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 suggestions for above issue? Im still getting no local position error.
ekf_aid_mask = 2
ekf_hgt_mode = range sensor

optical flow quality is good 180-200 and I'm able to switch to position hold mode, but instantly goes into failsafe for "no local position"

Looks very similar to #372
as said in that issue, try to switch to altitude mode to make sure everything lidar is working other than that you will have to debug PX4.

Do you have a laser connected?
