RRW Lab SPI with raspberry pi 5

Hi, I’m new to linuxcnc and I am trying to get the rrw lab board to work. I’m trying to use the SPI sd card firmware with an STM32 Blackpill. The blackpill led is flashing, but there’s no connection. I can’t seem to find anything online about setting up SPI with a pi5. Any help would be appreciated. 
Thanks.

I tried Googling the RRW lab board and all found was this thread.

Can you link to a product page or give is more to go on?

Do you have a driver for it?

Is it this?  github.com/cakeslob/RRW_LAB
google does not find it but duckduckgo shows it first

Might be worth asking in the Remora thread.

Yeah that’s the one
