3.4 Upgrading the Firmware

It is recommended to have the latest released firmware version installed

on the Atomix HDMI board. Depending on the currently installed firm-

ware it may require an upgrade. This can be done with a program

named ’atomixhdmiup’. This section explains how to determine wheth-

er 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 HDMI board and com-

pare it with the version suitable for your DVS SDK. For this perform the

following:

 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:

7.4.0.11_7.0.10 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

>_<v

 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 HDMI board as

detailed 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 HDMI 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.
