Summary0001266: [Smart3][BTF] Black screen issue after wakeup
DescriptionHi Kerwin

I registered this issue with Jira first.
jira link is
https://jira.skbroadband.com/browse/BTFAML-689

FW : v15.524.10
Test method : Vod Test script (new_CH-VOD-SENIER-ZEM_Youtube_Sleep_aging_0402.sh)

STB entered sleep mode at 13:33:37 and wakup at 13:33:53.
The problem is that the screen has been continuously black screen since wakeup.

After this issue occurred, I unplugged and plugged in the HDMI cable, and the video output is working properly again.
(It looks like an issue related to HDMI.)

I don't see any special clues yet.
Please check the log.

Thank you
YK.Jung

Hi Mr. YK. Jung,

Do you have other log files ?
From logcat.log.0001, Android VM seems restart very frequently.
Android system may have problem more earlier.
You can see process ID of AndroidRuntime changing from log below

Hi Kerwin

The shutdown vm value is occurring when input key evnet occurs.
This is not an issue. please check attached file

This issue seems to occur as a whole, including VoC.
and it does not occur in FW on February 9th (usb_bfx-at100_V15.522.56) . It could be related to HDMI.

I also reported to Amlogic. we need to find a solution to this issue as soon as possible.

Thank you
YK.Jung
