[Bug] Parameters request fail on QGC

[deepboliya]

Describe the bug

I faced this issue on main at commit a2be919.
When I flash using
make px4_fmu-v6c upload and open up QGC after that, it says that "Vehicle 1 did not respond to request for parameters. This will cause QGroundControl daily to be unable to display it's full user interface. and hence Mavlink console on QGC is also not working. But I see the correct flight mode on QGC, which means it has successfully connected.

Which version of QGC is this? It looks like "Daily", is this a recent one?

[julianoes]

I just tested this on my end and it's working fine.

I built PX4 latest main (d88c86e) for Pixhawk 6C and I'm connecting over USB using QGC 5.0.8.

Have you made sure the SD card is inserted and working properly, and have you tried resetting parameters?
