First off, remember that by following these instructions you may brick your CBC and void your warranty. Also, this version of the code only works on the CBC 2. You have been warned.

To build the CBC Firmware, You'll first need to have a Linux system up and running, preferrably Ubuntu 9.10. You'll also need to install the following pieces of software by hand:

• build-essentials
• ARM GCC Toolchain
• Qt Embedded 4.5

As well as the following minor pieces of software (easily installed through your distro's package manager) many of the following are installed from (sudo apt-get install build-essentials)

• GCC
• GNU Make
• Qt 4.7
• Rsync
• Wget

Instructions for downloading and installing the ARM GCC Toolchain necessary to build this software can found here. GCC 4.3.2 is required for this to work on your CBC.

Instructions for building Qt Embedded can be found here. It is only necessary to follow the instructions until the installation of Qt is finished. There's some useful info there though :)

The Userhook0 version format follows the format... Major Minor Build X . Y . Z

Major = System wide changes for the CBC. (New Vision, Library, etc...) Minor = Added new features. (New calibration page, buttons, graphics...) Build = Bug fixes and changes to default settings (flags, calibration settings, debug...)

Building the software is simple:

cd cbc
make

You should now have a CBC_interface file in filesystem/upgrade. Happy Hacking!
