Pixhawk 4 mini MSP protocol for osd

Hi,

my setup : pikhawk 4 mini : arduplane last master version
crossfire nano
DJI HD FPV
I’m using the nano arduino to get the osd working with the DJI google.
I saw that it’s possible to get it working directly with the last ardupilot firmware activating the MSP parameter.
i tried but i don’t see any osd parameter in the firmware…
what 's wrong ?

Thanks.
Pascal

Best to head to discuss.ardupilot.org and ask the ArduPilot folk about that one.
