No Mav Data on MinimOSD

I am using a Pixwawk Lite for my FPV rig. I have not had it going since last fall. No problems with the OSD. I am now finally getting it together. I upgraded the firmware from 3.2.1 to 3.3.3 and now I get NO MAV DATA. It flashes my call sign every so often but no data. I have read lots of things to try and tried them all except going back to an earlier version of the firmware. Is this related to the firmware. All the hardware seems to work like it’s supposed to.
Thanks

What telem port are you using for your OSD. Maybe the port configuration got reset.

I’m using Port 1. I’ve tried changing the parameters.
Thanks for you reply

Telemetry works fine

I have another OSD that was on another rig that I had not hooked up yet and swapped out the one that gave me no mav data and it works great. So I guess the problem is in the OSD. I’ll do further testing to see if I can find the problem.
That answers my question.
Thank you
