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-150WR). For those models, simply open the file /boot/config.txt and edit the following line accordingly.

CPi-A070WR & CPi-A102WR

hdmi_cvt 800 480 60 6 0 0 0


hdmi_cvt 1024 768 60 6 0 0 0


hdmi_cvt 1024 600 60 6 0 0 0

Installation Instructions

The installation procedure is the same as that used with the Raspberry Pi 3. See “Writing an image to the SD card” at the Raspberry Pi Installation Instructions

Differences from Original Raspbian Distribution

COMFILE Technology maintains and distributes a custom Raspbian OS image for the ComfilePi products. It starts with the original Raspbian OS image, and then introduces the following changes:

  • Software that prohibits commercial usage is removed: This includes Mathematica and the Wolfram Language, the Oracle JDK, and RealVNC. A potential alternative to RealVNC is TightVNC. Any of these software packages can be reinstalled by running the appropriate sudo apt-get install {package-name} command.
  • The ComfilePi's Raspbian OS includes files at /opt/ComfileTech to support the following features:
  • Configuration changes necessary to support the ComfilePi's unique hardware (e.g. touchscreen, RTC, etc…).
  • The latest Mono Framework is installed for .Net developers.

Source Code

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