I'm using different board.
What board? I would think the architecture of the OMAP3 ISP would
not change, based on the board?
It's a custom board with omap3630. ISP is not changed.
When I disable OMAP2_VOUT from defconfig "CCD output" is /dev/video2.
I see, I have that option turned off.
But result is the same - yavta sleeps at VIDIOC_DQBUF ioctl
How are you configuring the TVP5150? In particular these settings at boot time:
static struct isp_v4l2_subdevs_group my_camera_subdevs[] = {
{
.subdevs = tvp5150_camera_subdevs,
.interface = ISP_INTERFACE_PARALLEL,
.bus = {
.parallel = {
.data_lane_shift = 0,
.clk_pol = 1,
.bt656 = 1,
.fldmode = 1,
}
},
},
{ },
};
This is how you tell the ISP to run in BT656 mode. Without it, it will run
using the HS/VS/FID signals (and also in my experience does not work properly)
According "media-ctl -p":

Should be /dev/video4...
Could you send your pipeline setup and full output of 'media-ctl -p'?
Pipeline setup is:
$ media-ctl -v -r -l '"tvp5150 3-005c":0->"OMAP3 ISP CCDC":0[1],
"OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
$ media-ctl -v --set-format '"tvp5150 3-005c":0 [UYVY2X8 720x525]'
$ media-ctl -v --set-format '"OMAP3 ISP CCDC":0 [UYVY2X8 720x525]'
$ media-ctl -v --set-format '"OMAP3 ISP CCDC":1 [UYVY2X8 720x525]'
media-ctl output (with /dev/video4):
$ media-ctl -p

Hi
I'm trying to run OMAP + TVP5151 in BT656 mode.
I'm using omap3isp-omap3isp-yuv (git.linuxtv.org/pinchartl/media.git).
Plus the following patches:
TVP5151:
https://github.com/ebutera/meta-igep/tree/testing-v2/recipes-kernel/linux/linux-3.0+3.1rc/tvp5150
The latest RFC patches for BT656 support:
Enrico Butera (2):
omap3isp: ispvideo: export isp_video_mbus_to_pix
omap3isp: ispccdc: configure CCDC registers and add BT656 support
Javier Martinez Canillas (1):
omap3isp: ccdc: Add interlaced field mode to platform data
I'm able to configure with media-ctl:
media-ctl -v -r -l '"tvp5150 3-005c":0->"OMAP3 ISP CCDC":0[1], "OMAP3
ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
media-ctl -v --set-format '"tvp5150 3-005c":0 [UYVY2X8 720x525]'
media-ctl -v --set-format '"OMAP3 ISP CCDC":0 [UYVY2X8 720x525]'
media-ctl -v --set-format '"OMAP3 ISP CCDC":1 [UYVY2X8 720x525]'
But
./yavta -f UYVY -s 720x525 -n 4 --capture=4 -F /dev/video4
sleeps after
...
Buffer 1 mapped at address 0x4021d000.

Buffer 2 mapped at address 0x402d6000.
length: 756000 offset: 2273280
Buffer 3 mapped at address 0x4038f000.
Anyone with the same issue??? This happens with every other v4l test app
I
used.
I can see data from TVP5151 but there are no interrupts in ISP.
Why are you using /dev/video4? The CCDC output is on /dev/video2
