Issue: Aspirin v2.2 HMC data freezes after power-on
Description: After powering the IMU board, sometimes HMC58xx compass output
freezes. I have checked it by using IMU_MAG_RAW on telemetry/raw sensors
When the issue occurs I have also checked the other sensors on the board, it
seems IMU_ACCEL_RAW and IMU_GYRO_RAW are updated correctly.
*issue* I'm now on v5.4.The error counter of telemetry for IMU_MAG_RAW is
not increasing, it performs like this in the MESSAGE :
After checking the HMC datasheet, I am suspicious about lock state of SR1
bit of HMC status register. Datasheet states that "When this bit is set, the
six data output registers are locked and any new data will not be placed".
I am still digging and try to solve this problem but I wonder that is the
issue board specific or has someone face an issue like that?
