I connected MPU6050 and AKM8963 to dragonboard. I used drivers that comes with the kernel source. I changed dtsi files as i needed. Then i was able to enable sensors. The sensors work well, when i try them seperately.
But compass does not work. I use physics toolbox suite app for testing the sensors. I see below error from debug port when i use compass or linear accelerometer.
First “sensors MPU6050-gyro: Invalid value of delay, delay=5” error comes and then “akm8963 0-000c: AKECS_Set_CNTL: device is busy.” and “akm8963 0-000c: Failed to set mode.” errors come.
I did a lot of hard work but i couldn’t solve this problem. Are there any one to help me to solve the problem.
