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?
