It should be mentioned in method 1 under dhcp<br /> <br /> setenv nfs_serverip your-workstation&#039;s-ip <br /> setenv nfs_root /path/to/neuros-bsp/rootfs/fs <br /> <br /> These are required in /etc/init.d/mountall.sh for NFS mounts.<br /> <br /> ----<br /> <br /> For an Ubuntu x86_64 system, you need to install the libc6-i386 package in order for the build script to work.<br /> <br /> ----<br /> <br /> == DHCP Booting==<br /> <br /> From http://wiki.neurostechnology.com/index.php/Derobert%27s_Guide_to_the_On-Screen_Display:_NetBooting_the_OSD<br /> <br /> ==== Method 1 ====<br /> <br /> &#039;&#039;You must perform the [[Derobert&#039;s Guide to the On-Screen Display: DHCP Server Setup|optional DHCP server setup]] in order to use this method. This is the preferred method, but is generally only available if you&#039;re using a full DHCP server, not a SoHo router. It&#039;s not the most common situation.&#039;&#039; <br /> <br /> This method is very easy, as nearly all the configuration information is stored on the DHCP server. The alternative is to store it all on the OSD as in [[#Method 2|Method 2]] below.<br /> <br /> setenv bootargs $(console) root=/dev/nfs rw ip=dhcp $(mem_reserve)<br /> setenv bootcmd dhcp\; bootm<br /> setenv nfs_serverip 192.168.0.1 <br /> setenv nfs_root /srv/neuros-osd-rootfs <br /> saveenv<br /> <br /> == Reverting to booting from flash ==<br /> <br /> If you want to revert to booting from flash, you can just do <br /> <br /> setenv bootcmd run cramfs_boot<br /> saveenv<br /> boot<br /> <br /> Or you can just boot from flash once by doing<br /> <br /> run cramfs_boot<br /> <br /> == NFS Mounting Options ==<br /> <br /> To mount NFS drives create the following files in /mnt/OSD<br /> <br /> rc.user:<br /> #!/bin/sh<br /> sh /mnt/OSD/bootscript.sh &amp;<br /> <br /> bootscript.sh:<br /> #!/bin/sh<br /> <br /> sleep 10;<br /> mkdir /mnt/tmpfs/mount_CF-card/data/shortcuts/data;<br /> <br /> mount -t nfs 192.168.0.1:/data /mnt/tmpfs/media/ext/data/shortcuts/data -o rw,nolock,tcp,nfsvers=3;</div>
