Config Help for RPI4 + SKR E3 mini V2 + Remora or similar

Hello  everyone,
I need your help with my setup. LinuxCNC is already running on my Raspberry Pi 4, and I’ve also installed Remora. Unfortunately, I can’t find any information for my SKR E3 Mini board on where to connect the 5 cables coming from the Raspberry Pi. Somehow, I need to establish communication between the SKR Mini and the Raspberry Pi. The connections on the Raspberry Pi are clear, but where do I connect them on the SKR Mini? When I look at the source code on GitHub for Remora, I only find one entry for the SPI interface, but that seems to be related to the SD card. I’ve downloaded the pre-compiled firmware from Remora’s GitHub repository. Do I need to compile my own firmware to configure the SPI pins on EXP1?


It would be nice if you could help me further.


 

where was it before? I think the issue is resolved, we took care of it on github
