When you power on, you should see something like:

= Booting Linux =

Example:

tftp/nfs server  : <host_ip>
target ip address: <target_ip> 

= booting using a ramdisk =

 * Make a directory /tftpboot/edb and then make sure to:
 {{{
cp rootfs/boot/zImage /tftpboot/edb
cp rootfs.ext2.gz /tftpboot/edb
 }}}

 * Then at the redboot prompt:
 {{{
ip_address -l <target_ip> -h <host_ip>
load -v -r -b 0x800000 edb/rootfs.ext2.gz
load -v -r -b 0x200000  edb/zImage
exec -r 0x800000 -c "root=/dev/ram console=ttyAM0" 0x200000
 }}}

= booting using nfs =

 * Make a symlink to your rootfs directory
 {{{
cd /tftpboot
ln -s <ltib_dir>/edb9302/rootfs <target_ip>
 }}}

 * Export the rootfs directory, edit /etc/exports and add the line:
 {{{
<ltib_dir>/edb9302/rootfs *(rw,no_root_squash)
 }}}
 YES: this is insecure, so if you're worried change appropriately.

 * Re-start/export your nfs server (here's one way)
 {{{
sh /etc/rc.d/init.d/nfs restart
 }}}

 * At the redboot prompt:
 {{{
ip_address -l <target_ip> -h <host_ip>
load -v -r -b 0x218000  edb/zImage
exec -c "root=/dev/nfs ip=<target_ip>:<host_ip>::::: console=ttyAM0" 0x218000
 }}}
alternately:
{{{
exec -c "root=/dev/nfs nfsroot=<host_ip>:<host_rootfs_dir> ip=<target_ip>:<host_ip>::::eth0: console=ttyAM0" 0x218000
}}}


= Change Default RedBoot Parameters in Flash. =

 * To list the default RedBoot parameters:
{{{
fconfig -l
}}}

 * To change some/all the parameters:
{{{
fconfig
}}}

 * This returns each of the line items one at a time, and they can be edited.
   When now editing the variable just hit return to move to the next item.  At
   the end there will be a prompt to Update the RedBoot non-volatile
   configuration.  Answer "y" to update the flash memory.
