A couple of weeks ago on my copter’s maiden flight, I stupidly managed to let it get hung up in a tree. After it was retrieved I plugged in the battery and tried to fly it again but it would not arm. Eventually I noticed that the safety switch was flashing with four quick flashes followed by a pause and then repeating. Per the documentation this means that the FMU armed, but the IO did not. After attempting further troubleshooting I noticed that the power connector had ripped off the power module so the Pixhawk must have been getting its power from the ESCs. So, I replaced the power module but I continue to get the error code indicating that the IO board did not arm. Also the amber and blue lights on the IO side are alternating; the documentation says that this indicates a memory allocation error for developers and shouldn’t be seen by end-users.Image may be NSFW.
Clik here to view.Did I damage the Pixhawk when I tried to arm it when it wasn’t connected to the power module? The collision with the tree didn’t seem violent enough to cause major problems. Any advice on what to do would be appreciated. Thanks
