Installing a firmware upgrade file on a LAN web server
In corporate networks, it is advisable to change the Firmware upgrade URL from the default WML
web server in order to take control of firmware upgrades. A new upgrade can be tested on a sample
unit before being rolled out across the organisation.
The firmware image is around 40 megabytes in size and will take some time to upgrade over a regular
broadband internet connection, providing a further reason to install the firmware upgrade on a LAN
server.
Firmware upgrade images are distributed as a gzipped tar archive containing several files. The latest
image is always available at http://wmltd.co.uk/foundrylinux/. At the time of writing, the most recent
firmware is: st168wml128-20080820_1233.tar.gz. http://wmltd.co.uk/ foundrylinux always contains
both the archive file and the contents of the archive file.
This archive contains the following files:
● boot.tar
● boot.tar.md5
● persist.tar
● persist.tar.md5
● preupdate.sh
● preupdate.sh.md5
● rootfs.img
● rootfs.img.md5
● version.txt
All of these files should be available from the Firmware upgrade URL – the thin client downloads the
files separately, rather than downloading and untarring the archive file itself.
