Unable to handle kernel NULL pointer dereference at virtual address IMX6

alokkumar — Tue, 30 Apr 2013 13:46:08 GMT

Dear All,

I have been facing some issue with stability of iMX6 build provided by timesys. I am using boundary devices board.

I am decoding 1080P RTSP streaming 60 fps resolution is little scaled down.

Along with QT weather app and a ticker. I am seeing something crashes with in ~ 24 hours. Are there any ways where I can reduce the crashes.

VS1 created. in fmt[NV12] win(0,0-1920,1080:1920x1080) out win(485,0-1925,960:1440x960)

Alok, could you take a look to this thread and see if it is helpful:

Alok,

Did this answer fix your issue? I just had the same crash and had never seen it before today.

Thanks

Timothy,

I too saw a similar crash for the first time this morning on a kernel that I have been successfully using for a week, however the CPU I am using is the Armada 510.

Must be the full moon.

I have been using this kernel for a month at least. Now, I have seen this happen a few times in the past couple of days. Although, I did just change my design to boot from a initramfs ram disk instead. Not sure if that has something to do with it or not. It would be nice if I could confirm that the linked to patch does actually work. It seems that this also screws up my video decoding and need to reboot to recover.

I am posting my full output if someone from Freescale can look at this. Nitrogen6X board, BSP 1.1.1, 3.0.35 kernel.

Hi Timothy

I have met this problem too.

Do you have found some answer. ; )

Thanks

timothybean — Wed, 10 Jul 2013 12:59:22 GMT

alokkumar please change the post's status as unanswered.

timothybean1, have you dump a core crash and review it with gdb?

Re: Unable to handle kernel NULL pointer dereference at virtual address IMX6

timothybean — Tue, 20 Aug 2013 15:41:00 GMT

Working on it now... I also have Eric Nelson helping me as well. But the more eyes the better.
