Upgrade
When the Upgrade Main Menu Tool Bar item is selected, the Upgrade page is displayed,
which provides a means to perform a firmware upgrade of the receiver on the network.
Firmware upgrades can comprise application executables and data files, as well as
elements of the Linux operating system kernel and support files. Although the application
firmware specific files are more likely to be upgraded, any file that the receiver requires can
be upgraded. Typically, a valid upgrade file provided by International Datacasting will only
contain the specific files that need to be updated. Such files will be collected into a single
Linux
tarball
upgrade file. Upgrade
tarballs
may also be further compressed with
gzip
to
further improve upload times.
A sample Upgrade page is shown in Figure 4-66.
A detailed description of the upgrade process is provided on the Upgrade page. Should
there be any questions or doubts with respect to performing an upgrade, or what versions of
upgrades to use, please contact your Network Service Provider, or International
Datacasting Customer Service (see Chapter 5).
There are some important rules to consider when performing an upgrade:
1. The file format for the upgrade must be compatible with International Datacasting
specifications for upgrade files. This includes a digital signature, which is contained
within the file for high security upgrades. Generally, upgrades will be supplied to
you either by your Network Service Provider, or via the International Datacasting
Customer Service web site.
2. The version number of the upgrade cannot be the same as the current version of
firmware in the receiver. The current version is displayed on the Upgrade page for
convenience.
3. An internal record of the oldest compatible version number is maintained in the
receiver and determines what minimum version number of firmware can be
upgraded into this receiver. The version number of the upgrade cannot be older
than that version.
4. The upgrade file must be for the correct model of receiver being upgraded (e.g.
SRA2100R, SFX2100B, etc.).
