane marlin with my configs adopted instead of the BTT forked FW?
