Re: Gpio works to flash initial firmware and then nothing
If it worked on the bench, then the unit works. If it then doesn't work in the vehicle, it must be the vehicle wiring that is causing the issue (as you suspect). Unfortunately, because we don't have that wiring in front of us, it's very hard for us to suggest what might be wrong.
I suppose if this was mine, I would first check:
- the power pin has 12V on it, and the pin is not pushed out of place in the wiring harness sides of the connector.
- the ground pins have less than 1 Ohm resistance to the engine block, and the pins are not pushed out of place in the wiring harness sides of the connector.
- the bootloader pin is not grounded - accidentally through a short, or through a wiring mistake.

Great, I'm glad it's working. We were all beginners at electronics at one time - and not so long ago for me! The more problems you encounter and solve, the more you will learn and become well on the way to being an expert.
