I have brand new pixhawk 6c mini. After power on (by any source) B\E led in FMU frame blinking twice repeatedly. And all servo outputs not working (I checked it with different servos and oscilloscope).
For debug purpose I’ve flashed PX4 and B\E led blinking and servos works fine.
I’ve tried 4.5.7 and 4.3.8 versions. No difference. Bootloader is updated. I’ve read similar issues, but no solution found.
Here is video of LED status after power on:
