I think i’ve seen this issue before but I cannot find any documentation about it.
I’m having a usual setup. Matek H743-slim + frsky r9mm receiver.
The receiver is connected to TX6(Serial7) and is operating with Fport.
After installing Arducopter 4.0.7, I’m seeing that fport is working and all of the channels are moving except for Channels 1-4.
When I’m mapping THR, YAW, PITCH and ROLL to a different channel, that channel will not work as well after a reboot.
I saw the same results after swapping the receiver to frsky rx4r with sbus. same, Channels 1-4 are not moving.
Any help would be appreciated, thanks!
