Hello, after successfully assembling and wiring a Voron 2.4r2 350mm from LDO Motors kit (revision D), I installed the software (raspbian lite 64b, then klipper, moonraker, mainsail and klipperscreen).
I setup Klipper (using the config provided by LDO), add the mcu path for the Leviathan board and the nithawk board, defining the printer size where nedeed, then restart the printer. But then klipper shows an error : Unknown spi_bus 'spi4'
I've search for hours in LDO githubs, leviathan github, forums, Klipper documentation, and I can't find what could be the source of the problem...
If someone can point me in the right direction, I'll greatly appreciate your help 🙂

You've mis-identified your mcus: your so-called main mcu appears to be an rp2040 and your so-called nhk appears to be an stm32f446....
