For example, the environment variables set for this mode might be:
bootargs=mem=120M console=ttyS0,115200n8 root=/dev/hda1 rw
noinitrd ip=dhcp
bootdelay=3
baudrate=115200
bootfile=library/davinci/0.4.2/uImage (NOT USED)
serverip=192.168.160.71 (NOT USED)
bootcmd=bootm 0x2050000
stdin=serial
stdout=serial
stderr=serial
ethaddr=00:0e:99:02:51:46

A.5.2 Booting via TFTP Using Board’s Hard Drive 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 bootargs mem=120M console=ttyS0,115200n8
root=/dev/hda1 rw noinitrd ip=dhcp
EVM # setenv serverip < your_tftp_server_ip_address >
EVM # setenv bootfile < path_on_tftpserver >/uImage
For example, the environment variables set for this mode might be:
bootargs=mem=120M console=ttyS0,115200n8 root=/dev/hda1 rw
noinitrd ip=dhcp
bootdelay=3
baudrate=115200
stdin=serial
stdout=serial
stderr=serial
ethaddr=00:0e:99:02:51:46
serverip=xxx.xxx.xxx.xxx ( your tftp server )
bootcmd=dhcp;bootm
bootfile=tftp_path/uImage
