5.5.8. Update Firmware
LARA is a complete standalone computer. The software it runs is called the firmware. The firmware
of LARA can be updated remotely in order to install new functionality or special features.
A new firmware update is a binary file which will be sent to you by email or which you can download
from the Peppercon Web site.
Before you can start updating the firmware of your LARA the new firmware file must be accessible
on the system that you use for connecting to LARA.
Updating the firmware is a three-stage process:
ˆ
Firstly the new firmware file is uploaded onto LARA. In order to do that you need to se-
lect the file on your local system using the browse button of the Upload Firmware panel
(see Figure
5.27 ). Once the firmware file has been uploaded, it is checked whether it is a valid
firmware file and whether there were any transmission errors. In case of any error the Upload
Firmware function will be aborted.

ˆ
Secondly, if everything went well, you see the Update Firmware panel (see Figure 5.28 ). The
panel shows you the version number of the currently running firmware and the version number
of the uploaded firmware. Pressing the update button will store the new version over the old
one. Attention: this process is not reversible and might take some minutes. Make sure the
LARA’s power supply won’t be interrupted during the update process, because this may an
unusable device.
ˆ
Thirdly, after the firmware has been stored, the panel will request you to reset LARA manu-
ally. Half a minute after the reset, LARA will run with the new firmware version and should
be accessible. However, you are requested to login once again.
