I'm a newbie with the pixhawk, please forgive me any obvious mistakes.
The last time I've uploaded my Firmware to the pixhawk the main LED stayed turned off. The FMU LEDs are always on and the IO LEDs stay on as well except of the blue heartbeat LED which blinks.
Since this happened I can't access the nsh console via mavlink.
I've used the pixhawk for several weeks and never had this issue. I tried to upload the default Firmware from github, but I still have the same issue.
Can you please help me with this issue?
Thank you very much
