Hi,

Running the latest ardupilot version, using pixhawk 32 v5, the FMU B/E red led is blinking…

Any ideas why?

I don’t know what to do, I’ve tried everything, and what do we do?

No firmware or bootloader loaded maybe? Try using DFU mode to do an initial firmware flash.

But I’m not sure if I understood it correctly… I’ll look for the link in git to share with you. Let’s see if we can fix it.

I opened this yesterday:
