We've finally got our ML505 board booting PetaLinux 0.40-rc3 !! Things
generally seem to work. We're using the TeMac ethernet module. When
our other engineer had been testing his design with a raw Ethernet
connect, he said he was getting 400Mbit/second throughput (I don't
know what tools he was using to test this). |
With PL loading and running, though, we're only able to get about 13Mbit/second through the network!!
We've connected directly to a Quad Core machine running WinXP SP2, connecting with a short 1000Mbit crossover cable. The boards were able to connect at 1Gbit. However, when I attempt ftp transfers to/from the box, I'm getting 1.8Mbps into the board, and 13Mbps out of the board. What is going on here?? Is this because of the default tcp/ip stack? Our HW engineer saw another tcp/ip stack somewhere that he says claims to get over 100Mbps, but I'm hesitant to try to rip out the installed stack and link something else in. Is that really necessary?
