Are you using Cypress OV5640 example project?
Can you please let us know the DMA buffer size and count of your video channel?
Are you seeing COMMIT buffer failure error (Error 71) for the failing resolution?
I using Cypress CxUvcOV5640 example project (EZ USB Suite 1.3.4) just a moment ago. But the camera still not displaying properly.
The lower part is dynamic (up and down)
Where do I get DMA buffer size?
What is count of video channel?
I am not seeing any error message when I run my OpenCV video capture program.
Thanks for your help.
Please continue debugging with the example project without any modification.
With the example project, are you not seeing video with any of the four resolutions supported in USB 3.0 operation?
5Mp, 1080p, 720p and VGA?
Can you please cross check the schematic of your board with Denebola reference deisgn (http://www.cypress.com/documentation/development-kitsboards/denebola-usb-30-uvc-reference-design-kit-rdk ) ?
Please confirm whether you have Denebola kit with you?
Do you have feasibility to get the UART debugprints in your board?
