Booting via TFTP Using NFS File System
To boot in this mode, set the following parameters after you abort the
automatic boot sequence:
EVM #
setenv bootcmd 'dhcp;bootm'
EVM #
setenv serverip 192.168.160.71
EVM #
setenv bootfile library/davinci/0.4.2/uImage
EVM #
setenv rootpath /exports/useracct
EVM #
setenv nfshost 192.168.160.57
EVM #
setenv bootargs console=ttyS0,115200n8 noinitrd rw
ip=dhcp
root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock
mem=120M
For example, the environment variables set for this mode might be:
bootdelay=3
baudrate=115200
stdin=serial
stdout=serial
stderr=serial
ethaddr=00:0e:99:02:51:46
bootcmd=dhcp;bootm
serverip=192.168.160.71
bootfile=library/davinci/0.4.2/uImage
rootpath=/exports/useracct
nfshost=192.168.160.57
bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp
root=/dev/nfs nfsroot=192.168.160.57:/ex
ports/useracct,nolock mem=120M eth=00:0e:99:02:51:46
When you boot, look for the following lines that confirm the boot mode:
TFTP from server 192.168.160.71; our IP address is
192.168.161.186
Filename 'library/davinci/0.4.2/uImage'.
