Hi,
I am having IMX6 dual lite sabreSD board. I amtrying to capture a still image with resolution 4192 * 3104 but every time I get page allocation error from ipu_csi_enc.c .
Below is the error whic i get:
page allocation failure: order:13, mode:0xd1

ERROR:IPU CSI v4l2 capture: Allocate dummy frame failed.
ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0
VIDIOC_DQBUF failed.
I have checked IMX6 application processor reference manual in which it is clearly stated that maximum frame size supported by IPU is 8192 * 4096 pixels, so my requirement is far below than the maximum. So I doubt if there is some limitation in any of the driver related to memory alocation .
Kindly please provide some inputs regarding this.
