I see that some things are working and some are not.

That can be caused by at least two things:
 - version mismatch between FC firmware and OSD firmware (they must match perfectly)
 - telemetry is disabled for those objects for some reason

I notice that compass is spinning.  That is strange too.

It strikes me that there is an assumption I made and that is that the GPS is connected to the FC, not the OSD.

Instead, maybe you have the GPS connected to the OSD.  In that case, it could be that you simply don't have any data successfully coming from the FC.  You must configure the FC port that the OSD is connected to (MainPort, FlexiPort) for telemetry, and at the same baud rate as the OSD is expecting to read it.  Also, a common problem is that for serial links like that, the FC Tx pin must connect to the OSD Rx pin (and Rx to Tx).

Thanks TheOtherCliff.
Here is what I have.

1. GPS DJI Connected to FC (Revolution)
2. OSD Connected to MainPort setup as Telemetry 57600
3. Firmware LP_All_From_Revo261017+AnalogRSSI_MicroKvteam_pin3.hex as of https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/7274504/MinOPOSD+setup
4. Flight Controller firmware per (r711) release of GCS https://forum.librepilot.org/index.php?topic=4263.0
5 OSD Set as https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/7274504/MinOPOSD+setup

Please let me know if you need more information.

Regards

P.S. how do I enable Telemetry for the Objects?

It looks like you are running 'next' on the FC.  I don't thing that OSD firmware version is equal to next 711.  That is your problem.

I don't know enough about OSD to know if that micro kv team pin3 is what you need.  That is also a possible issue.  I am guessing someone pointed you to the correct OSD firmware.

If you have the FC port set for telemetry on the Hardware page, you are probably OK for testing.  You can selectively enable/disable / adjust timing for telemetry objects on the System page, but the default should work.  You may want to increase the frequency of some objects, but that is not your problem.

An easy test would be to flash 16.09 on the FC and set up for OSD and see if it works.

TheOtherClift,

I was able to fix the issue. I upload the MWOSD, and set the port to MSP, then I was able to see movement.

See video.



Thank you for your help as always.
