The Gpif examples need to have an external device connected to the GPIF interface. However, you can try the GpiftoUsb example project, which samples the unconnected gpif data lines and transfers it to the USB. You do not need to connect any external device to run this example.
Also, we recommend you not to revert to 1.3.1 SDk as the bugs with it are not supported and have been rectified in 1.3.3
GPIFtoUSB example works fine with my Cypress Ez-USB exploler kit.
However, GPIF II interfaces with external Clock and other GPIF signals does not work when required signals are connected.(UVC and Slave Fİfo)
Are there any solutions for this issue? For UVC, I made all connections in AN75779 and I have no frame data in VirtualDub although Windows 8.1 sees device as usb video device.
Thank you for attention.
