CMA Memory issue with 13mp still capture in imx6

Hi,

I am facing issues while taking still continuously in imx6 Quad. The resolution of the captured image is 13MP. I am noticing this issue in Android Marshmallow and Nougat releases. I am taking stills continuously using the default camera application. After a certain time dma_alloc_coherent call fails with -EBUSY. 

I have tried changing the cma value in bootargs

By default it was 384M. I have also tried 448M

Hi Ashwanth

 Try to change the cma value on your uboot:

cma=256M androidboot.selinux=disabled

Hi, I have tried changing the cma values. It just prolongs the inevitable.
