WalkSnail Moonlight OSD does not work with INAV 8

[boylect]

Current Behavior

Despite being enabled via Configuration tab, ports tab, and configured in OSD tab, the OSD will not disaply for the WalkSnail Moonlight.

Steps to Reproduce

1. Set UART to MSP DisplayPort
2. Ensure OSD is toggled on on Configuration Tab
3. Select Avatar on OSD drop down menu

Expected behavior

I expected to have an OSD

Suggested solution(s)

I reflashed my drone with BetaFlight and the OSD works. It just will not work in INAV8 (or in INAV 7.1.2)

I use IANV 8.0 with walksnail Moonlight, i have no issues and OSD works perfect. (tested with 8.0 RC and 8.0 official)

double check your wiring for walksnail, I find it unlikely that you got a cable that will workout of the box. You likely have to reorder some of the pins in the plug. If you pinned the plug yourself, you may have made a mistake 🤷
Worth checking

I did re-pin it. I have re-pinned and re-pinned numerous times of all combinations I can think of. Plus, it works in Betaflight.

I just chatted with someone who had the same issue on INAV with the Moonlight. He had to use a camera switcher and then change it from user 1 to user 2 in the modes tab. No further info on this, but have you heard anything like this before?

May be worth asking on the discord server

I dont see an issue with the config, for further testing i can suggest:

1. see if when arming the craft, does walksnail start recording?
2. on walksnail goggles, verify OSD is set to INAV or Auto (also, if you you using some custom font in the goggles, revert all to default)
3. try using different free UART port

[boylect]

I have tried at least 2 UARTs. I will check on the recording. OSD in goggles is set to AUTO. The thing that really throws me off is that everything works as it should with Betaflight.
