Hello Gopi,
this will definitely not work, because the nfshost and the rootpath variables
will never
be substituted in the bootargs variable. Try the following setup:
bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs mem=116M
bootcmd=set bootargs ${bootargs} nfsroot=$(nfshost):$(rootpath);nboot
0x80700000 0 0x400000;bootm
This way the variables will be correctly substituted and everything should be
working fine...
Best regards,
Kai
