The hexacopter I fly has completed many missions using PX4 v1.8.2 and earlier. After updating it to 1.9.2 it has experienced problems. The flight in this log looses x, y, and z position set-points just before the failure. Why is this happening? Is the Pixhawk 1 unable to keep up with v1.9.2??? What could be happening to stop the mission? This type of failure occurred in 4 out of 5 missions.
In addition, could use some help understanding the following errors:
- [mc_pos_control] Position-Control-Setpoint-Update-Failed
- [load_mon] gps low on stack (260 bytes left)
- [gps] ubx msg: txbuf alloc
Thanks for any help that’s offered.
