@dc42 I got lucky and happened to find another new cable I recently received. You were of course right and that fixed the issue.

Thanks for the assistance.

@dc42 I’ve tried 3 cables already with the same results each time but I’ll buy a new cable tomorrow and confirm if it’s still the same.

The cable I’m using right now is the one I’ve been using for all my embedded projects so I’m pretty sure it’s not the issue but you can never have too many good cables!

I tried to update my Duet3 board to 3.3RC1 today to take a look at it. The update failed over the browser interface and DWC couldn't connect to it afterwards. When trying to run the bossac update from the raspberry pi I can see the duet and get the info as shown below but writing a firmware file fails. (Freshly downloaded 3.2.2)

Has anybody seen this before?
