hello, community

         I have met the error for many times atfer hours of playing video through video app. The error leads to two problems:

1    The kenrel crash may cause serious problem of out product in the furture, that is what we do not want see. 

2    The error make the video app recognise network as not working. But when I refresh the video app, it still can play network video. and I can ping an internet IP. So it means that the network work fine, but the video app recognise not

What cause this error happens or how to fix it ?  Any answer will be appriciated.

error log follows

Hi Jeff

such kind of error were on older releases due to arm/gpu bugs

(just for test one can try to disable GPU). Please try latest L4.1.x nxp bsps

were most of these errata were fixed

Hi, igor

Thanks for you answer, how to disable GPU. I have tried disable GPU(vivante driver) in kernel CONFIG, and then built kernel and burnt boot.img. But the board can not access android, just printed error log in the phase of init continuesly(like this kind error: init kill * pid, packed ***).

another question is that I am using imx6q android 4.4.2,  should I just replace kenrel with another version or replace the whole BSP with the  lastest version

thanks

Have downloaded KitKat4.4.2_1.0.0-upgrade-gpu-to-latest-4.6.9p13-Ver6.zip and tried to patch to my source code manually( can not use patch command ). I found the patch do not match my source code version. For example

patch :

source code: kernel_imx\drivers\mxc\gpu-viv\arch\XAQ2\hal\kernel\gc_hal_kernel_hardware.c

pastedImage_16.png

gckHARDWARE_InitializeHardware  precise position:      This function was just called one time this file

pastedImage_17.png

so I wish to get the whole complete files, not just patch files. where can I get that
