SKR 3 EZ Firmware

Hello, I still don’t have a solution to my problem and I don’t know what to do next.

I’m looking for LR3 Marlin firmware for the SKR 3 EZ board. Does anyone have firmware for this board and can send it to me?

I’ve spent several days trying to program a firmware and I just can’t do it.

I hope someone can give me some tips to solve this problem.

Best regards
