Upgrade via the
Console Port
In order to upgrade via the console port (network or serial) you will need to first download the appro-
priate firmware image from our website. The Meridian II firmware consists of four different binary
files. You may only need one or two of them. The revision history on our website will tell you which
files need to be upgraded. The firmware image files are for the Linux RFS (root file system), the
Linux Kernel, the GPS Subsystem and the GPS Receiver. Here is the website link:

Performing the Linux RFS Upgrade
NOTE TO LINUX GEEKS
There are two FLASH disk partitions which hold the compressed Linux root file system images. These
partitions are raw FLASH blocks, have no file system and may not be mounted. They are accessed through
low-level device drivers. To protect the factory root file system from accidental erasure or over-writing, the
upgrade utilties you will be using will only access the upgrade root file system partiton. When performing
an upgrade, you will be erasing and then copying the new image to this device.
First you need to download the Linux RFS 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
Some browsers will automatically unzip the file when downloading from the website. Please make sure
that the downloaded file size matches what the website says it should be. Upgrading the partition with a
too-large file size will cause problems.
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/rootfs.gz
. The root file system image will be named with the software part
number and version like:
6010-0067-000_3.00.gz
. When following the instructions below, substitute
the name of the actual root file system image that you are installing for
6010-0067-000_3.00.gz
. Is-
sue 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 6010-0067-000_3.00.gz /tmp/rootfs.gz
{transfer the file}
quit
{
close the ftp session after transfer
}
