Hello all,
I got the ECP5 VIP EVK that includes Cypress CYUSB3014 FX3 USB3.
The default firmware for the CYUSB3014 is pre-loaded and it works with the demo config of Latice.
I want to change the image resolution of the demo and I was able to do it for the FPGA side but not for the Cypress side.
I got the UVC_AN75779 project but I don't know how to change the frame size in it.
Does anyone has the source files of the ECP5 VIP Cypress demo? and how do I change the frame size?
Thanks,
Ofer.

Hi Ofer,
I understand that you just want to change the resolution from 720p to 1080p.
When you mentioned 1080p 32bit - you meant that FPGA is giving the image data in 32 bit parallel interface while the pixel depth is still 2 bytes/pixel. Am I correct? If yes, your maximum frame size would be 1920*1080*2bytes = 0x3F4800 (But in frame descriptor and in probe control structure you mentioned it as 0x7C8100. Can you please clarify?)
You can also refer to Points 2, 3, 4, 5 and 11 of the UVC Troubleshooting Guide
