Hi Lei,

Are you using the firmware that has been provided with the application note AN75779?

http://www.cypress.com/?rID=62824

What Image sensor are you using?

Please check the configuration of Image sensor registers.

Also please let me know what exactly is the behavior of your system.

Thanks,

Sai Krishna.

Hi Sai,

Yes, that is UVC sample code AN75779,

I am sure that sensor setting is correct.

and also I checked sensor output data and

FV,LV and PCLK which is 38M, I used a image sensor

DVP interface connect to GPIF 2,( 8 bit data and

1280x720 with 15fps)

the issue is that I cannot see correct data on

USB bus, but I can see 12 byte header or footer?

"0C8E" or "0C8F", it seems firmware cannot

capture frame header? That FV can cause

an interrupt for capture frame start? Do I need set

Interrupt ? Please help this. Thanks a lot!

thanks a lot!
