@bearer said in Duet3 - firmware update with RPi:
@Flex3D looks like you're still on the 3.0-beta12 the board likely shipped with, and its probably easier to connect the Duet3's micro USB port to the Pi and run the Bossa update, no need to disconnect the ribbon cable. The alternative would be to try and update to 3.0, them 3.1.0, then 3.1.1.
Seeing as you have functioning firmware (responds to M115) running the command below should send the command
M999 P"ERASE" command to the duet and start bossa to flash the firmware found in the reprapfirmware package.
(or if you have the Duet connected to the pi via USB just run
wget https://pastebin.com/raw/Wa1kYf3G -O - | tr -d "\r" | bash)
or follow the documentation.

I bridged the erase function like told in dozuki to reset it first and gave it a reboot. Than i connected the duet to my PC and it now has issues to identify the duet board itself. I bought a new usb micro cable too, to be sure but it's not working at all. Bossa shows me an error.
At least the blinking red light is off now but it's not possible to flash anything with bossa at the PC or to enter any G-Code...
