Hi,
I am porting a ov3640 cmos camera driver to dm365 platform. The camera output general YUV422 data through CIN0~CIN7 data lines, all the signals including HD,VD,PCLK are OK.
The matter is, when I started the transfer and captured a frame of image, all the data received are only 0, even though I pulled all the data lines high by a CPLD(should be read out 0xff of all the bytes!)( the CPLD interfaced between cmos and cpu with VPFE signals), it seems that dm365 hasn't read data from data lines? I have also tried to change the value of CCDCFG.YCINSWP to make sure it has read the right data lines, but there was no effect.
Following is the setting of some registers in ISIF module. Please give me some hints, thanks.
