Android JB not wakeup

Hi all, I am now porting the Android JB to our customize board using IMX6Q, but it's stop here:

snvs_rtc snvs_rtc.0: setting system clock to 1970-01-01 00:00:01 UTC (1)

Freeing init memory: 240K

init: no such service 'bootanim'

ERROR: v4l2 capture: slave not found!

I have try with uart or rtc wakeup, but the it still sleep:

echo enabled > /sys/devices/platform/imx-uart.2/tty/ttymxc2/power/wakeup

echo +3 > /sys/class/rtc/rtc0/wakealarm

So, how can I wakeup my Android JB?

Thanks

Hi chen,

The board is designed by customs, and which BSP are you use? Would you please attach the whole log file？

Best Regards

Dan

Hi Dan,

Thanks for your reply.

Sorry about my late reply. I just used BSP from Freescale with some modifications to test. I attached the log file

Best regards.

Hi chen,

I wonder if your problem have solved. If not, which version android BSP are you using? And what have you modified? From the information you gave, it's hard to detect where the problem is?

Best Regards

Dan

Hi, chen

Can you measure the PMIC_STBY_REQ pin on the board, better to monitor it from RUN mode->Sleep->wakeup, the level should be low->high->low. If it is high when it is not waking up, that means system still in sleep mode, the wakeup source on your board did NOT work. Please measure this signal first.
