Recovering from a Failed RFS Upgrade
To restore your Meridian II to a bootable state using the factory root file system, you must use the
serial I/O port and reboot the Meridian II by cycling the power. Refer to Chapter 2 – Basic Instal-
lation, Connect the Serial I/O Port and Test the Serial I/O Port for setup details. When you have
connected your terminal to the serial I/O port, apply power to the Meridian II.
Pay close attention to the terminal window while the unit is rebooting. After the Linux bootloader
displays the message
Default kernel: FACTORY
To override and boot the UPGRADE version of the kernel,
type UPGRADE within 5 seconds
.....
Booting with FACTORY Kernel
Default Root File System: UPGRADE
To override and boot the FACTORY version of the Root File System,
type FACTORY within 5 seconds
you must begin typing “factory” within five seconds to let the bootloader know that you are going to
override the default root file system. After you hit <enter> the bootloader will boot the factory root
file system. Watch the rest of the boot process to make sure that you have successfully recovered. If
the system boots normally, then you should resolve the problems with the previous root file system
upgrade and re-perform it.
Performing the Linux Kernel Upgrade
First you need to download the Linux Kernel firmware from the EndRun website to a place on your
network which is accessible to the Meridian II. The link to the Meridian II upgrade page is shown
above.
Transfer File to Meridian II
You may transfer the file to your Meridian II using either
ftp
or
scp
. If you are using
ftp
, transfer
the previously downloaded file using binary transfer mode from the remote host to this specific file
on your Meridian II: /tmp/kernel.gz . The kernel image will be named with a software part number
like: 6010-0064-000_2.00.uImage . When following the instructions below, substitute the name of the
actual kernel image that you are installing for 6010-0064-000_2.00.uImage. Issue these commands
from the console of your Meridian II:
ftp remote_host
{
perform ftp login on remote host
}
bin
{set transfer mode to binary}
get 6010-0064-000_2.00.uImage /tmp/kernel.gz
{transfer the file}
quit
{ close the ftp session after transfer }
If you are using
scp
, you may open a command window on the remote computer and securely trans-
fer the kernel image from the remote computer to your Meridian II. A command like this should be
used:
scp –p 6010-0064-000_2.00.uImage root@host.your.domain:/tmp/kernel.gz
