Android Lollipop Suspend and resume issue

[deepanrajanbara]

Hi,

We are developing Android lollipop based on NXP provided source code, we are implementing power management in android lollipop.when implemented  it was found that the device is resuming itself and going to suspend again.

We even referred to this link

https://community.nxp.com/docs/DOC-93616 

But they do not provide information related to this this type of information.Can any one please help in providing a solution to the issue which we are facing.Because of the this sudden resume and suspend there is a huge power spike which might cause a power related problems.

Thank you,

What you mean go to suspend again? 

Is it a screen off after 1min? (there is a setting in Android to switch off the screen if no action after 1 min) 

There is a bus frequency driver was enabled by default. If you want to enable or disable it, perform the following command in the console:
Disable:
$ echo 0 > /sys/bus/platform/drivers/imx6_busfreq/busfreq.x/enable
Enable:
$ echo 1 > /sys/bus/platform/drivers/imx6_busfreq/busfreq.x/enable

The LCD will be in off state only but when i connect the debug port and check my debug prints.i am able to see resume and suspend which is happening frequently.We even tested  on NXP provided binaries and even in the same issue persist.

Thank you,
