I noticed that the encode data sheet says that the input width and height must
be multiples of 16. In the case of 1920x1080 the 1080 is not a multiple of 16.
However, I have seen sample code where 8 is added to the height so that the

Andrea,
I haven't tried this myself, but would it be possible to use the memmap command
line parameter to reserve a chunk of memory that the kernel will not try to
manage. I think this will bypass the MMU as I have seen that you can limit the
kernel to using less memory and then use the DDR

Did you develop the module TVP5150 from scratch or borrowed from open source?
Also dump the ccdc registers and make sure the settings are as per my email
below. Let me know once you confirm the ccdc settings are correct.

Andrea,
If you are using BT656, then your CCDC register settings are not right. They
have value 0. I am using TVP5146 input. Are you using sensor input?
Here is a sample from my setup... Probably this helps...

Pay attention to MODESET, REC656IF and
0 0003
This is what I use to set up 656:
/*
* setup656sync
*/
/* This function will configure TVP5150 output data formatting */
static int setup656sync(tvp5150_params * tvp5150params)
{
int output1, output2, output4;
int ret = 0;
