9 Firmware Details
9.1 Firmware Contents
The .firmware file downloaded to the MVI56E-LDM contains a number of files
sourced from the
C:\Workspace folder. Although they are installed on the
module with the module webpage’s Firmware Download process, the files can be
FTP’d independently as well.
If the MVI56E-LDM device does not have any custom software already installed,
then the ThingWorx-LDM sample application can be installed and started by
upgrading the firmware file to the one that was built according to Chapter 4.
When the module is rebooted after the upgrade, the sample application starts (by
script
/etc/init.d/S88-tw ).
If the module has other custom files and/or a Firmware Update is not desirable,
then the following files from
C:\Workapce can be installed over FTP connection
to the module.

S10-syslog
/etc/init.d Optional, for logging.
To enable logging, service syslog should
be started. The service can be started
automatically at system reboot by copying
of the script file
S10-syslog to the folder
/etc/init.d . Note that the script configures
log file location as
/
www/html/log/messages.txt , i.e. under
embedded web server’s content location.
This allows viewing of the log file
’s content
in a web browser at URL
http://192.168.0.250/log/messages.txt (the
IP address of the module needs to be
corrected accordingly).
