The message handling was not obeying action focused messages and high-rate messages properly before. With this change update rates track the desired rates closely. Critical high-rate messages such as ADS-B are queued additionally to guarantee that all received packets are being correctly forwarded.
When starting aiding using EV only and commencing GPS aiding later, this change means that the GPS origin is set to the local position 0,0 point rather than the current vehicle position. This avoids large changes in local position when GPs aiding starts.
Fuse external vision data using a relative position odometry method when GPS data is also being used and enable both GPOS and EV data to be fused on the same time step.
This can help "unbrick" AeroFC when a bad firmware is loaded
and it keeps rebooting or it spinning in some loop.
No need to request to stay in booloader as it will stay
in bootloader because the pin is set.
- change memory allocation from stack to a malloc'd buffer. This avoids
increasing the stack size. And since FTP is rarely used, the buffers
are only allocated upon use and freed after a time of 2s inactivity.
- adds PX4_ROOTFSDIR as root directory prefix. This does not change
anything on NuttX, but in SITL it will avoid enumerating the whole
disk tree when using QGC (which enumerates all files recursively).
The provided argument payload->offset is in range [0, num_file_entries-1],
but seekdir might use a completely different range. It is not defined
by the API spec. It is only useful in conjunction with telldir().
Moves calculation only required for mag heading fusion into the if (_control_status.flags.mag_hdg) branch
When using EV yaw, the observed yaw angle is calculated directly from the EV quaternions using derived expressions from references in code comments.
This can happen for example when a param type is changed from int32 to
float. The type check will then fail if the param is stored and the param
import will be aborted.
Now we just skip the entry and continue loading the rest.
