Hello,
I'm puzzled to know if the pxa_camera driver can manage a data depth
different from 8 bits.
I'm currently trying to add a camera interface support to my PXA270
based board with an adv7180 as soc camera device.
For the adv7180 I defined:
static const struct soc_camera_data_format adv7180_colour_formats[] =
{
{
.name = "Planar YUV422 16 bit",
.depth = 16,
.fourcc = V4L2_PIX_FMT_YUV422P,
.colorspace = V4L2_COLORSPACE_JPEG,
}
};
but this is rejected by the pxa_camera driver buswidth_supported().
On the other hands if I set .depth = 8 in above struct I get the
following:
debian:~# gst-launch v4l2src ! video/x-raw-yuv,width=320,height=240 !
filesink location=/tmp/video.raw

That is the pax_camera device returns 8bits per pixel instead of 16...
Can you please help me in finding what's wrong? :'(
Thanks in advance,
Rodolfo
