First of All , i welcome all of you to this new forum.
I wish this forum will best serve the Pixhawk Cube users.
I am using Pixhawk 2.1 Cube from many years . For sure it is the best open source Autopilot available in the drone market.
But recently i purchase 10 of them and 6 of them are having issues.
Mainly , while PH2.1 is powered from usb cable, it starts to roll / pitch itself and i get this Error “Error pos vert variance”.
When i try to debug the Error source i came to know that IMU1 stops working i.e gyro/acc readings are paused.
When i reboot the PH2.1 i only get 1 IMU left.
Note: Before this i had a crash in-flight due to this error.
