Hello everyone is max I ask your help to solve this problem:
I have an APM 2.6 I installed the version 3.2.1 firmware with hil simulation for testing.
the version did not work with my Xplane so I decided to reload the firmware from 3.2.1 quad mission planners to reconfigure my uav.
I realized that I can no longer load any firmware, the procedure is done correctly mission planner also makes verification but eventually only lights more the green light next to attack the gps but the APM does not respond and does not work.
I tried again to load the hil version to see how he reacted, it seems to work, however, the LEDs light up in the normal way even if I connect with mission planner and I go in flight data window with the apm device does not display nothing
