some time ago I had a shortcut on my APM, and it stopped working.
here's the current behaviour I'm getting:
if I plug the power as usual nothing happens, not a single light shows, dead.
if I plug via the USB cable on the IMU, everything seems to work fine, all lights are on, code loads, MP connects ok, and CLI works.
with only AP board
if I plug the power as usual:
red power led lits
yellow mux blinks rapidly and dimm
blue PPM blinks rapidly even dimmer
What's the experts opinion???
is there a way I can power the APM from the IMU, as the USB does, I mean what are the pins that power the the APM from the IMU when using the USB?
any other ideas??
