Duet3 MD6HC fw update fubar?
-
Normally you download the ZIP file that contains most everything and upload it to the Duet and then let the existing firmware deal with it.
Did you try that first?

I had the same issue with mine. The auto install through dwc failed and I had to update via bossa to get it working again

Maybe I should have pulled the zip file (Duet2and3Firmware-3.4.0.zip) from the git repo?
Yes that's the recommended way so that you have all required files.
Are you able to connect to the board over USB terminal and see if it will respond to commands like M115?

I also had mine (6HC) fail using the combined firmware when upgrading from 3.4RC2 to 3.4
The firmware was fully wiped and the board appeared as a BOSSA port. Fortunately I have a cable plugged in all the time in case I need to debug anything so it was a 2 min job to get back up and running. -
Mine bricked too 3.4 b1 to 3.4, but I connected with bossa and wrote successfully,
but then again no connection in YAT.
Whit wich firmware to update in bossa -

@jay_s_uk working OK now
thank you -
Thanks everyone for all the advice. I'll be spending time on the FW updates page today and hope for success. @Phaedrux - I connected the USB yesterday and I could see the device in Windows Device Manager, but it had a yellow-bang and I could not clear that with an attempted driver update. I did not look for the bossa port. I'll try again today, with both Windows (and maybe Linux) to see if I have better success.

I'm reconnected to the board, using a different (shorter) USB cable and now I see the bossa port. I'm proceeding to follow the bossa instructions.

Success with Bossa! Problem is SOLVED.
Thanks to everyone that offered suggestions.
