Default kernel: UPGRADE
To override and boot the FACTORY version of the kernel,
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 kernel. After you hit <enter> the bootloader will boot the factory kernel. 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 kernel upgrade and re-perform it.
Performing the GPS Subsystem Upgrade
This section has instructions for upgrading the GPS Subsystem. If you want to upgrade the GPS
Receiver, see the section below called Performing the GPS Receiver Upgrade .
First you need to download the GPS Subsystem 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.
CAUTION
Before proceeding, use the
gpsversion
command to confirm that the firmware number of your GPS
Subsystem is: F/W 6010-0076-000
If it is different (for example: F/W 6010-0076-101), then contact the factory.
You may transfer the file to your Meridian II using either
ftp
or
scp
. If you are using
ftp
to per-
form the upgrade, transfer the previously downloaded file using binary transfer mode from the remote
host to this specific file on your Meridian II: /tmp/subsys.bin . The GPS Subsystem image will be
named with the software part number and version like: 6010-0076-000_3.01.bin . When following
the instructions below, substitute the name of the actual GPS Subsystem image that you are installing
for 6010-0076-000_3.01.bin . You will be transferring the file to a temporary file, /tmp/subsys.bin on
your Meridian II.
ftp remote_host
{
perform ftp login on remote host
}
bin
{set transfer mode to binary}
get 6010-0076-000_3.01.bin /tmp/subsys.bin
{transfer the file}
quit
{ close the ftp session after the transfer }
If you are using SSH to perform the GPS Subsystem upgrade, you may open another command
window on the remote computer and securely transfer the GPS Subsystem image to /tmp/subsys.bin
using
scp
from the remote computer. A command like this could be used:
scp –p 6010-0076-000_3.01.bin root@host.your.domain:/tmp/subsys.bin
Now issue the following command to the Meridian II console to initiate the upload:
upgradesubsys
This command performs the file transfer to the GPS Subsystem. You will see a file transfer progress
