Solved Beta 3.4 Toolboard 1.1 firmware update failed

[dc42]

@pakue please try a factory reset of the tool board, by holding both buttons down while you turn on the power. After the blue VIN and red 5V LEDs on the tool board are lit, you can release the buttons. The tool board should attempt to download firmware from the main board. If it fails, the STATUS LED should flash one or more error codes.

@dc42 Sorry, I forgot to add that to the post. Yes I tried that without success. The error code of the LEDs is:

long red, two short red. Afterwards the green LED flashes briefly, not sure if that is part of the error code.

@pakue please count the red flashes again, because 2 long/2 short doesn't make sense.

The green LED flashing normally means the board is asking the main board for firmware.

@pakue what does it do after the green flash?

[Pakue]

@dc42 No further flashes.

@dc42 Is there serial output on some test points that would help in debugging?

[dc42]

@pakue I think we had better replace your tool board. Please email warranty@duet3d.com with a link to this thread.

Which country are you in?

@dc42 Ok, I'll send an email with my infos.
I'm located in Germany.

@dc42 I received the replacement board. Thank you for the quick help!
I'm guessing I'll wait with the firmware update until you had a change to look over the defect board?
