Hello sir ,

Actually i am interfacing ov7670 camera module with fx3

board,and for functioning ov7670 it requires external clock in mhz.so, i am

complexgpio.But ,the problem is only pwm part is working and a pulse of mhz

is generated on fx3 pin.but in device manager uvc is not appearing.. Below i

Hello Manisha,

Upon using the descriptor file and the uvc related files that you have shared, I am able to find the device enumerating as a UVC camera. Kindly, recheck.

Best regards,

Hello Manisha,

Please share the descriptor file also. Also, mention if you have made changes to the firmware to suit the image sensor that you are using.

Best regards,
