Update the Firmware and Bootloader
The GM02 Firmware and Bootloader should be updated after the Mesh Node is installed to ensure that it is running the latest version. The Firmware and Bootloader update files are in tar.gz format.
Update the Firmware
To update the firmware:
Get the latest firmware from your GXC representative or GXC partner and download it onto the laptop that you will be using to update the GM02.
Compare the version number of the firmware tar file and the firmware currently running on the GM02 to determine if an update is required.
The firmware version number of the tar file is part of the file name, for example, “tr0_fw_pkg_1.3.544.tar.gz”.
The firmware version currently running on the GM02 is displayed at the top right side of the Mesh Node’s Status webpage, for example “1.3.544”.
Click the FW UPDATE link at the top right side of the web page.
Click to select the Firmware checkbox and then click Select File.
Navigate to the location on your laptop where the appropriate firmware tar file is located, click to select it, and then click UPLOAD.
A progress bar will indicate the status of the upload and Upload Completed will appear below the UPDATE button once the upload is complete.
Once the file is uploaded, click UPDATE and a prompt will appear (“System will be automatically rebooted after the update. Are you sure to update?”). Click Yes to update or No to abort. The update process should take several minutes to complete and will automatically reboot the unit when it’s done following a brief countdown.
After the GM02 reboots, you must manually refresh the browser to get back to the Mesh Node’s Status webpage. Check the firmware version number at the top right side of the page to confirm that the GM02 is running the correct firmware version.
Update the Bootloader
To update the bootloader:
Get the latest Bootloader tar file from your GXC representative or GXC partner and download it onto the laptop that you will be using to update the GM02.
Compare the version number of the Bootloader tar file and the Bootloader currently running on the GM02 to determine if an update is required.
The Bootloader version number of the tar file is part of the file name, for example, “tr0_xxxxxx.tar.gz”.
The Bootloader version currently running on the GM02 is displayed on the System page. Click the System link at the top right side of any of the Mesh Node’s webpages. The Boot Loader version is shown in the Firmware Version section of the page; for example, “v1”.
The Bootloader update process is the same as the firmware update process as described in the previous section.
Switch Firmware Version
The Mesh Node’s memory has multiple partitions. Initially, the contents of all partitions are identical, and the GM02 system boots from the primary partition.
When the first firmware update occurs, the new image is written to the secondary partition (because the system cannot overwrite the partition from which it booted). The partition with the new firmware update image is set to “Active” and the system reboots. At that point, the “primary” partition becomes the backup system (previous image) and the system will revert to it if the new image fails to reboot.
When the second firmware update occurs, the “Primary” partition is overwritten with the new image, set to “Active” and then system reboots. At this point, the “Secondary” partition becomes the backup. Further updates repeat this cycle.
You have the option to switch between the most recently installed version of the firmware and the previous version. A manual reboot is required after activating a different version of the firmware.
To switch between firmware versions:
Click the System link at the top right side of any of the Mesh Node’s webpages.
In the Firmware Version section of the page, click the Activate button beside the version of the firmware that is not currently running.
On the Firmware page, click Reboot to manually reboot the GM02.
