Remora - Rpi Software Stepping Using External Microcontroller via SPI

Sorry, I was confused in spi. I assumed that both board use same single spi without seeing it's board pin maps. But after seeing SKR3 pin map I found that it's using separate spi for config and comms. But in Octopus it's same for config and comms. Thanks for pointing out.

Thanks for your tips.

Finally I got TMC5160 working on Octopus pro board f446 version.
I have changed the spi to spi2 with new interrupt and uart to uart3. I choosen spi2 because it's on wifi connector on board which is at the edge of board, so there will be much shorter length spi cable required and it has uart3 at same place.
Thanks a lot
