The DIAG LED may light up dimly, or it may be off. If you haven't already, erase the firmware with a jumper as described in the instructions, before attempting to flash.

Ian

Already tried, might try again later.

@Mr-Yod I’ve updated the instructions to make it clearer how to erase, and the state of the LED.

Mr Yod

Ok: found the DIAG LED, it's dim but it's on.

And BOSSA stays on "Writing page 0 (0%)" without any progress...
But it's connected: "Device: ATSAME70x20"

Mr Yod

After more than an hour: still 0%

Mr Yod

YAY!
I managed to flash the firmware!

I had to buy a 75cm long micro-USB cable graded for 480Mb/s to be able to do it, but it worked!

Then I tried something: I loaded again the firmware zip file ad told to update (it already was at 3.5.2) and it bricked again forcing me to re-flash the firmware...

What version is/was your DWC running?

Can you re-download 3.5.2 zip?

Now it's 3.5 (it was 3.4.5 on the first brick but it was 3.5 on the second)

Can you re-download 3.5.2 zip?

I have only the uncompressed version, but I don't see how it can be useful, since it contains the same file I flashed with BOSSA.

You can only upload the zip file itself. DWC takes care of the rest. If you're uploading anything else that's probably the problem.

I always uploaded the zip.
I used the single uncompressed file only when flashing with BOSSA.

What browser are you using?

Mr Yod

@Phaedrux Web interface via Orca Slicer

Phaedrux

I'm not very familiar with Orca slicer. How does that work? It has a built in browser?

What browser are you using to upload the firmware zip file?

So it seems.

What browser are you using to upload the firmware zip file?

I told you: Web interface via Orca Slicer

Can you try chrome?

I could, but I don't want to risk another brick + reflash, sorry...

If I'll remember I'll do it in the next update.
