i used the following procedure to build the kernel
U-Boot> setenv ipaddr 192.168.1.61
U-Boot> setenv serverip 192.168.1.69
U-Boot> tftpboot 0x80200000 uImage-BBB
U-Boot> setenv bootargs console=ttyO0,115200n8 root=/dev/nfs rw
nfsroot=192.168.1.69:/nfsroot
ip=192.168.1.61:192.168.1.69:192.168.1.100:255.255.255.0::eth0
U-Boot> bootm 0x80200000
i tried with vaious bootargs for nfs booting but no success !!!
[1] setenv bootargs 'console=ttyO0,115200n8 noinitrd,3 root=/dev/nfs
ip=192.168.1.61:192.168.1.69:192.168.1.100:255.255.255.0::eth0 rootwait rw
nolock,rsize=1024,wsize=1024,rootdelay=2 nfsroot=192.168.1.69:/nfsroot '
[2]setenv bootargs 'console=ttyO0,115200n8 noinitrd root=/dev/nfs
nfsroot=192.168.1.69:/nfsroot rw
ip=192.168.1.61:192.168.1.69:192.168.1.100:255.255.255.0::eth0:'
and so on..
pls share your experience to get my kernel bootable...
