[edit] Configure NFS Root
To boot from NFS, add the following entry via serial console: (See U-Boot section on how to access an bootloader):
setenv bootargs_nfs root=/dev/nfs nfsroot=192.168.0.200:/export/openmoko ip=192.168.0.202:192.168.0.200:192.168.0.200:255.255.255.0:ezx:usb0:off rootdelay=5 console=ttySAC0,115200 console=tty0 loglevel=8 setenv menu_5 Boot from NFS: setenv bootargs \${bootargs_nfs} \${mtdparts} \; nand read.e 0x32000000 kernel\; bootm 0x32000000 saveenv
[edit] Use Static MAC Addresses
The random MAC addresses generated by the USB Ethernet gadget code caused me some grief on the host side. To generate static addresses, I added the following variable to the menu_5 bootargs:
setenv bootargs_usb g_ether.host_addr=00:1b:11:1b:08:18 g_ether.dev_addr=00:1b:11:1b:08:19
[edit] Configure Your Firewall
Another thing to keep in mind is your firewall. I was getting messages like this:
Looking up port of RPC 100003/2 on 192.168.0.200 portmap: server 192.168.0.200 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 100005/1 on 192.168.0.200 portmap: server 192.168.0.200 not responding, timed out Root-NFS: Unable to get mountd port number from server, using default mount: server 192.168.0.200 not responding, timed out Root-NFS: Server returned error -5 while mounting /srv/root
After I updated my firewall to pass NFS traffic over the interface to the Neo1973, everything worked smoothly.
