This is the code repo for a Web Kiosk Instructable at: https://www.instructables.com/id/Web-Kiosk/
It is based on the ODROID C2 device:
The image that comes on the eMMC card from HardKernel is totally bloated for use as a kiosk, so for this build we'll be using meveric's Debian Stretch image; details about the image can be found here.
Download the ~93MB C2.img.xz image file:
Now, download a tool called Etcher which will allow you to write the image file you downloaded above to the eMMC card.
To do this, use the eMMC2SD card adapter, and insert into a microSD card reader on the computer you'll be running Etcher on.
When you run Etcher you first select the image you downloaded, and then select the microSD card reader, then hit Flash.
NOTE When selecting a drive in step 2, make sure it is your microSD card reader, because if you select another driver, Etcher will overwrite that drive, and the data can't be recovered! I won't be responsible for lost data, so read the instructions on the Etcher download page.
NOTE2 On windows, when you insert the eMMC2SD card adapter, you may get popups about the need to format the drive. IGNORE these dialogs. Just hit cancel, and close any FileManager windows. The same will happen when Etcher starts, and when it finishes. Just close any Windows dialogs that popup.
Once Etcher is complete, you can remove the eMMC2SD card adapter, remove the eMMC card, and insert the card onto the bottom of your ODROID.
For this next step you will need to plug-in a regular HDMI monitor NOT the touchscreen monitor. You'll also need to plugin a keyboard into the ODROID for this first step. The default OS is configured for a 1920x1080px60hz screen, so plugging in the touchscreen will make any text unreadable.
Make sure you have an ethernet cable attached to your ODROID Power up the machine; you'll see a series of startup output. The screen will blank, which is normal as it expands the image onto the full space of the eMMC drive, and the screen will then refill with the startup output, and then blank to the login screen.
apt-get update && apt-get dist-upgrade -y
About mid-way through you'll see a warning about rebuilding the kernel. Just hit ENTER to OK. When the process is complete enter the command:
apt-get install net-tools -y && clear && ifconfig eth0
(write down the IP address and mac-address (the HEX decimals after the word "ether"). You'll need the IP address for SSH login)
