All is good.
Installing the firmware with QGroundControl seemed to unblock whatever was stopping Mission Planner from accessing the FC.
I was able to connect to MP and everything is now working as expected/hoped. I even fired it up last night. Haven’t flown it yet as the weather has closed in.
I have the same issue with MP. You can load the APM firmware with QGroundControl and then use MP as usual AMP firmware will work with both. I alway load firmware with QGC and then go back to MP for flying.
Hello. Sorry if I suddenly jump in and asking you a bit off-topic, but can you elaborate your blown IO processor case?
My pixhawk also got solid red IO B/E light and quite hot especially on the co-processor. I’ve tried everything from firmware, bootloader, and dfu but at this time I’m convinced the co-processor is pretty much blown up.
Where did you get the idea I had a “blown IO processor case”?
No, it just happens that this particular version Pixhawk had orange LEDs whereas most have green.
I no longer have the Pixhawk. I had a flyaway moment and almost got it back when it crashed in really dense bush about 25 metres away from me. I tried for days but never found it.
Pity. It was my favourite drone.
Oh sorry, I was asking InsanitySquared specifically for the blown IO processor.
By the way, that’s quite a weird pixhawk you get there.
