This method describes how to boot Linux from the Network and have the root filesystem mounted through NFS:

· The script build-linux-2.6.23.sh should have build the kernel image as /tftpboot/ AT91SAM9260/uImage

· Customize the root filesystem build script build-rootfs.sh

· Then run it, that will generate the root filesystem (let’s say here: /cross-stuff/armle/AT91SAM9260/rootfs/)

· Power the ATSAM9260-EK board and be sure that you a terminal program running (such as minicom).

· Customize the u-boot environment variables to have this (of course adjust to your network):

baudrate=115200

ethaddr=00:01:AF:52:02:59

hostname=atmel

bootfile=AT91SAM9260/uImage

bootargs=root=/dev/nfs rw nfsroot=192.168.0.2:/cross-stuff/armle/AT91SAM9260/rootfs ip=192.168.0.60:192.168.0.2:192.168.0.2:255.255.255.0:atmel::off

boot_addr=0x21400000

nfs_linux=tftp $(boot_addr) AT91SAM9260/uImage

filesize=138F1C

fileaddr=21400000

netmask=255.255.255.0

ipaddr=192.168.0.60

serverip=192.168.0.2

bootcmd=run nfs_linux ; bootm

bootdelay=3

stdin=serial

stdout=serial

stderr=serial

· Reboot your board. If all goes well, u-boot should load the kernel, which should mount the root filesystem over NFS.
