No OSD with NEXUSX target and Walksnail HD Kit V2

[joe8012]

Current Behavior

NexusX target. There is no OSD on the my walksnail HD vtx/camera from Nexus-XR flight controller.

Steps to Reproduce

1. Flash Nexus-XR with NexusX target.
2. Set Uart 6 (B) to MSPDisplayPort
3. Turn on OSD in configurator.
4. Set Video Format to Avatar.

Expected behavior

The OSD to work.

Suggested solution(s)

None

Additional context

I flashed my new nexus-xr with Inav target NEXUSX. I got video, gps, receiver connection and everything looks good in INAV, but I don’t have any OSD elements displayed in my goggles. The walksail vtx is powered from the battery balance port due to the restrictions of the nexus-xr. I wired my vtx tx/rx to port B(uart6). I tried reversing the tx/rx on port B. I tried running the port B ground back to the battery ground. In Inav, I have port 6 set to “MSP DisplayPort”, OSD turned on in Configuration, and video format set to Avatar. I tried port C(uart3). I tested the cable connections. I flashed inav 9 to a spare matek f722-wing flight controller and moved the walksnail hd to the f722 and the OSD works fine. I am sure my inav setup is correct.
