I don't think the driver can use DMA. If you need more speed than 26 MBits/s, you might have to go through the USB interface. We hit a similar issue of wanting to get full 100 mbit speed of the ethernet and realizing that the interface to the card is just bit-banging and won't support much speed. It's really there just for development use.
We examined using a usb ethernet card to get more more bandwidth, but we didn't go through with that project. good luck Chris On Fri, Aug 8, 2008 at 1:44 AM, Kumar Bala <[EMAIL PROTECTED]> wrote: > Hi, > We are trying to improve the ethernet performance on the DM355 EVM.
