Dear sirs,
I connect DVP to FX3, and use the code of AN75779. It can run without any error, but video can not be preview with any player.
The format of DVP is bellow:
Outpur format | UYVY |
PCLK | 74.25M |
H SYNC | 22500Hz |
V SYNC | 30Hz |
PIC-WIDTH | 1650 |
H-active | 1280 |
V-active | 720 |
FX3 print and usb traffic receive are bellow:
cyfxuvcdscr.c change two positions,
The code of AN75779 is downloaded from:
https://china.cypress.com/documentation/application-notes/an75779-how-implement-image-sensor-interfa...
Everything seems going well, why the video can not be preview???
Thanks for any replay and suggestion.....

Hello,
Have you changed the glProbeCtrl and DMA buffer sizeas described in https://community.cypress.com/t5/Knowledge-Base-Articles/UVC-Troubleshooting-Guide-KBA226722/ta-p/25... ?
16380 is the DMA buffer size set in the firmware. Meanwhile, you need to rebuild the GPIF II project if you change the width of GPIF interface.
