It sounds to me like the reset pin is being held high, maybe due to a short. And that is why the code doesnt start when you reboot. You could check the voltage on the pin with the programmer disconnected.

Nope, cable disconnected and it still doesn't work. I wonder if
something shorted on the board.

> In the messages you can read the exact pwm value of the throttle signal and put those in your airframe file as min, max, and neutral. Note that in your case min and max are currently reversed. Neutral is the signal it will send at boot and should normally be the same as min. Same with all other servos. Zero throttle should be configured to be a few clicks short of zero stick to ensure that off stays off.
