USB 2.0 on the FX3 Super Speed Explorer Kit SlaveFIFOSync code
I am working with a FX3 Super Speed Explorer Kit in Linux and I am using the SlaveFIFOSync in APP note AN65974. I was able to get the USB 3 running at about 2Gbps, but USB 2.0 is only 30Mbps (bits NOT bytes). I notice that the burst length in the code is not 16 for the "case CY_U3P_HIGH_SPEED:", but rather it is set to 1. I tried to change it to 16, 8, 4, and 2 and they all will not allow the image to load on the board. I don't know if I am even looking in the right place to speed up the USB 2.0, but I figured it was a good place to start. I need to get the USB 2.0 to run at the ~480Mbps rate. Does anyone have any experience with the USB 2.0 side of the SlaveFIFOSync code?
