FreeBSD src
After several months of testing and fixing (and breaking) various parts of release/release.sh changes, it is now possible to build FreeBSD/arm images as part of the release process. When EMBEDDEDBUILD is set in the release.conf file, release.sh will create the build environment, then run a separate script in release/${XDEV}/release.sh [1]. Currently, only arm is supported. The release/${XDEV}/release.sh configures the build environment specific for the target image, such as installing gcc(1), installing additional third-party software from the ports tree, and fetching external sources. Once the build environment is set up, release/${XDEV}/release.sh runs Crochet, written by Tim Kientzle, which builds the userland and kernel, and creates an image that can be written to an SD card with dd(1). Many thanks to Tim for his work on Crochet. Sample configurations for FreeBSD/arm boards are in the release/arm/ directory, and Crochet configuration files for each board are located in release/tools/arm/. Supported boards at this time are: BEAGLEBONE, PANDABOARD, RPI-B, and WANDBOARD-QUAD. Adding support for additional boards will continue in the projects/release-embedded/ branch, and incrementally merged back to head/. Many thanks to the FreeBSD Foundation for the support and sponsorship of this project. [1] XDEV is used in order to keep the various configurations organized by architecture, but since TARGET and TARGET_ARCH are used to build the chroot, the values of those variables cannot be used.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
