head-tracker suspend problem on omap4430 based custom board

Kaushal Gupta

Hi All,

I'm using head tracker driver for MPU9150 on omap4430 based custom board.

when board is going to suspend state, headtracker is not going into suspend state
b'cz current is same as it was previously.
Current reading in resume state=> 8.37mA
Current reading in suspend state=> 8.37mA (it should be around 0.25mA)
How can i make head tracker to go into suspend state.
Help me plz...

with regards

Hello,

Could anyone plz help me regarding the power reduction why its not happening. ?

See the logs..4666.suspend logs.txt

See the $ kernel/drivers/rtc/rtc-twl.c file. 1376.rtc-twl.c

See the MPU file $ kernel/drivers/staging/iio/imu/mpu/inv_mpu_core.c 2330.inv_mpu_core.c

I want MPU9150 to go in suspend state and current ll be arnd 0.25mA.

Any answer would be very appreciable..
