Hi, I'm trying to port Guennadi's patches (http://download.open-technology.de/BeagleBoard_xM-MT9P031/) to last mainline kernel 2.6.39-rc.
I've managed to compile and configure the video interface using the suggested commands: root@beagleboard:~# ./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] root@beagleboard:~# ./media-ctl -f '"mt9p031 2-0048":0[SGRBG8 320x240], "OMAP3 ISP CCDC":1[SGRBG8 320x240]' Setting up forma[ 75.031677] mt9p031_set_format(320x240 : 1) t SGRBG8 320x240 on pad mt9p031 2-0048/0 Format set: SGRBG8 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 However, when I try to capture some frames using yavta I get the following: root@beagleboard:~# ./yavta -f SGRBG8 -s 320x240 -n 4 --capture=10 --skip 3 -F `./media-ctl -e "OMAP3 ISP CCDC output"` Device /dev/video2 opened: OMAP3 ISP CCDC output (media).

And the image files I get are filled with 5555 instead of useful data. Does anybody know whether those iommu errors are harmless? Do I need to enable CAM mux inside arch/arm/mach-omap2/board-omap3beagle.c which are currently disabled using an ifdef? Thank you. -- Javier Martin Vista Silicon S.L.
