Hi I am noah
I am working with FX3 evaluation board for UVC application
My latest work was 1920x1080 30Hz UVC yuv2 video, It works well
But I need 1920x1080 60Hz UVC application
I modified from example application (an75779)
I changed 32-bit Data bus, resolution, frame rate, buffer count in source code
in GPIF design, data_count, address_count set to 4091
But, video is broken
I don't know what I miss
Please check my attached project
I am using vitualDub, and it recognize well 1920x1080 60hz video but screen is broken
my question is that fx3 works well for 1920x1080 60hz uvc??

Hi Noah,
Could you let us know the value of PCLK?
Also enable debug prints for the firmware and kindly share the debug prints with us.
Best Regards,

Hi AliAsgar
PCLK is 74.25Mhz
horizontal sync total 1100 clock, vertical sync total 1125 clock
1125 x 1100 x 60Hz x (1/74.25Mhz) = 1 sec, is it right?
If you need to see debug print log, I will prepare log file, It need more time
Do not have any problem in my source code?
thank you for your fast response
