Hi all,
I'm working on imx6q with android 5.0.
We have met a problem with using desk clock alarm to wake up from sleep mode.
Sometimes it works fine, but sometimes it can't wake up,
espically when the alarm time is far from current time.
It seems like there are some problems in rescheduleKernelAlarmsLocked(AlarmManagerService.java).
We have tested this issue on boundary devices BD-SL-i.MX6.
It has the same problem.
Does any one know how to fix this issue?
Any advice or suggestions will be greatly appreciated!!
Thx
Yen
Hi Carlos,
I have tried the patch
but it failed
and showed error message as below

When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
Could you advise me how to apply the patch
Thx

Hi,
It seems the conflict of kernel version.
Can you tell me which standard GA release are you using?
Best regards!
Hi Carlos,
I have applied the patch file to the android 5.0 project successfully.
But it can't go into sleep mode now.
It just only close the screen, but when I touch the mouse, it will open the screen.
Is this the correct behavior?
Thx
Yen
Hi Yen,
Have you tested it on SABRE SD or SABRE AI boards?
Could you please provide the steps to reproduce it?
Best regards!
