13.6.2 eWON firmware upgrade step-by-step
13.6.2.1 Upgrading from version 3 to version 4
Firmwares versions 3 and 4 are very different, that is the reason why the flash action erases all of the existing files from the eWON
(configuration and user files), and the eWON IP address too.
• The step-by-step process described below is the standard process that we advise you to follow to be sure
to stay on the safe side when performing the eWON's firmware upgrade from version 3 to version 4:
• Download the required eWON's firmware version from the eWON website http://www.ewon.biz/
(/Support/Download software) to your
local disk. Double check that you download the correct firmware version (version 3 to version 4)
. The file you will download will be a
zipped (compressed format) file, that contains the ewonfwr.edf file.
• Open a FTP session on your eWON, by using a FTP client software, such as SMART FTP, that is available for download on the eWON
web site http://www.ewon.biz/
(/Support/Resource Links). Please refer to chapter “FTP transfer” on page 120.
• Backup your current eWON user and configuration files, by downloading them from the eWON FTP site to your local disk, because all
of those files will be erased during the upgrade firmware process. You will be able to upload them on your eWON when the upgrade
process is complete. The files you may want to keep are:
• the eWON configuration files (config.txt and comcfg.txt)
• the file containing your Basic script (program.bas)
• the files that contain the information about the Tags you have created (var_lst.txt, var_lst.csv, ircall.bin)
• the historical logs for each of the Tags for which you have selected this option
• the user website you have created, which is stored in the usr folder (and its subfolders)
• Verify the files you have just downloaded, in order to check that no information could have been lost during the FTP transfer
• Verify that the version 4 firmware you have downloaded in step 1 IS NOT in the same folder as your eWON files you have just
downloaded (in order to be sure not to upload again the firmware in the eWON when you will upload your user and configuration files,
at the end of the process)
• You are now ready to migrate from version 3 to version 4... Upload the firmware ewonfwr.edf file using the FTP tool, by dragging it
from the local folder on your hard disk on which you have stored it, towards the root of the eWON's FTP site.
Nothing will happen until the FTP connection is alive
• In order to initiate the writing operation of the new firmware on the eWON flash memory, select the "Disconnect" command from the
FTP client software. The upgrade process now begins...
• WARNING: Process takes some time and eWON cannot be disconnected during that time, please refer to chapter “Monitoring of
eWON's behavior during the flashing operation” on page 232
• When eWON comes back to its usual state, you now have to define its IP address, as its settings are now the factory settings
(IP address=10.0.0.53). You will have to use the eBuddy tool that is provided for free on http://www.ewon.biz
(/Support/Download software).
• Please refer to the Technical Note 28 “eBuddy User Guide” you will find on http://www.ewon.biz
(/Support/Documentation/Technical notes), which describes the eWON IP address definition process with eBuddy.
Your eWON is now a firmware version 4 eWON, you now just have to browse it with your Internet explorer to discover its new features.
13.6.2.2 Upgrading from version 4 to version 4
There is no loss of files neither than configuration settings when upgrading from a version 4.xx to a newer 4.xx version, then performing a backup
of your configuration and user files is not absolutely mandatory, as it is the case when upgrading from version 3 to 4.
However, you can do this backup if you want to be sure to stay on the safe side, because i.e. a casual power loss during writing operation
in the flash memory may cause severe damages to your eWON, as it is the case for every computer.
The steps to follow to upgrade from a version 4 to a version 4 firmware are then:
• Download the required eWON's firmware version from the eWON website http://www.ewon.biz/
(/Support/Download software)
to your local disk. Double check that you download the correct firmware version (i.e. version 4.01 to version 4.02)
• Open a FTP session on your eWON, by using a FTP client software, such as SMARTFTP, that is available for download on the eWON
web site http://www.ewon.biz/
(/Support/Resource Links). Please refer to chapter “FTP transfer” on page 120.
• Upload the firmware ewonfwr.edf file using the FTP tool, by dragging it from the local folder on your hard disk on which you have
stored it, towards the root of the eWON's FTP site. Nothing will happen until the FTP connection is alive (while you are connected)
• In order to initiate the writing operation of the new firmware on the eWON flash memory, select the "Disconnect" command from the
FTP client software. The upgrade process now begins. The behavior of the USER led is identical as for upgrade from version 3 to 4
(please refer to the chapter that follows: “Monitoring of eWON's behavior during the flashing operation” on page 232.
• When flashing process is complete, you are now able to browse your eWON website and FTP site, running the newly firmware
version, without having to redefine the IP address or having to set again the communication settings from the eWON.
