imx6q android system reboot issue on Android 4.3 after several seconds

pfsang — Wed, 25 Jun 2014 04:22:04 GMT

hi, ALL

i encountered a problem about system reboot after about 20s.(i set android sleep time to 30min)

my cpu (imx6q) works at 1Ghz.

when i operate android (like play video, touch the panel), the system do not reboot automatically.

but when i do nothing , the system will reboot after about 20s . (i have tested several times).

i also tried it on imx6DL, it has not the phenomenon .

i have attached the log.

by the way , i haven't ported pmic into the system. does it cause the reboot?

do anyone give me suggest about how to debug it or what's the root cause?

Thanks

peter

Hi,

Can you provide logcat detail?

And also check "developer options --> stay awake" and "Display --> sleep time"

Does it reboot even if you stop autoboot?, or is it only rebooting when you let android start?

Is it a custom board you have? Have you ported the PMIC?, are you still having this issue?
