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??

thank you

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.

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

Hi Noah,

1. Please find the attached firmware project, which is modified to print the frame size.
2. Could you check if the same issue is seen on different Host Applications and/or different Host PCs?

Best Regards.
