Other Parts Discussed in Thread: AM62P, SK-AM62P-LP
Tool/software:
Now I evaluate a SK-AM62A-LP board. I don't have a LCD screen , so I connect a extern screen through HDMI. On linux ,it works fine. But when I change to Android system, the display turn off and then turn on per minute.
The image I used is AM62Px_userdebug_10.01.00_emmc.tgz . I have tow monitor , the problem is the same. When the screen blink , there is log
Display device changed render timings: "Built-in Screen", renderFrameRate=60.0, presentationDeadlineNanos=16666667, appVsyncOffsetNanos=1000000
bellow is the total log
