Forum Post: RE: DM365 IPNC: ISIF driver problem for YUV Input

Hello RaviKiran,

I checked for pclock, sync signals and data lines.

Pclock gives me 24MHz, HD sync signal gives 15.63KHz and there is valid data on the data lines. In case of VD sync signals i am getting pulses. Frequency keeps changing like 2500 KHz - 3663 Hz- 500 Hz so on.  How do i proceed now?Are these okay?

I also want to add some points.

Major differences between OV9715 and OV7955 are as follows:

OV9715 :

     gives RAW output (not YUV) and has10 bit data line (isif input type is set to CSL_CCDC_IN_DATA_TYPE_RAW)
    8 bit register address

OV7955 :

    gives YUV output and has 8 bit data line  (isif input type is set to CSL_CCDC_IN_DATA_TYPE_YUV8)
    16 bit register address

We are replacing OV9715 sensor with OV7955 and everything else remains as that of Appro's.
