Hi.
I’ve had this issue twice recently. New boards working perfectly, but after numerous flight time, at next boot up, craft remains in pre arm error.
Plugging into pc shows error as baro driver not initializing.
But it was working before.
Discussed with FC manufacturer and they agreed baro is defective.
I tried the dev4.1 firmware as suggested in previous reply with no change.
I tried loading qgc firmware which did load, but then reported baro missing.
Is it possible that after numerous landings the baro can detach from the FC surface mount board?
Thx
Gary
