file downloaded was corrupt or that you forgot to set your FTP download file mode to binary when
downloading the file--either from the EndRun Technologies website or when transferring it to the
RTM3204.
Recovering from a
Failed Upgrade
To restore your RTM3204 to a bootable state using the factory root file system, you must use the
serial I/O port and re-boot the RTM3204 by cycling the power. For setup details refer to sections
Connect the Serial I/O Port
and
Test the Serial I/O Port
in
Chapter 2 - Basic Installation
. When
you have connected your terminal to the serial I/O port, apply power to the RTM3204.
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 GPS
Upgrade
To perform this upgrade, log in as the
root
user to the RTM3204 using either the local console serial
I/O port,
telnet
or
ssh
and perform these operations:
Change the working directory to the
/tmp
directory:
cd /tmp
If you are using
ftp
to perform the upgrade, transfer the previously downloaded file using
binary
transfer mode from the remote host to the working directory,
/tmp
(substitute the name of the GPS
subsystem image that your are installing for
gpsupgrade.bin
):
ftp remote_host
{
perform ftp login on remote host
}
bin
{set transfer mode to binary}
get gpsupgrade.bin
{transfer the file}
quit
{
close the ftp session after the transfer
}
If you are using
ssh
, you may open another command window on the remote computer and securely
transfer the GPS subsystem image to the
/tmp
directory using
scp
from the remote computer. A com-
mand like this could be used:
scp –p gpsupgrade.bin [email protected]:/tmp
Now issue the following command to the RTM3204 console to initiate the upload:
upgradegps /tmp/gpsupgrade.bin
