Raspberry Pi OS

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 full-upgrade from a terminal.



The latest OS image above can be used for all ComfilePi models, but it is preconfigured for the CPi-A070WR, CPi-B070WR, and the CPi-A102WR. For other models, please replace the /boot/config.txt file with the appropriate model-specific one which is included in the /boot directory.

For OS images prior to 2022-07-26 overwrite /boot/config.txt with one of the following:

Installation Instructions

The installation procedure is the same as that used with the Raspberry Pi 3. See “Installing Images…” at the Raspberry Pi Installation Instructions. From the “Choose OS” menu, select “Use Custom” and then browse the OS downloaded from the links above.

For flashing eMMC models, use the following procedure:

  1. Obtain a USB-Type-A-to USB-Type-A cable and connect it between the CPi panel PC and your desktop PC using the “USB Device” port
  2. Turn on the CPi-xxxx panel PC. Due to the USB cable being plugged into the USB Device port, it will automatically boot into a special mode allowing the eMMC to be flashed. Nothing will appear on the screen though. If it boots into the desktop, something is wrong. If that happens check to ensure the cables are properly connected.
  3. Once powered on, download, install, and then run the “RPiBoot.exe” program on your desktop PC. It will detect the CPi-xxxx panel PC and mount the eMMC as if it were an SD card (e.g. as a removable drive).
  4. Once the eMMC is mounted as a removable drive, follow the normal procedure for flashing or backing up an OS image.

See the Raspberry Pi eMMC Flashing Instructions for more information.

Creating an OS image from Scratch

We only support the OS images listed above, but for those who wish to understand how the ComfilePi OS images were created, or to assume the responsibility for creating and maintaining one's own operating system, the following details the procedure to provision an OS for the ComfilePi using the original Raspberry Pi Desktop OS as a base.

  1. Use the Raspberry Pi Imager to download and install the original Raspberry Pi OS image to and SD card or eMMC.
  2. Copy the following archive to the ComfilePi
  3. Run unzip, cd comfilepi, chmod +x, and the run ./ It will take a while to finish. Feel free to customize to your needs.
  4. Run cd .. and then rm -rf comfilepi to cleanup
  5. Reboot and enjoy!

Source Code

Source code for appropriately licensed software can be obtained by executing apt source {package_name} on the ComfilePi.
