You mentioned you intended to use NFS as root file system. Then I'd expect to see /dev/nfs here. [Note: 'n' != 'p'] > bootcmd=run setboot;bootm 0xfc000000 0xfc300000 You mentioned you intended to use NFS as root file system. Then why do you use a ramdisk? > ## Loading RAMDisk Image at fc300000 ... > Image Name: Taihu Ramdisk > Image Type: PowerPC Linux RAMDisk Image (gzip compressed) > Data Size: 15447973 Bytes = 14.7 MB Your ramdisk image is much bigger than the default maximum kernel ramdisk size (4 MB). But you don't pass any ramdisk size information with your boot arguments: > Kernel command line: root=/dev/pts nfsroot=192.168.2.18:/opt/eldk/ppc_4xx ip=192.168.1.62:::::eth0:off If you really want to use this ramdisk, you should set the root device and the ramdisk size appropriately.
