Uniti Firmware Update; "A communication fault occurred while reprogramming the ARM processor......."

Ps.

I disconnected and reconnected ethernet cables on both computer and Uniti.

This time it got as far as 68% before failing.

Very frustrating.

You could try disabling the antivirus on your PC in case that is causing an issue.

Apart from that you could ring Naim Technical Support and see what they suggest.

I suspect that your Uniti won't now work, so I don't think it can do any harm to restart the Uniti and the PC and try again.

The other thing to mention is that you need two connections with your Uniti, a USB connection to the mini-USB on the back of the Uniti and an Internet connection, preferably Ethernet. It won't work without both.

The reason you need both is that part of the update is delivered through the USB connection and the other part through the Ethernet connection.

You don't need the Internet connection per se, but both your PC and the Uniti need an IP address and a way to talk to each other which is the Internet router normally.

Thanks for the replies.

Yes, I have both connections. Mine is actually USB/R232 coz it's an older Uniti. (Also, Windows 10 x64, for what it's worth.)

Why the Firmware can't be downloaded prior to installation in this day and age is beyond me.

Thanks again.

Turned off all Start Up items via Task Manager and just tried again; got to 97% before failing.

Frustrating doesn't begin to describe it.

Uniti is dead as a dodo now.

I can understand your frustration but I'm not sure what else to suggest. This update procedure usually works without problem (which doesn't help you of course).

I would ring Phil Harris at Naim technical support. He might have a suggestion (he can also log into your PC remotely to try to help if you want.) He might pick up this thread but doesn't monitor all of the forum all of the time.

Otherwise it's try another PC or go back to your dealer.
