tutorial4_es20 freezed after about 46 hours

[charleshuang]

Hello,

I perform following commands on Freescale SabreSD evaluation board with L3.0.35_4.0.0_130424_images_MX6.tar.gz

     $ cd /opt/viv_samples/vdk

     $ tutorial4_es20&

After about 46 hours, the rolling ball is freezed, but debug console is still workable, so I kill the process,

and perform tutorial4_es20& again, the screen turns black only, no rolling ball shows up.

Does anyone can tell me what is happened and how to avoid this phenomenon ?

Hi charles

this may be caused by memory management problems in 3.0.35 kernel

(memory leak), it is not solved in this kernel.

Recommend going to 3.10.17 if it is possible.

Long running vpu task with memory leak bug on imx6

Hi,

I am also seeing the same issue of "freezing" application window on the target's display with 3.10.17_1.0.2.

I tried "09_VIV_direct_texture" and it freezes after approximately 7 hour of running. However platform is responsive and can again launch the same application if I restart the xserver.

Do you have any information/update/fix about this issue? Where can I find more information on this issue? Do you know why the xserver gets killed when I kill the application?

Regards,

Vikash

Hi chip,

Using Yocto 3.10.31_1.1.0_beta to test tutorial4_es20 again, the rolling ball is still frozen after 94 hours,

how can I do ?

Hello Charles,

as we discussed last time in the meeting, please don't use rolling ball(tutorial4_es20) for the test, there is something wrong in this application, the frozen is expected.

Please use "gear" for the long-run test.
