After an attempted firmware upload today (using the USBasp purchased from Freematics), the OBD-II adaptor has stopped responding. Previously, firmware uploads have worked ok. Red LED is on when connected to power, have checked all leads between USBasp & Adaptor.
Error from Arduino IDE is:

avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

I attempted to check the status of the adaptor using avrdude at the command line as follows:

Code: Select all

avrdude -p m328p -c usbasp -v

Verbose Response was:

Code: Select all

avrdude done.  Thank you.

There are a few posts on this error on Stack Exchange and they refer to resetting the fuses with the programmer.
Does anyone know if this is the problem here? If resetting/updating the fuses is the solution, how should they be set?

thanks

Update. Tried reading the fuse bytes using:

Code: Select all

avrdude -p m328p -c usbasp -v -C ../etc/avrdude.conf -U lfuse:r:-:h -U hfuse:r:-:h -U efuse:r:-:h -U lock:r:-:h

Still getting the same 'target doesn't answer' error as before.

Edit:
I tried the same command with the same USBasp and cable on a separate Uno. It was able to read the Uno OK. So the problem is with the OBD-II device - it appears to be dead.

Any help please?
