Hi Paul, Thanks for the help. On 10/6/2012 12:23 AM, Paul Zimmerman wrote:
If the host controller in your PC is not connected thru a PCIe bridge with multiple lanes, the connection will not be fast enough to support that high of a transfer rate. And maybe on your eval board the host controller has a direct connection to the memory controller? Just a guess.
Actually in both the case I am using single lane PCIe interface. I connect same PCIetoUSB3.0 card (tusb7340evm) with PC as well as with eval board .
A faster CPU doesn't help if the hardware cannot keep up.
Yes.
One thing you could do is try with a higher value for '-g' on the test command line. That will make the usbtest driver use more scatter- gather entries when it does the DMA. Perhaps that will help.
