Duet3 MD6HC fw update fubar?
-
I think I did something stupid today trying to update my MB6HC board from 3.4.rc2 to 3.4.0, but I'm not sure what. Current state of the board is that the web page is not responding and when I try to connect via USB I get a windows error saying something is wrong with the USB.
I'm looking for some advice on recovery.
My update process - I downloaded two files from the git repo , Duet3_SDiap32_MB6HC.bin, and Duet3Firmware_MB6HC.bin. Then I connected to the board using the web interface and copied the files into the sys directory. I said yes when asked to install.
After this the web interface did not connect. Maybe I should have pulled the zip file (Duet2and3Firmware-3.4.0.zip) from the git repo?
I verified that the board was not getting a different IP address from my router and eventually verified that it was not asking for an IP address after the old lease expired.
I connected a USB cable to the board (no AC power) and windows said it could not connect to the board, even though the board did power up (LEDs on, BLTouch click/clack). I also downloaded the USB drivers and tried to update, but windows said the driver was already current.
I tried putting the 3.4.0 Sdiap and fw files in the firmware directory of the SD card and powering on. No change (still no IP)
I tried putting the 3.4.rc2 Sdiap and fw files in the firmware directory of the SD card. Still no joy.
Finally, I made a new SC card image with the config files I downloaded back in November when I first powered up the board. No change (I checked to see if it picked up a different IP on it's old MAC).
I'm looking for advice on what I should put on the SD card that should be a "sure thing".
I also have a PanelDu that I've never connected yet, but that seems like adding another piece of complexity. But maybe this is the best next step?

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

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 -
@martin7404 this one https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.0/Duet3Firmware_MB6HC.bin
make sure you tick all the boxes like shown below

@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.
