Crash of android on imx6 board when playing with GUI.

oussama — Tue, 20 Jan 2015 18:51:23 GMT

Whenever I play with android GUI, no video, just navigate through settings, the android crash/hang after few seconds.

I'm using android kitkat with kernel based on the fsl kernel 3.10.17 with custom board similar to the sabresd one.

Here's some info/error from logcat about SurfaceFlinger:

I/SurfaceFlinger( 144): renderer : Vivante GC2000

W/SurfaceFlinger( 144): Ignoring duplicate VSYNC event from HWC (t=0)

And there is more than 14000 occurance of the last message!

What's is the cause of those 14000 message of "Ignoring duplicate VSYNC event from HWC (t=0)"?

Is there some way to check if the android graphic stack can function properly?

Sometimes there some messages like this

Hi oussama

had you customized board Device Configuration Data (DCD)

(mx6q.cfg) with new DDR settings running DDR test ?

i.MX6 DDR Stress Test Tool V1.0.3

Hi oussama

as far as I know kk4.4.3 (kernel 3.10.17) is not released yet and it is beta,

what is about IMX6_KK442_100_ANDROID_SOURCE_BSP

or just linux - is it also crashing ?

Best regards

Hi Igor,

Linux itself does not crash. only android.

Hi oussama

suggest to use IMX6_KK442_100_ANDROID_SOURCE_BSP

soon kk4.4.3 will be released so one can try it later.

Hi Igor,

The GUI is not smooth. for example when I move the mouse cursor, the refresh is sometime delayed although the cpu load is very low.
