Actually I have asked the xilinx expert on the statistics. With the PLB_TEMAC, we can also get a result like that, say 300Mbps for TCP. (From their numbers, the throughput is even higher.) Some remindings from my experience: Remember to enable everything in the hardware and software which can

Dear Ming, Thanks to your comments , Our tests now give the following results: ML403---PC : 410Mbits/s PC---ML403 : 210Mbits/s We have described the characteristics of our base system in previous posts here In additiona we have : 1- enabled the ppc caches 2- we have set BD_IN_BRAM in

I'm using the Denx linux-2.6-denx.git repository with a Katmai board. I want to boot off a disk (initialized w/ Debian 4.0). I've installed a Promise Ultra133 Tx2 IDE controller card in the PCI slot, and configured it in the kernel.I boot this same disk w/ IDE card on other 4xx

Dear Mohammad, ML403---PC : 410Mbits/s PC---ML403 : 210Mbits/s These results are interesting. In priciple, board to PC will be less than PC to board. And also you board to PC speed is quite fast. I never had that high before. :) We have described the characteristics of our base system in

I am building the Linux kernel target zImage.elf in PPC branch of Linux Kernel 2.6.16.11 and then converting it to zImage.bin using OBJCOPY so that i can flash it to my PPC based target using BDI. i am currently facing issues in booting this kernel using my own bootloader(i am not using u-boot).
