Firmware Upgrade

Under Construction!

In this document, we will focus on the Firmware Upgrade

About Firmware

Firmware on IPLOG-GAMA is divided to three parts.

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

Firmware Image 1 and 2 - This two parts contains the main firmware images. One is marked as "current", this firmare is running right now. When Firmware Upgrade starts the new Firmware Image is written to the second Image part which is not running. Due to this feature can not damage the firmware that works properly. After successful upload is marked the new one, the next startup will boot of it.

root@buildroot:~# metel-firmware-version

Shows the current version of Recovery and Firmware images.

root@buildroot:~# root@iplog:~# metel-firmware-version

Source of New Firmware Image

1. Remote Data Storage

a) Windows

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

• Download, Install and Open the WinSCP.

Connection Configuration

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

User name - Default user name is root and no password.

Connection Warning

For every new connection is there Warning message if you trust the remote device. Confirm by hit the YES or No and this new session will not be saved.

Upload firmware image file (.tar)

Select source file to upload to the IPLOG-GAMA and hit the F5 button to start upload. As a target location use for example /tmp/ folder.

WinSCP starts image uploading.

After successful upload close the WinSCP session.

b) Linux

SCP or secure copy allows secure transferring of files between a local host and a 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. Mount the Local USB

For USB is not direct command how 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

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

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

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

Shows the mnt/usb/ folder content.

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

3. Run Firmware Upgrade

Basic command to run the firmware upgrade.

root@iplog:~# metel-firmware

Runs the firmware upgrade of "Remote Data Storage" examples

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

Runs the firmware upgrade of "Mount the Local USB" example

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

Print of process firmware upgrading.

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

After 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
