Preparing the POP Kiosk Software
Flashing an SD Card
First, we will need to download the software required to write the image to the SD card. Using a web browser, navigate to https://www.balena.io/etcher/ and download the latest version available for your current operating system. BalenaEtcher supports Microsoft Windows, Apple MacOS and Linux. Once Balena Etcher is downloaded, open the program.
When BalenaEtcher is open, you will be presented with the main menu. To flash an image to an SD card, we must first direct BalenaEtcher to it.
There are three versions of the POP operating system image; one with CLIO pre-installed, one with OctoPrint pre-installed and one with no graphical user environment pre-installed. Click on ‘Flash from File’ and navigate to the appropriate image downloaded from our website. Select the image file and hit open.
Next, we will need to plug our desired SD card into the computer. Using a MicroSD to USB adapter, plug in the SD card to your computer. Click on ‘Select target’.
Search through the list of devices and find your SD card, using the name and size. By default, BalenaEtcher will only show externally connected devices, such as USB flash drives or hard drives. All system drives and internal hard drives are hidden, decreasing the risk of flashing the wrong SD card.
Once you’ve selected the SD card, you can hit flash to begin copying over the image. In order to do this, you will need to enter the password of a computer administrator. Operating systems, such as MacOS, may require you to allow different access rights. After permission has been granted, the data will begin to transfer and should not require user interaction.
BalenaEtcher will verify all of the data written to the SD card before finishing. Once it is completed, you will be presented with the success screen. If you are making additional kiosks, you have the option to begin flashing another SD card.
Installing the SD Card
After your SD card has been flashed, you can install it into a Raspberry Pi. The SD card slot is located on the underside of the Raspberry Pi computer, on the side opposite from the USB ports. After it is installed, you can plug in the USB power cord into the kiosk to test it.
