DSP Tasks Failing Unless mini-dm is Run
-
When I read this a second time I noticed you told me to check the commander mode. I noticed that when I used the game pad the commander mode was put into POS_HOLD. When this happens it seems to cause the lag to build. If I command the vehicle to switch to STABILIZED or ACRO eventually the system seems to catch up and we see both uorb messages be shown realtime and we can see the HUD update mostly real time as well.
I am guessing the issue has more to do with being in a mode that requires position lock. Interestingly enough, when we have brought the aircraft to the field and booted it with clear view of the sky so that the GPS can get lock, we have seen the aircraft either not have the lag and link loss or have lag and link loss for a few seconds then go away.
You said that you thought mode AUTO_LOITER used too much CPU, do you happen to have any thoughts on which of the modules are using the CPU or where the problem might be originating?
@ejohnson01 Can you try bringing this commit into your build and see if it resolves the issue: https://github.com/modalai/px4-firmware/commit/f945d29064b4ab26617a3fb15fc770f5dcb993e9
