Can't upgrade past firmware 1.20
-
I don't have a Duet Wifi but I remember reading something about upgrading 1.19/1.20 that was different.
Here it is:
-
Download this zip file: Duet2Firmware-2.02a.zip https://github.com/dc42/RepRapFirmware/releases/download/2.02/Duet2Firmware-2.02a.zip
Extract it to a folder. Then use the DWC system tab to upload iap4e.bin and iap4s.bin, then upload Duet2CombinedFirmware.bin. It should prompt you to update the firmware. If not, you may need to rename the file to DuetWiFiFirmware.bin and upload it again.
If that works properly, you can then uploadNow that you have the main firmware up to date you should be able to use the normal full update method. Take the full 2.02 zip file that I told you to extract above, but this time just upload the whole zip file without extracting it. It should update everything you need to the latest. Same procedure going forward.

@Phaedrux I tried your procedure and it did the same thing: prompt for update, do something? then come back as 1.20. Is an older duet wifi incompatible, perhaps? I can't tell from here.
-
Can you copy and paste the version information from the settings tab as well as the result of an M122 diagnostic in the console.

Try updating to 1.21 first. If that doesn't work, try 2.0.
-
No luck on 1.21 or 2.0 using your previous technique
-
Try going through the fallback procedures described here: https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware

@planeguy said in Can't upgrade past firmware 1.20:
Supply voltage: min 1.6, current 1.7, max 1.8, under voltage events: 0, over voltage events: 0
I just noticed your supply voltage is really low. How are you powering the Duet?
-
I'm just plugged into the computer via USB right now. More importantly the fallback method 1 worked and got up to 2.0! 2.02 worked fine via the "usual" method after that. Thanks so much @Phaedrux !
-
Glad it's working. Be sure to check out the version release notes. A lot of things have been fixed and new features added since 1.18. Be sure to test your homing and movement carefully.
