This article describes how to update the LTOS (LANTIME Operating System) firmware when a LANTIME is running LTOS V6 or LTOS V7.
In principle, there are 3 different ways how to perform the update.
It can be done via…
Connect to the web interface and open the Firmware/Software Update
menu on the System
page. Use the Browse
button to select the update file from your local hard drive. Once the file has been selected, the update can be started pressing the Start Update
button:
After the upload has finished, you are prompted to confirm the start of the update process. If you tick the Automatically activate new firmware and reboot device after a successful update.
checkbox, the LANTIME will automatically reboot and come up with the new firmware. If you don't tick the checkbox, you can activate the new firmware later on the System
page –> Configuration & Firmware Management
/www/htdocs/upload
using SCP/WinSCP or copy the file to an USB stick (FAT32 filesystem) and plug it in the USB front connector of your LANTIMEroot
and the password is timeserver
.sudo chkupdate /www/htdocs/upload/[name of updatefile]
or in the case the update file is stored on an USB stick:
sudo chkupdate /mnt/usb_storage/[name of updatefile]
so for example:
sudo chkupdate /www/htdocs/upload/firmware-7.06.009-x86.rel
fwlist
Example output of the fwlist command:
OSV fw_7.04.018 fw_7.06.009
sudo fwselect [name of firmware]
Enter the name of the firmware as it's displayed in the output of the fwlist command. So for example:
sudo fwselect fw_7.06.009
sudo reboot
The update can also be installed by using an USB stick. Please make sure that the stick is using the FAT/32 filesystem. Copy the LANTIME updatefile to the USB stick and plug the stick in the USB connector of your LANTIME.
Once the stick has been inserted, the following message should appear in the display:
Proceed with OK
. You will now be able to choose between various options using the “Arrow up” and “Arrow down” buttons of the LANTIME. The LANTIME will automatically detect the existing updatefile on the usb stick and provide the update option.
Press OK
again to start the update process.
After installation of a new firmware via USB stick, the firmware needs to be manually activated using CLI or WebUI. This has already been described in the previous chapters.
