3.4 Upgrading the Firmware
It is recommended to have the latest released firmware version installed
on the Atomix LT board. Depending on the currently installed firmware
it may require an upgrade. This can be done with a program named
’atomixltup’. This section explains how to determine whether you need
and how to perform a firmware upgrade.
3.4.1 Determining the Firmware Version
Before upgrading the firmware you have to determine the firmware
version that is currently installed on your Atomix LT board and compare
it with the version suitable for your DVS SDK. For this perform the fol-
lowing:

Open a command line (shell, or in case of Windows command
prompt (cmd)).

Enter at the command line
svram version info
and press
[Enter].

In the output look for the line that says
Firmware Version:
5.4.0.6_5.2.4
or similar.
The numbers indicate the installed firmware version. In detail they
stand for two version numbers that are separated by an underscore, i.e.
with the pattern <v
1
>_<v
2
>.

Next check the
readme.txt
and
changelog.txt
of the DVS
SDK for information about the required firmware version. Notable
dependencies will be stated in these files.
An upgrade should be performed by qualified personnel only.
Before upgrading the firmware close all other applications.
Be aware of a power failure. If this happens, you have to use
the fallback firmware version of the Atomix LT board as de-
tailed in chapter “Maintenance” on page 4-1.
If the driver is not already loaded, load the driver. Further infor-
mation about this can be found in the separate SDK documen-
tation.
In case you have several Atomix LT boards installed, use the
environment variable
SCSIVIDEO_CMD
and set it to
PCI,card:<x>
(with
<x>
as the number of the board, nor-
mally counting from zero (
0
)) to access a particular board.
Please refer to the SDK documentation for details about setting
the variable
SCSIVIDEO_CMD
.
