Hello community,

i reinstalled mainsailos on my raspberry 4 and get now the MCU Protocol Error. I tried to follow different guides how to fix this by recompiling and flashing.
In the pictures are my last atempt. I dont get any errors during the installation, but after reloading i still have the same MCU Protocol Error.

I ve set the "make menuconfig" to the correct processor model (STM32F446), i m not sure if Bootloader offset (32kib bootloader) is correct and on the communication interface (USB (on PA11/PA12)).

I appreciate any help : /

after one additional hour of work i was finally able to change the background of the error to black instead of red. PROGRESS 😭
