Hi,

Is one sensor working correctly with FX3?

Have you referred to section 9 of the application note you mentioned?

Could you confirm if both the sensors are transmitting data to FX3?

When one sensor works, it can work with FX3, I have made the descriptor changes according to section 9, two sensors have data to FX3, and through the Bus Hound software test, there is data transmitted to the host computer, however, after a while it will be Stuck, the VSYNC, HREF, PCLK signals of the two sensors are synchronized normally

Hi,

Could you send different predefined patterns from each of the sensors, (For ex, 0xAA from sensor 1 and 0xBB from sensor 2) and then take the wireshark traces at the host PC to share the same with us.

Also please enable the debug prints and share the debug logs with us.

Which host application is used to view the data?

I use I2C for data transmission at the same time, and AMCAP for image acquisition

Hi,

I can see that there is video data coming from FX3 to the host.

Could you tell me if the individual sensor's resolution is 640*480, meaning total resolution from two sensor would be 2*640*480.

I see that there is a partial packet of 6436 in the bushound, is the same amount of partial packet seen always?

Could you also send us the descriptor file used in your application?

Best Regards,
AliAsgar
