Hi, I am NFS booting with root=/dev/nfs nfsroot=192.168.2.30:/tftpboot/rootfs ip=192.168.2.31:192.168.2.30::::eth0 See if it helps, Alex ----------------------------- Hi list, I have a Malta board for which I was able to build the kernel, load it and start it. The problem comes when it tries to boot through the NFS. I start the kernel with the following command: go . nfsroot=192.168.1.1/mnt/danube_rootfs ip=192.168.1.4:192.168.1.1::: The kernel starts up and I get the following output: ***** BEGIN OUTPUT ***** YAMON> go . nfsroot=192.168.1.1/mnt/danube_rootfs ip=192.168.1.4:192.168.1.1::: Linux version 2.6.22.1-default (danube@peng) (gcc version 3.3.6) #3 Tue Aug 7 18 :59:37 CEST 2007 LINUX started...
