Acquisition Modules and Platinum Firmware
Platinum Firmware Upgrades
5.3.2.1 Downloading the mirror content
The mirror can occupy a significant amount of disk-space, depending on
which architectures you need to support. See the sections for each
architecture (below) for the current space requirements. You should pick a
file-system with ample space in which to store your own copy. In order to
simplify the download, we recommend that you start with an empty directory
each time. If you wish to make a fresh copy after a new firmware release, it is
much easier to create this in an empty directory than to "update" an existing
mirror. You can keep multiple, simultaneous versions of the firmware if you
wish and tell each acquisition device which version to use when upgrading.
The server on which you create the mirror should have access to the Internet
during the download step but does not need Internet access while it is acting
as an upgrade server. It does, of course, need to be accessible by your
networked acquisition devices. It is possible to create the mirror content on a
removable mass storage device attached to an Internet-connected computer
and then move the device to a different computer when performing the
upgrades. The removable mass storage device must use a Linux-compatible
file-system, such as ext3. FAT- and NTFS-formatted devices will not work
properly for this purpose.
Create the mirror directory and use the cd command to make it your current
directory. As root, enter one or more of the following command sequences to
download the mirror content. Each sequence downloads the files for a
particular architecture. If you know, for example, that you will never want to
upgrade a CMG-NAM64, you can omit the commands for this architecture.
Note: Be careful not to omit the final ‘.’ or the space before it in the
rsync commands below.
CMG-DCMs
This architecture currently requires around 50MB of mass storage device
space for the mirror. The commands to download the content are:
GSLSRC=rsync.guralp.com/platinum-stable/CMG-DCM-mk2x
rsync -EgHloprtv --exclude resolv.conf rsync://$GSLSRC .
CMG-EAMs
There are currently two sets of firmware available for the CMG-EAM: a frozen
image of build 3801 (for users who do not yet wish to upgrade to post 10,000
builds) and the latest build.
If you do not wish to upgrade beyond build 3801 yet, the files for build 3801
require around 53MB of storage space for the mirror. Use the following
commands:
