<P>
hi<BR>
<BR>
I am using Taihu Amcc PPC 405EP kit it already contains the U-boot, Linux kernel image, and ramdisk image. I connected the kit using c-kermit on fedora core 4 and installed eldk tools and added it (/opt/eldk/ppc_4xx) to NFS sharing.<BR>
While booting on kit I passed kernel arguments as <BR>
setenv bootargs root=/dev/nfs nfsroot=192.168.2.18:/opt/eldk/ppc_4xx ip=192.168.1.62:::::eth0:off<BR>
<BR>
but the kernel is failed to mount on /dev/nfs as below please can you provide necessary steps to fix the problem.<BR>
I am waiting for your response. <BR>
