Hi,

Have upgraded the driver to Javier's latest RFC driver.
Still having problems viewing output.

Setting up with:
# media-ctl -r -l '"mt9p031 2-0048":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
Resetting all links to inactive
Setting up link 16:0 -> 5:0 [1]
Setting up link 5:1 -> 6:0 [1]

# media-ctl -f '"mt9p031 2-0048":0[SGRBG12 320x240], "OMAP3 ISP CCDC":0[SGRBG8 320x240], "OMAP3 ISP CCDC":1[SGRBG8 320x240]'
Setting up format SGRBG12 320x240 on pad mt9p031 2-0048/0
Format set: SGRB
Setting up format SGRBG12 320x240 on pad OMAP3 ISP CCDC/0
Format set: SGRBG12 320x240
Setting up format SGRBG8 320x240 on pad OMAP3 ISP CCDC/0
Format set: SGRBG8 320x240
Setting up format SGRBG8 320x240 on pad OMAP3 ISP CCDC/1
Format set: SGRBG8 320x240

Then:
# yavta -f SGRBG8 -s 320x240 -n 4 --capture=100 -F /dev/video2
Device /dev/video2 opened.
Device `OMAP3 ISP CCDC output' on `media' is a video capture device.
Video format set: width: 320 height: 240 buffer size: 76800
Video format: GRBG (47425247) 320x240
4 buffers requested.
length: 76800 offset: 0
Buffer 0 mapped at address 0x4006c000.
length: 76800 offset: 77824
Buffer 1 mapped at address 0x40222000.
length: 76800 offset: 155648
Buffer 2 mapped at address 0x4025e000.
length: 76800 offset: 233472
Buffer 3 mapped at address 0x402f0000.

After this it hangs and will exit on 'ctrl c':
omap3isp omap3isp: CCDC stop timeout!

Any ideas what is causing this problem?

No idea,
it works for me. Note you have to apply RFC + PATCH v2 2/2. Please,
double check.

Also, if you have problems with last RFC patch you should answer RFC
mail. Not this one.

Thank you.
