> I think the problem is that the YCINSWP setting on your board. In 8 bit

> variable in the board setup file, read it and set in isif.c. Please send a

> your board. On DM365 evm board file you can set it to 1 so that it works
> fine for tvp5146 and adv7180. In isif.c you can read this variable and
> update the YCINSWP bit in CCDCFG. Are you planning to send a patch for this?
