Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed

Describe your issue:Im trying to use a pico as a secondary mcu for an adxl. But i get this error “adxl345: spi pins must be on same mcu”. I followed this tutorials https://www.youtube.com/watch?v=W_VHbT_tsZw and this one https://klipper.discourse.group/t/raspberry-pi-pico-adxl345-portable-resonance-measurement/1757

If i comment all but mcu line i can see my pico in ratos web UI, if i uncomment all i get that error. How i can make ratos to forget the rpi spi pins and accept those from pico?

Try moving the [mcu pico] section above the [adxl345] section and remove the adxl345_* aliases there.

If this does not work, you should probably address the issue in the ratos community. In my opinion the ratos configs are completely over engineered making it virtually impossible for regular users to work with it.
