upgradegps
This script allows the user to upgrade the GPS subsystem firmware. It requires one argument: the
path to the binary file to be uploaded to the GPS engine. It issues the commands over the serial
port to the GPS subsystem that are needed to start the X-modem file transfer, and then displays
the responses from the GPS subsystem to the console. When the X-modem ‘C’ character appears,
indicating that the GPS subsystem is ready to receive the file, you must hit the <ENTER> key, and
the transfer will begin. After about one minute, it should complete, at which point you should see the
GPS subsystem boot messages appear on the console. From these, you will be able to verify that the
firmware was successfully upgraded.
In the example console output below, lines which begin with “---” are generated by the
upgradegps
script. All other lines are from the GPS subsystem, with the exception of the shell message indicat-
ing that the process
cat < /dev/arm_user
has been terminated, which is normal. In this example,
the ‘C’ character was received three times before the user hit the <ENTER> key to begin the transfer.
The last three lines are the boot messages that are sent by the GPS subsystem as it comes up. The
firmware version should match that of the binary file that was uploaded. See Performing the GPS
Upgrade
in
Appendix B - Upgrading the Firmware
for more information.

upgradekernel
This script allows the user to change the Linux kernel firmware. It requires one argument: the path
to the file to be uploaded to the Tempus LX. Changing the Linux kernel firmware will enable IPv6
operation and should only be done if you have a requirement for IPv6. See
Chapter 7 - IPv6 Infor-
mation and Performing the Linux Kernel Upgrade in Appendix B - Upgrading the Firmware for
more information.

upgradekernel /tmp/newkernelimage
Tempus LX response: Interactive shell script is started.
