Hello,

Please check the driver version, host application and host controller in both windows 10 and windows 7. The snapshot is working properly in windows 7, that means the FX2LP device is receiving data properly from the image sensor but the host is not capturing the data properly.

you can refer to Interfacing FX2LP™ with Image Sensor – KBA95736 for an example host application implementation.

Hello,

Can you please let me know which FX2LP project are you using as a reference for your design.

Please refer to the Aptina Cypress FX2LP Reference design firmware for implementation.

Hello,

Can you please let me know if the device is enumerating properly and is bound to the proper driver in device manager. You can compare this in both windows 7 and windows 10.

Hello,

Can you please check the speed of the enumerated device in windows 10, if it has enumerated as a full speed or a high speed device?

You can use the USBview or USBTreeView application to check the same.

I downloaded you project and it built successfully with 0 errors. Please check if C51.exe is present in the path: C:\Keil_v5\C51\BIN\ on you system.

Try reinstalling Keil uv 5.
