Hello,
my Pixhawk keeps freezing after some seconds to minutes after powering. The mail LED stops in its current state and only the two power LEDs are on. Before the freeze the Pixhawk works completely normal, but then the B/E and ACT LEDs are blinking in a different way for a second.
This pixhawk was not used a couple of months and now its not working anymore??
I also loaded some old firmwares of ArduCopter and ArduPlane, formatted the SD-Card, but the problem persists.
This problem is also independent to the power source. I also set the logging to always and the log file stops abruptly.
