Hello, i justed updated everything on mainsail for my voron so naturally i got the mcu firmware message. I have a raspberry pi 4 and spider board. Im following the procedure listed on vorons website for SSH updating and its not working. I get failure to connect to MCU when using ./scripts/flash-sdcard.sh /dev/ttyAMA0 fysetc-spider-v1 so i believe it needs to be modified for my current setup but i am not clear on it. Any help would be great.

As the error says, you did update the host (the rPI) but have one of the rare cases where you also need to flash your mcu new

One simple question if you follow instruction of the Voron discord, why not simple ask there. It seams that these are outdated
