In the end, this only proves
the vast amount of technol-
ogy hidden inside the S7000.
The total firmware package
consists of files that update
the following components:
• Bootloader v2.32.12
• Kernel v1.2
• Software
v1.01.42/1.01.43-6
• File System
v1.03.49/1.01.30/1.30.05
• CA Module v1.06.1/2.20
In general, meters and re-
ceivers use a so-called boot-
loader to start up. The ac-
tual firmware is stored in the
flash memory and is usually
compressed for reasons of
Deviser
Firmware Upgrade
1. The starting point was the
firmware with Software Version
1.01.36.
2. Upgrade menu of the
Bootloader: connect the
Deviser S7000 to the mains
power supply and turn it on,
while simultaneously pressing
the key with the wrench
symbol.
3. I attached the USB memory
with the upgrade files into a
root folder called “deviser_
s7000”. Then I selected the F2
key for “USB disk”. This opens
the upgrade options using a
USB memory.
4. The first option “CFE
Upgrade” will update the
Bootloader. This is the only
critical step when upgrading
the Deviser S7000: never
interrupt this! First the memory
banks of the flash memory
containing the Bootloader are
deleted.
5. Then the new Bootloader is
written into the flash memory.
Once this process, which
takes less than a minute, is
completed the Deviser S7000
will automatically reboot.
6. If you have no USB memory
at hand you can do the upgrade
through a network connection.
For this to work, you need
to setup a TFTP server and
specify its IP address. The real
benefit of this option is the
possibility to remotely upgrade
the firmware: just instruct the
technician to connect the meter
to the network and have him
press the keys on the device.
This allows safe firmware
deployment without actually
distributing it to end users.
7. If everything went OK you
should see the boot logo of
the Deviser S7000. If you look
at the previous pictures, you
will find an option that actually
allows uploading a different
picture: Splash Upgrade. This
is nice to customize the meter.
Imagine you want to put a name
tag on each meters, so that
different technicians don’t mix
up the individually configured
meters…
8. Leave the USB memory
attached to the Deviser S7000
and it will directly boot into the
firmware upgrade menu. This
application will scan the USB
memory for upgrade packages.
It takes a few seconds to
process the available upgrade
packages.
9. Finally you will be given
the choice to select which
packages you want to install.
You can select the packages
individually or all at once,
pressing the F1 key.
10. At the end of the upgrade
process the Deviser S7000 will
turn itself off. Don’t forget to
detach the USB memory before
turning it on again.
11. After starting again go to
the Setup menu of the Deviser
S7000 to see the current
installed firmware versions
of the different components.
Scroll down to the options page
and you will find the new IPTV
option. This may have been
listed in previous firmware
releases but was not active
due to the beta status. This is
the first software which allows
activation by end users through
a special pin code provided as
a cost option.
12. And here you have it:
my Deviser S7000 is now
prepared for terrestrial TV,
cable TV, satellite TV and IPTV.
A truly complete measuring
instrument for TV technicians
and installers.
13. I selected the option right
away, without any network
cable attached, just to see the
new menus and options.
14. As usual, I tested the
firmware upgrade procedure
exhaustively and I am pleased
to report to our readers, that
you can upgrade or downgrade
the package versions at will,
as sometimes you may need or
prefer to use an older firmware.
You can even select individual
components to upgrade or
downgrade and you can do so
from the automatic upgrade
menu or manually from the
boot loader menu.
efficiency and to save valu-
able resources. By contrast,
the boot loader is not com-
pressed and sits right on
top of everything else. This
makes sure it is run automati-
cally as soon as the device is
turned on. The main task of
a bootloader is to look up the
firmware in the flash memory,
unzip it and copy it into the
RAM memory.
Apart from launching the
firmware, the bootloader is
also required for firmware
updates. During launch, the
bootloader checks whether a
firmware file is available on
an external medium such as
a USB stick, for example. In
to add the feature that is then
activated with a code. If you
decide to unlock IPTV mode
you simply contact Deviser
with the serial number of your
meter to receive the required
activation code.
But first you have to install
the latest firmware release
to get going. For the Deviser
S7000 this update process
requires a little more effort
and time than for most oth-
er meters we have tested so
far. This is because this little
meter is actually a full-scale
computer running the Linux
operating system. Users of
the S7000 generally wouldn’t
know and notice, but for IT
specialists the type of image
files used for firmware up-
