Questions about sync slavefifo application
I have a board with EZ-USB FX3 device(CYUSB3014) and FPGA, connected to a USB3.0 host.I use a cypress sync slavefifo firmwave which at the path of EZ-USB FX3 SDK\1.3\firmware\slavefifo_examples\slfifosync,configure GPIF II to work at 32bit,100MHz,io_cfg.isDQ32Bit is CyTrue,end point configure 16*1024,dma size is 16384.
when I use the Control Center to receive data from bulk in endpoint,it can receive 16384 byte data.But,I use streamerExample to receive data,packets per xfer select 8,xfers to uqeue select 8,it receive 21 frames successfully when failures is 75 frames.
what can i do to improve transfer speed?
