We recommend using the latest OS image to ensure you have any bug fixes and features released by the Raspberry Pi Foundation. After booting the OS, the software packages can be further updated to the most recent releases of the day by running apt-get update && apt-get upgrade
from a terminal.

The downloads above should be used for all ComfilePi models. However, after imaging the SD card, you may need to update the resolution for any models that are not 800 x 480 (e.g. CPi-A150WR), or use a different display technology (e.g. CPi-A070WT). For those models, simply open the file /boot/config.txt
and edit as described below.

The installation procedure is the same as that used with the Raspberry Pi 3. See “Writing the image” at the Raspberry Pi Installation Instructions
For flashing eMMC models, obtain a USB-A-to-USB-A cable to connect a PC to the ComfilePi's dedicated eMMC programming USB device port, and then follow the Raspberry Pi eMMC Flashing Instructions.
COMFILE Technology maintains and distributes a custom Raspberry Pi OS image for the ComfilePi products. It starts with the original Raspberry Pi OS image, and then introduces the following changes:
sudo apt-get install {package-name}
command./opt/ComfileTech
to support the following features:
Source code for appropriately licensed software can be obtained by executing apt source {package_name}
on the ComfilePi.
