Hi,


After changing another batch of imx6q chip, we found android system cannot boot done, it always hang at:

......

I/Zygote  ( 2151): ...preloaded 379 resources in 1771ms.

I/Zygote  ( 2151): ...preloaded 31 resources in 9ms.

D/dalvikvm( 2151): GC_EXPLICIT freed 29K, 1% free 6467K/6531K, paused 2ms+2ms

D/dalvikvm( 2151): GC_EXPLICIT freed 10K, 2% free 6457K/6531K, paused 1ms+1ms

D/dalvikvm( 2151): GC_EXPLICIT freed <1K, 2% free 6457K/6531K, paused 2ms+2ms

I/dalvikvm( 2151): System server process 2225 has been created

I/Zygote  ( 2151): Accepting command socket connections

D/SystemClock( 2225): Setting time of day to sec=86400

W/SystemServer( 2225): System clock is before 1970; setting to 1970.

the batch number with this issue is:

MCIMX6Q6AVT10AC SBCF1315 KOREA YOCFSBU.

 

the following chip has no problem:

MCIMX6Q6AVT10AC SBAP1250 KOREA XXAPSBV.

 

[Update] We used RTC stub instead of SNVS for test, and found system can boot up, but run very slowly. It is almost certainly SNVS is going wrong.

 

Anybody have any ideas?

 

Thanks.
