Avrdude not in sync errors attempting to update emonTx firmware

I’ve changed the reset GPIO pin to GPIO12 (BCM 18) in the autoreset file in /usr/bin/ and connected up the appropriate wires.

Obvious question, but you have connected the rst pin to that pin on the Pi?

@borpin

You need to edit the file /opt/openenergymonitor/avrdude-rpi/autoreset and change the pin number to 12.

I edited a different file when I did it.

Did you stop emonhub first?
