No Mavlink Data from PX4 to OSD

I have recently upgraded from an APM2.0 to a Pixhawk PX4. Everything works fine
except i cannot get any Mavlink data into the Minimosd

My Setup:

Mission Planner v1.3.5 build 1.1.5260.33055
APMPlane FW v3.0.3
Pixhawk PX4 (3DR)
Minimosd 2.1 FW. Minimosd-Extra_Plane v2.2 (3DR Non-Clone)
NO 3DR RADIO USED

3691126308?profile=original

The Minimosd Boots up fine, says Booting, completes, then just sits there.
The Minimosd has both power jumpers soldered and is powered just from the PX4.

I have spent a couple of days on this now and tried all the setting i can find regarding the SR1 parameters,
but nothing works.
I have also tried using Minimosd v2.0 and even swapping the rx/tx wires.

Can anyone tell me if APMPlane + PX4 + MissionPlanner + Minimosd should work?
And how to get it to work

Regards

James

  • Ok - after many hours of playing around with MinimOSD and MinimOSD Extra versions and

    trying every conceivable combination/settings of the SR1 parameters

    I have been able to get Mavlink data from the Serial1 port to my PX4 and it works!

    My simple solution - downgrade APM Plane from v3.0.3 to v3.0.1

    I would seem to me that there is a major bug in v3.0.3

  • OSD Toggle Channel    ch 6  for example

    Rotation Switching    off

    CT Tool for MinimOSD Extra 2.4.0.1 Pre Release r788.zip CT Tool for MinimOSD Extra 2.4.0.1 Pre Release r788.zip, 479 KB

    • Ok i have used the 2.4.0.1 r788 CT and loaded up MinimOSD_2.4.0.1.mcm

      and MinimOSD-Extra_Plane_Pre-release_2.4_r719.hex (as it's the latest one i could find).

      The SR1 params look like this:

      3702497565?profile=original Serial 1 is also set to 57

      Iam now getting "No MAV DATA!"

      ?

    • Thanks

      I will give it a try when i get home and let you know

  • Minimosd software version?

    • Hi Xian06,

      I have tried Minimosd v2.0 and Minimosd-Extra_Plane v2.2
