Cant unbrick thingsnode

[jonesro]

I cant seem to unbrick my thingsnode, i have followed the following instructions:
https://www.thethingsnetwork.org/docs/devices/node/troubleshooting/#:~:text=Plug%20in%20a%20USB%20cable,start%20fading%20on%20and%20off.
Making sure that i select the correct board SparkFun Pro Micro, but i get the following errors trying to upload a blank sketch:

Compilation complete.
Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding

avrdude: butterfly_recv(): programmer is not responding
Found programmer: Id = “”; type = v
Software Version = .; Hardware Version = D.e
avrdude: error: buffered memory access not supported. Maybe it isn’t
a butterfly/AVR109 but a AVR910 device?
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude: error: programmer did not respond to command: leave prog mode
avrdude: error: programmer did not respond to command: exit bootloader

any ideas what i should try next ?

Thanks
Rob

When you opened up the node and put it into bootloader mode (two slow presses of the Reset button), did the LED fade on and off, indicating that it was in bootloader mode (it only lasts 8 seconds or so)?

Note: If this doesn’t work, the bootloader would have to be rewritten with an external programmer. You can make one out of almost any convenient Arduino board, but may have to solder wires between them to rewrite the bootloader. This isn’t likely, but your answer will help narrow down the issue.

hi - well, yep, i have been getting the red fading light, and for two nights no joy in resetting it – but i have just been playing around with the timing of running the upload script, and must have hit the sweet spot-- ran the script just before sending the board into bootloader - and it has worked… so all good now … many thanks
