And now the board is compleatly useless...

This is almost exactly what I get when i use Bossa without removing the Erase jumper first. I am flashing version 3.1.1 so I get slightly different results:

After removing the Erase jumper, pressing Write again and then Verify, it works:

So please double check that you have removed the correct jumper:

I did not have the jumpper on, still did the reset and erase again and no luck

Looks like the MCU is not coming out of Erase mode. Try the following:

• Put the Erase jumper on
• Press the Reset button on the Duet
• Remove the jumper
• Press Reset again
• Reconnect Bossa (you can normally just click on the COM port dropdown and select the same COM port again)
• Ensure that Erase All, Lock and Boot to Flash are checked (but not the other boxes)
• Press Write
• Press Verify

The Write operation should display a progress bar and take 15 seconds or longer.

@dc42
Does not work

[dc42]

Are you using VIN power to the Duet, USB power, or powering it some other way?

[A Former User]

BOSSA just wont write.

And USB power

[dc42]

USB power alone may be insufficient. Please read the notes on avoiding USB ground loop problems at https://duet3d.dozuki.com/Wiki/USB_ground_loops and try again with VIN power. I assume that you have the 5V regulator on the Duet enabled.

Running on VIN and a laptop results in the same problem.

[dc42]

Make sure that the PC and the Duet PSU are plugged into the same power distribution block then. Usually it's not a problem if they are not, but occasionally a home has faulty mains wiring.

Not gonna risk it, unless duet waranty cowers a 5000€ pc.

What i have tried so far.
USB power only: Does not work
USB power only nothing connected exept the USB: Does not work
VIN and USB via a laptop: Does not work

Used the jumppers and reset multiple times.

Nothing works just like i expected.
