Hi All, I try to upgrade my older Prusa i3 from 8-bit mainboard to the SKR mini 1.1. I re-used the RepRapDiscount Smart Controller LCD for my displayer. I cloned the latest repository here and compiled the firmware.bin file by VSCode, I put the bin file into SD card and power on by 12V but nothing happen. There is only red light on on the board, my LCD didn't turn on. How to make sure the problem is firmware or hardware problem?

My mistake, just switch the EXP1/EXP2 lines
