I download the stack (TUSB6020 USB OTG Driver V1.00.01 DSP/BIOS),build and run it in my DM6437evm board.TUSB6020 connected as a “B” device.PC found it as a 2 Meg RAM drive.I tested it, the max read rate is only 8MB/S,and max write rate is 3MB/s.The tusb6020 connect with a 4 tx pin and 4 rx pin, 99 MHZ VLYNQ clock,dsp run in 540MHZ. I noticed the readme file in driver stack :
Know Issues:
- DMA is not functional.
- Messaging needed for USB OTG Compliance Testing prints to the JTAG interface not the COM port.
- Single Step Set Feature for USB HSET Testing needs to be reconfigured.
DMA is not functional in the driver stack?But i need the throughput up to 160Mbps.What should I do next? Is there anyone that has had tested the tusb6020 actual throughput in DM6437 board?
