Hi igorpadykov,

I do get unuserful information from similar issue your provided.

Running OS is android, so I can not change the kernel version.

I just want you provide us a fixed this issue way base on android 4.2.2.

Have any patch or fix method base on android 4.2.2(kernel 3.0.35)?

I saw many questions about similar vpu issues asked on nxp community, but look like has no satisfied answer.

Thanks.

igorpadykov — Wed, 20 Jul 2016 11:34:27 GMT

Hi echo

as stated on suggested link this issue is well known in

kernel 3.0.35 and there are no workarounds or solutions for it.

Experts suggest to move on latest kernels where it is fixed.

Hope you will find this info as userful.

Best regards

Re: vpu blocking timeout and then system crash.

echozeng — Thu, 21 Jul 2016 02:38:42 GMT

Hi igorpadykov,

According to your suggestion, can we only replace 3.0.35 kernel to latest kernel base on Android 4.2.2?

Or must we update newer Android OS(such as 5.0....) including latest kernel? How about your opinion?

Thanks.

Hello, Echo:

Because you are using one older release, recommend to consider to check whether the following patches are integrated:

- From log, it seems data corruption may happen in video playback case. So please consider to check whether all known ARM errata fixes are integrated.

- Please check whether DDR is stable enough.

- Please check whether ARM/SOC/PU voltage settings are aligned with latest datasheet.

- Please try to upgrade GPU version. GPU upgrade to latest p13 for JB4.2.2_1.1.0 release

You can also try the following tests to narrow down possible reasons:

- Disable all power saving technology. Disable CPU Frequency etc.

- Disable system to enter WAIT mode.

- Try to disable VPU clock off operation.
