I am using micropix,
When i enabled all the options for the CX-OF i noticed i started having problems connecting,
I would get hangs on the “Got param STAT_RUNTIME” screen.
When i connected immediately after boot it was ok.
When I changed mod to “flowhold” i had the “no such mod” screen (also on 3.6.6).
Now with the fmuv3 version on arming i get:
PreArm: Waiting for Nav Checks
On boot i also saw NavEKF2: allocation failed
After a few minutes while connected i stop getting updates to the HUD and when I disconnect i can’t connect back without a reboot.
Is it memory issues? (I also have these problems with chibiOS)
Thanks. I don’t think any of the dev team has one of those, so it’s untested, and it’s not obvious what the manufacturer has changed from spec on the board.
The first thing I’d check is the power supply. Does the issue occur when on battery, or just USB?
The “NavEKF2: allocation failed” means that the EKF hasn’t been able to allocate enough memory. This is quite severe issue actually and surprising because most Pixhawk-family boards have more than enough memory available. Perhaps a ton of features and/or more than two EKFs have been enabled. If you have a parameter list or preferably a dataflash log we can have a look.
