Firmware recovery with an SBC
-
Hello Duet3D forum,
I have a Duet36HC running in SBC mode that seems to be dead after a bad firmware flash. Is there a way to re-flash the firmware from the SBC? The directions fallback directions do not seem to line up with the layout on the Pi.
Thank you

How did you update initially? When using the SBC option you should be using sudo apt update and sudo apt upgrade from the Pi terminal.
Do you still have access to DWC? If so, you can try sending M997 to reflash.
If you don't have access to DWC, you can disconnect the SBC, and connect the board to a PC via USB cable and use BOSSA to reflash the firmware directly.

You can then use YAT terminal to verify if the firmware has been flashed.
Once you are back up and running on the SBC, use M122 to check that the firmware and DSF version match the expected version you've flashed. At that point it may be good to try the sudo apt update and sudo apt upgrade again to ensure it's working correctly now.

@Phaedrux I don't have access to the DWC. I'll follow the steps below. Thank you.
