First erase the upgrade partition by issuing this command at the shell prompt:
eraserootfs_1
If you are using
ftp
to perform the upgrade, transfer the previously downloaded file using binary
transfer mode from the remote host to /dev/rootfs_1 on your RTM3204 using FTP (substitute the
name of the root file system image that you are installing for rootfsupgrade.gz ): Issue these com-
mands from the console of your RTM3204:
ftp remote_host
{
perform ftp login on remote host
}
bin
{set transfer mode to binary}
get rootfsupgrade.gz /dev/rootfs_1
{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 RTM3204. A command
like this should be used:
scp –p rootfsupgrade.gz root@gsys.your.domain:/dev/rootfs_1
Update the default file system partition by issuing this command on your RTM3204.
updaterootflag 1
You should see this line displayed:
UPGRADE is the default root file system.
Now reboot the system by issuing this command at the shell prompt:
shutdown –r now
Wait about 30 seconds for the system to shutdown and re-boot. Then log in to the RTM3204/Tycho
using
telnet
or
ssh
. If all has gone well, you should be able to log in the usual way. After you
have entered your password, the system message will be displayed. You should notice that it now
indicates the software version and date of the upgrade that you previously downloaded. You can also
check this at any time by issuing
gsysversion
which will cause the system message to be re-displayed.
You can also check to see which root file system image the system is currently booted under by issu-
ing this command at the shell prompt:
gsysrootfs
Which should cause this to be printed to the console:
BOOT_IMAGE=TychoGPS_1
If so, and your unit seems to be operating normally, you have successfully completed the upgrade.
If your unit does not boot up successfully, and you are not able to
telnet
or
ssh
into the system
after 30 seconds, then there has been some kind of problem with the upgrade. It is possible that the
