I tried compiling the 2.6 kernel but i failed when i try to bootload it.
So, what i did is I booted my laptop on Linux, installed the NFS from
embeddeArm and after insmod bootloader.o i tried bootloading with the
following command (taken from embeddedArm website :
bootload -c "console=ttyAM0,115200 ip=dhcp init=/sbin/init
root=/dev/nfs nfsroot=132.210.200.92:/root/ts/tmp/mnt/" zImage
where 132.210.200.92 is my laptop's ip.
So it says Uncompressing linux......
reboots, does all kinds of things until it says :
"
Looking up port of RPC 100003/2 on 132.210.200.92
The programs included with the Debian GNU/Linux
portmap: server 132.210.200.92 not responding, timed out
the exact dist
Root-NFS: Unable to get nfsd port number from server, using default
individual files
Looking up port of RPC 100005/1 on 132.210.200.92
VFS: Unable to mount root fs via NFS, trying floppy.or information

les
Module bootloader loaded, with warnings
Please append a correct "root=" boot option00:src# bootload -f
"console=ttyam0,115200
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(2,0)
0.200.92:/root/ts/tmp/mnt/ ip=dhcp init=/sbin/in
"
I'm not really familiar with these kind of procedures so I'm not sure
what might be wrong here...
Does anyone have an idea what the fix could be here?
Thanks
