Firmware Upgrade

In this document we will focus on Firmware Upgrade.

About Firmware

IPLOG-GAMA firmware is divided into three parts.

Recovery image - This part is a read only image and used to possibility restore the system in the event of a main firmware fatal error of parts Firmware Image 1 and 2.

Firmware Image 1 and 2 - These two parts contain the main firmware images. One is marked as "current", this firmare is running at the present time. When the Firmware Upgrade starts the new Firmware Image is written to the second Image part which is not running. Thanks to this feature, the firmware that works properly can not be damaged. After a successful upload, the new one will startup with the next reboot and market as "current".

root@iplog:~# metel-firmware-version

Shows the current version of Recovery and Firmware images.

Source of New Firmware Image

1. Remote Data Storage

a) Windows

To copy files between IPLOG-GAMA(Linux) and Windows there is a need a third-party tool. For example it is possible to use WinSCP.

• Download, Install and Open the WinSCP.

Connection Configuration

Host name - The IP address of IPLOG-GAMA, the default IP address is on the housing.

User name - The default user name is root and without a password.

Connection Warning

For every new connection there is a Warning message shown, if you trust this remote device, confirm by clicking the YES or NO and this new session will or will not be saved according to your choice.

Upload Firmware Image File (.tar)

Select source file with a new firmware image to upload to the IPLOG-GAMA and click the F5 button to start the upload. For a target location use for example /tmp/ folder.

WinSCP starts image uploading.

After a successful upload close the WinSCP session.

b) Linux

SCP or secure copy allows secure transferring of files between the local host and the remote host or between two remote hosts.

Example:

root@iplog:~# scp root@192.168.6.61:/home/user/12.0.8958.tar /tmp/

Command scp copy file 12.0.8958.tar of /home/user/ folder on remote pc root(user)@192.168.6.61(ip address) to local folder /tmp/ on IPLOG-GAMA.

2. Local USB

For USB there is not a direct command to copy files of USB to IPLOG-GAMA unit, therefore the USB must be "mounted" to some directory at the beginning.

Create a new folder(usb) to /mnt/ directory by command mkdir.

root@iplog:~# root@iplog:~# mkdir /mnt/usb/

Use the dmesg command which typically contains the messages produced by the device drivers.

root@iplog:~# dmesg

This prints the message buffer to the screen. The USB name is typically a sda1.

Mount the USB (sda1) to /mnt/usb directory

root@iplog:~# mount /dev/sda1 /mnt/usb/

Tip: Check the mnt/usb/ folder content by command root@iplog:~# ls /mnt/usb/

Run Firmware Upgrade

Basic command to run the firmware upgrade.

root@iplog:~# metel-firmware /new_firmware_image_destination

How to run the firmware upgrade of "Remote Data Storage" examples (Windows or Linux).

root@iplog:~# metel-firmware /tmp/12.0.8958.tar

How to run the firmware upgrade of "Mount the Local USB" example.

root@iplog:~# metel-firmware /mnt/usb/12.0.8958.tar

Example of the process of firmware upgrading.

valid boot header to partition 4 has been added
invalid boot header to partition 3 has been added
=== UPGRADE DONE ===

After the firmware upgrade restart the device by command "reboot"

root@iplog:~# reboot

Check the successful firmware upgrade. The new firmware was uploaded to not runnig firmware image possition and after device reboot used as current (running).

root@iplog:~# metel-firmware-version
