Gb Ethernet on xilinx gemac IP
Hi Xavier, Just wrapped up efforts to experiment with hard TEMAC support in 2.4 kernel ( previev kit from Montavista ). DENX 2.4 distro should not be different. Here are my experience with ML403 board: Configure kernel for only eth driver offered for ML300 / ML403 ( soft EMAC - 10/100Mb on-chip eth ). After updating kernel tree with the BSP using xilinx patch script for ML403, hard TEMAC driver will end up in /drivers/net/xilinx_gige ( supported soft MAC driver ends up in /drivers/net/xilinx_enet ). >From here 2 options: a) rename xilinx_gige folder to xilinx_enet and build kernel b) modify config.in script for kernel network configuration and makefile for building net driver by addidng new GIGE option >From my undersanding part of driver code for gige ( adapter.c ) is PHY specific and supports Marvel's PHY on ML403 board. Never looked more what it does ( phy interface should be common to all PHYs ? ) but if you use different PHY maybe you'll have to do some coding here ?! ( look for the comments in the driver ) Oh yes, my tree was missing gmii.h file ( found it throuh google - don't remember from where - first google hit :) ! Did some test measurement and comparison with soft EMAC against hard TEMAC + PLB TEMAC and defualt SG DMA mode (3): Amazing performance increase: close to 100% on tcp ( netperf and netio shows over 11000KB/s for max packet size of 32K on 100Mb link ) Hope this helps !

Hi Xavier, I'm trying to get running linux 2.6.17 on my ML403 board (Virtex-4) but I'm having some trouble with the MMU initialization... This my message to the ML: http://ozlabs.org/pipermail/linuxppc-embedded/2006-June/023321.html Did you have similar problems? Have you any idea that could help me? Thank you so much.

This is a patch for ML403 board, it adds the linux 2.6 driver for TEMAC. http://ozlabs.org/pipermail/linuxppc-embedded/2006-March/022365.html Hope this helps. > > Thanks, xavier > > ___ > Linuxppc-embedded mailing list > Linuxppc-embedded at ozlabs.org > https://ozlabs.org/mailman/listinfo/linuxppc-embedded > > Regards, Filippo Capurso -- DAVE Srl - Electronics System House via Forniz 2/1 33080 Porcia (PN) - Italy Telephone: +39.0434.921215 Telefax: +39.0434.1994030 Freefax: +39.02.700520062 web: www.dave-tech.it e-mail: filippo.capurso at dave-tech.it how to reach us: http://mail.map24.com/dave

I have a 2.6.17 kernel compiling and booting but still have little pb with initrd attachement... here is my .config file : you should modify it a little ml300 -> ml400 and modify your xparameters_ml400.h according to the hardware you difined in xps or ise... You should also modify the kernel argument line according to what you need root nfs or whatever you use... xavier Le mardi 20 juin 2006 ? 11:04 +0200, Filippo Capurso - DAVE srl a ?crit : > Hi Xavier, > > I'm trying to get running linux 2.6.17 on my ML403 board (Virtex-4) but > I'm having some trouble with the MMU initialization... > This my message to the ML: > > http://ozlabs.org/pipermail/linuxppc-embedded/2006-June/023321.html > > Did you have similar problems?

Hi, I'm currently running linux with 10/100 MBits xilinx ethernet driver. I have a memec 2VP20 evaluation board. We have bought a PCOM2 module in order to have a Gb PHY. I have implemented an hardware to handle it but whatever linux version I take (2.4 from denx web site, 2.6.17 from kernel.org), I can't configure a Gb ethernet driver. And the 10/100 driver don't configure my Gb PHY... I have compiled my linux kernel based on the ml300 configuration default config. Does anyone has an idea ? Thanks, xavier
