Whilst uploading a sketch program to one of my Nano copies my Mac suddenly powered off. When I rebooted it the Nano USB/Serial Port was no longer recognised.
All of my other Nanos (same type are fine).
Today I decided to try and get this broken one working, I followed this guide:
But I have encountered several errors.
The first error was this one:
stk500_getsync(): not in sync: resp=0x15
After Googling this error I found this solution:
Placing a 10uf Capacitor between Reset and 5v then got me past this error but then led me to this error:
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
(as stated in the guide)
I amended the avrdude.conf file as described here:
But I still get the same error.
Any ideas or is this toasted??
