Hi,
I'm using OMAP35x-PSP-SDK-02.01.03.11 for OMAP3530 EVM. The Ethernet data transfer speed is too low. It uses LAN9220 chip from SMSC.
Please let me know if there is an updated driver available.

The latest Linux PSP (as of today) can be found at http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/psp/AM35x-OMAP35x-PSP-SDK/03_00/index_FDS.html however, I am not sure that you will see significant Ethernet improvement moving to this release, though it does have the latest driver version. Keep in mind if you are using other TI software (like the DVSDK) there may be dependencies on the PSP/kernel version, so updating may cause other issues. The benchmark Ethernet performance is given here for this release.
In addition to the benchmarks provided by Bernie, the Ethernet bandwidth on the EVM is limited by the LAN9220 chip, which has a minimum read/write cycle time of 165ns. Others have found greater bandwidth measurements (~90 Mb/s) using the Gumstix board which uses the LAN9221 chip, which has a minimum read/write cycle time of 45ns. (Refer to this site and this forum thread for reference.)
