RC RSSI I/O FMU Not always displayed #20273

Open ryanjAA opened 1 year ago

On Main when RC RSSI is plugged in it doesn't always get picked up and displayed. Multiple reboots were needed to get it picked up.

Tested a known setup on a Pixhawk 4

@dagar explained that it is essentially a race condition between the i/o and fmu to pick it up and to possibly skip the rc_input running on FMU side.

Ideally it should be param that can be explicit. Attached is indicative of the issue:

So more on this. If I dont have RSSI and do a software reboot, it tends to come on after the reboot. Hardware reboot is hit or miss.

Occasionally it just works when powering it on but the software reboot seems to be the work around atm.
