I want to play two different video on two different framebuffer(LCD/LVDS) for a long time,

but I got kernel panic message like " mxc_vpu 2040000.vpu: Physical memory allocation error! ".

And I found a similar discussion

So I refer to the suggestion in above discussion everytime I finished playing video than try to perform "echo 1 >/proc/sys/vm/drop_caches"

It seems to improved ,it can play video longer,but still can get kernel panic in the end

Do you have solution for this issue?


Thank you.
