optical flow position mode - "no local position" error

[ambikaverma]

Hi

Im trying to test optical flow on intel aero. My setup is as follows -

px4 - ver 1.8.0
bios - latest yocto image.
indoors, when the uav is stationary.

I start optical flow manually using ./aero-optical-flow command to see if the features/texture is good enough. Looks like its good enough since I don't get any desired number of feature prompts. Also the quality is on 180-200 range.

And on arming the flight mode does change to position hold.
But, instantly I get "no local position" error. I can share screenshots of above if required.

Any suggestions on the cause for this?
Thanks!

Any fixes of above issue?

as per here-
intel-aero/meta-intel-aero#376

I would need to debug px4. How do I go about doing that?
I tested altitude hold and the flight went fine, but optical flow position hold is still going into failsafe of no local position.

@priseborough @LorenzMeier any inputs will be hepful. Thanks!
