Hello Uwe,
thank you for the hint. There was problem with insufficient memory.
dma_alloc_from_coherent is called several times and when I allocated
only 4MB, last call failed. When I passed 8MB to
dma_declare_coherent_memory, it works. Unfortunately I do not
understand why 4MB is not enough for

Dear Uwe,
could you please give me some advice once more? It seems I'm not able to
make mx2_camera working by myself.
I have tried dma memory allocation in my board file in several ways, but
nothing seems to work. I use Video capture example for v4l2 for testing.

Hello Uwe,
thank you for the answer again, but I'm still in troubles...
Here is the code from my mach-imx27ipcam.c regarding camera initialization
and DMESG messages I got. The initialization is almost the same as in
pcm037 as you adviced.

Dear all,
I'm playing with imx27ipcam reference design and I would like to use more
recent (or actual) kernel than the one in BSP (2.6.19). I had no problems
with running 2.6.39 version from mainline, and now I want to get some

Hi Uwe,
thank you for answer. You are right I give no memory to camera device in
mach-imx27ipcam.c. I have tried to do it in same way as it is in
mach-pcm037.c but no success. Here is my init function
static int __init mx27ipcam_camera_init(void) {
int dma, ret = -ENOMEM;
