Flight Controller Booting issue

ArduCopter Copter 4.6
1

I have been facing issue in couple of Pixhawk FMUv3 flight controllers. Initially the copter will be working smoothly and out of the blue the flight controller can’t boot. USB port can be seen in device manager but mission planner would be unable to connect with the FC. This is happening with all the firmwares above 4.5. When I load 4.4.4 or any other below it, then again the flight controller will start to boot. I am currently taking multiple flights in 4.4.4 just to see if same thing happens after couple of flights. But would be interested to hear from you guys.

For your reference I have attached log after which I observed this booting issue here.

Remove the link access requirement for assistance.

Which Pixhawk Flight Controllers?

Hi Dave,

I can remove the link access but can’t upload the log file directly as it is >8MB limit.

This happened in two Flight Controllers as of now and in both Radiolink FMUv3 2.4.8 is present. I even checked whether 4.6.3 gives support to Radiolink and it does.

That’s what the link is for.
I think the only Radiolink product with real support is the Pix6. And because of this I would not use any Radiolink product:
Radiolink Bad Actors

That said those 2.4.8’s are likely just generic versions like all 2.4.8’s. Not a good choice in any case.
