Updating the Liso firmware should normally be done remotely over the network using Evoko Home (Default mode only) or by using a USB stick, but in some scenarios a firmware reset might be necessary.
A firmware reset is different from a firmware update in that it resets all settings and leaves the Liso in an unconfigured state. After firmware resetting a Liso you will have to reconnect it to Evoko Home and assign it to a room. Scenarios where performing a firmware reset can be necessary include rare issues with the running software on the Liso device or configuration conflicts
If a Liso is running a very old firmware, performing a firmware reset can also be the quickest and easiest way of bringing it up to date.
If you need instructions for a firmware update, please see this article: How do I update the firmware on an Evoko Liso?.
Firmware reset procedure
Part 1: Create a bootable firmware reset USB
To write the firmware reset image to a USB you will need to use some kind of disk imaging software. In the example below we will use Etcher which is open source software that is free to download and use. If you are more familiar with Win32DiskImager or Rufus, those tools also work. Select the tool you are most comfortable with.
- Download and run Etcher from etcher.io. If you do not want to install the software, there is a portable option that can be run directly after download without installing.
- Download a Firmware Reset image available here. Please select the version that corresponds to your Evoko Home install (1.x/2.x). Save the file if prompted.
- In Etcher, click the select image icon.
- Select the firmware reset image you downloaded and press "Open".
There is usually no need to uncompress the image as Etcher will take care of that.
- Insert and select your USB flash drive.
- Click Flash and if promted by Windows UAC click yes.
Caution! All existing data on the USB flash drive will be deleted.
- The process usually takes 5-10 minutes depending on the write speed of the USB flash drive.
- Once Etcher is finished writing your firmware reset USB flash drive it verifies the drive. Then it is ready to use. The USB drive name should now be
Boot imx6dland should contain some new files.
Please note that there are partitions not normally visible by Windows and you might get error messages saying you need to format the drive before it can be used. Please ignore these messages.
Part 2: Boot Evoko Liso with firmware reset USB
Next step is to boot the Liso device from the firmware reset USB rather than the internal storage.
- Power off the Liso by removing the PoE or power cable.
- Insert the firmware reset USB into the Evoko Liso USB port.
- Power on the Evoko Liso by inserting the PoE or power cable and wait.
- If successfully booted from the USB stick the following text should be displayed "If you do not want to flash the device, remove the USB image and reboot the device, otherwise it will start flash in 30 seconds".
- Once the firmware reset is complete, the following text should be displayed "Flash has been successfully completed! Please plug-out the USB and reboot the device."
