I have an APM with 2540 IC running APM 2.12 in a skywalker with Hitec Auroa 9 RC. The hardware is extremely unstable, APM is very frequently losing all configuration, about every 3rd flight. I have to resetup each time.
Now I am trying to fly Auto mode (which I have done many times previously), but whenever I select either AUTO or RTL the APM goes to loiter mode for both settings. When I check it on the ground in both 'show settings' and 'test:modeselect" it shows normal (and I don't even have a loiter mode set up as an option.)
I have airspeed and magnetometer and xbee installed, but even when I remove any of these componenets, I have the unstable situation of having to reconfigure APM about every 3rd flight.
When in show settings mode, the CLI reports CCC… at the mode, see screenshots:
I have reset the board and reconfigured numerous times, but it never becomes stable and the loiter mode has not recently gone away.
I have been using mission planner for all setups, but going back in to set modes in CLI. This approach does not use the reset button, ( only erase?) Is powering down/disconnecting power an adequate sub for pressing reset? ( have also tried using the reset button but that did not help).
