Duet wifi 2 upgrading from 3.2? to 3.4 no dir called firmware
-
Hi all.
Juts in case anyone has the same issue, I was updating from a 3.2? version to 3.40 and it fell over during update (I copied up zip file using upload system files).
I had to use method of recovering of copying files manually to sd card and then upgrade firmware using M997 0 and then M997 1.
Error I got initially was
Error: M997: Firmware binary "0:/firmware/Duet2CombinedFirmware.bin" not found
The issue was there was no directory firmware on the sd card.
I created directory manually and copied system files and then was able to complete the tow M997 commands.Hope that helps anyone who gets stuck.
Not sure if I did anything wrong, but new directory may well catch out people as it did me! -
Normally the firmware directory would be created by DWC during the update. Something went wrong apparently.
Did you upload the intact zip file for 3.4?

@chapelhill that's likely to happen when bypassing firmware 3.3, which is the version in which the /firmware folder was introduced.

Hi I uploaded the 3.4 zip file and after 20 mins the process had not completed. I power cycled and connected using USB, the 3.4 firmware had loaded but presumably not the wifi firmware as it was expecting it to be in directory called "firmware" which did not exist.
I only read upgrade notes quickly, but did not see any requirement to go from prior 3.? version to 3.3 first, should have looked closer.
All working again, just posting to try and put some info in case others make my mistake.
Thanks for fab product and support.
