Re: Avrdude error when uploading

[Axel]

This sounds like either a hardware issue (wiring or somehow electrically
killed Nano) or the Nano has no bootloader installed.

The questions I raise in such a case:

1) Did it already work? (flashing the Nano)
2) If yes, what happened since it has last time worked.

Best, Axel
