Broadcom Northstar family of SoCs is most commonly used for home routers. It's an ARM platform with Cortex-A9 CPU(s). All known Northstar devices come with CFE bootloader which almost always expects a TRX firmware format (with exception for D-Link). Some vendors (like Luxul and Netgear) wrap TRX in their own containers. This board code provides: 1. Minimal kernel with support for on-SoC blocks. It enables Linux drivers for SoC, watchdog, Ethernet, switch, USB, PCIe, LEDs). 2. Post image script building firmware images. In uses Buildroot packages tools (lzma_alone, otrx, lxlfw) to build bootloader-compatible images that can be flashed.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
