SBC mode not working #12

I have just bought Big Dipper board and I'm going to run it with Raspberry Pi i n SBC mode.

First of all, I replaced firmware for Duet5Mini+ suitable one, downloaded from Duet3d website. In no-SBC mode it was working fine.

For now I have tried to connect RPi using ribbon cable out of the box. And the Raspberry Pi does not recognize the board. After connecting to RPi's IP DWC throws an error "Timeout waiting for transfer ready pin", which I met when connection between original Duet and RPi is disconnected. To double-check all connections I connected original DuetMini5+ board and everything works fine.

At the moment I have checked that there is no signal on RDY pin (GPIO 22), so the communication by SPI is not starting up. After that, I suspect there is something wrong with the board. SD card slot on Big Dipper board is empty. I am using Duet-provided RPi card image.

I am not sure is there any jumper or MCU configuration causing it is not working out-of-the-box. I have checked Big Dipper schematics and I figured out there is only a buffer (supplied from 3.3 V got from RPi) between MCU out and GPIO port.

I have also tried to find out some similar issues but I figured out that SBC mode in FYSETC boards is not quite common.

Has somebody met similar problems?
