Matek H743 - DJI OSD not working

General
1

Hi,

I cannot make my osd to work.

What I have:

  • Matek H743
  • Caddx Vista - connected to Matek 9v, G, TX, RX (video is working)

Configuration

  • SERIAL3_PROTOCOL = 33
  • OSD_TYPE = 3
  • MSP_OPTIONS = 0
  • SERIAL3_BAUD = 115
  • Custom OSD in DJI gogles set to ON

Any ideas what I can check?
Cheers,
Lukas

On this FC serial 3 is mapped to serial 4 in ardupilot.

so should be;

SERIAL4_PROTOCOL = 33
SERIAL4_BAUD = 115

read about mapping here Mateksys H743-Wing/SLIM/MINI — Copter documentation
