I'm using different board.
What board? I would think the architecture of the OMAP3 ISP would
not change, based on the board?
According "media-ctl -p":
- entity 5: OMAP3 ISP CCDC (3 pads, 9 links)
type V4L2 subdev subtype Unknown
device node name /dev/v4l-subdev2
pad0: Input [UYVY2X8 720x525]
<- 'OMAP3 ISP CCP2':pad1 []
<- 'OMAP3 ISP CSI2a':pad1 []
<- 'tvp5150 3-005c':pad0 [ACTIVE]
pad1: Output [UYVY2X8 720x525]
-> 'OMAP3 ISP CCDC output':pad0 [ACTIVE]
-> 'OMAP3 ISP resizer':pad0 []
pad2: Output [UYVY2X8 720x524]
-> 'OMAP3 ISP preview':pad0 []
-> 'OMAP3 ISP AEWB':pad0 [IMMUTABLE,ACTIVE]
-> 'OMAP3 ISP AF':pad0 [IMMUTABLE,ACTIVE]
-> 'OMAP3 ISP histogram':pad0 [IMMUTABLE,ACTIVE]
- entity 6: OMAP3 ISP CCDC output (1 pad, 1 link)
type Node subtype V4L
device node name /dev/video4
pad0: Input
<- 'OMAP3 ISP CCDC':pad1 [ACTIVE]
Should be /dev/video4...
Could you send your pipeline setup and full output of '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.
length: 756000 offset: 1515520
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
