downloaded was corrupt or that you forgot to set your FTP download file mode to binary when down-
loading the file--either from the EndRun Technologies website or when transferring it to the Tempus
LX.
Recovering from a
Failed Upgrade
To restore your Tempus LX to a bootable state using the factory root file system, you must use the se-
rial I/O port and re-boot the Tempus LX by cycling the power. Refer to
Chapter 2 – Connect the Se-
rial 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 Tempus LX.
Pay close attention to the terminal window while the unit is re-booting. After the Linux bootloader
displays the message
To override and boot the FACTORY partition 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 upgrade and re-
perform it.
Performing the Linux
Kernel Upgrade
If you want to upgrade your kernel to the IPv6-capable one then you must first be sure that your root
file system is version 2.60 or later.
To upgrade your kernel, log in as the
root
user to the Tempus LX using the local console serial I/O
port,
telnet
or
ssh
and perform these operations:
If you are using
ftp
to perform the upgrade, transfer the previously downloaded file using
binary
transfer mode from the remote host to a temporary location on your Tempus LX using FTP. The IPv6
kernel image will be named with the software part number like:
6010-0041-100.bzimage
. Substitute
the name of the actual kernel image that you are installing for
6010-0041-100.bzimage
. Issue these
commands from the console of your Tempus LX:
ftp remote_host
{
perform ftp login on remote host
}
bin
{set transfer mode to binary}
get 6010-0041-100.bzimage /tmp
{transfer the file}
quit
{
close the ftp session after transfer
}
If you are using
ssh
, you may open a command window on the remote computer and securely trans-
fer the root file system image using
scp
from the remote computer to your Tempus LX. A command
like this should be used:
scp –p 6010-0041-100.bzimage [email protected]:/tmp
The kernel upgrade utility is executed with a single argument passed on the command line: the path
to the previously uploaded kernel image file. For example:
