I am using DM368 TI board with LI-5M02 leopard image sensor board...

using this to test the video loop back but i can't get image output..

i have attached my video image and VPFE and VPBE register setting s here for your

reference...please help me

1.CMOS sensor output 12 bit Bayer pattern raw image

What SW do you use to capture and display the video? Did you get it from TI or from Leopard? Looks like this is a color patten related issue.

hi..

Am currently developing the firmware to initialize the cmos and display the image to TV

in component video mode.. am not using the Linux OS or anyother source..

just following the video_loop_ back sample test code

we are going to use only firmware part to develop the video image

not using Linux OS.. So please help us

for Register Setup for ISIP and IPIPE IPIPEIF

for Bayer RGB cmos camer sensor

Thankyou!!

Like I mentioned earlier. This looks like a color pattern issue. Can you please try changing the SRC_COL register in IPIPE to see if it makes a difference.

Natarajan,

is this problem has been resolved ? As the poset is marked as verified i assume it is resolved.

If not i found some registers which doesn't seems to correct.

ISIF_MODESET =0x1000;

MODESET -> INPMOD looks to be 1 it means your input id YcbCr-16 bit data but you have mentioned it Ray Bayer 12 bit data.

Also for color shifting you can use different values of following registers. Like setting SPH to 1 your input data can be shifted 1 posstion.

ISIF_SPH = 0x0000;

ISIF_SLV0 = 0x0000;

ISIF_SLV1 = 0x0000;

Thanks
