configs/broadcom_northstar: new defconfig
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.

Broadcom Northstar
|
||||
|
||||
Intro
|
||||
=====
|
||||
|
||||
This readme covers Northstar family of Broadcom SoCs. It includes:
|
||||
- BCM4708 (2 x 800 MHz)
|
||||
- BCM47081 (1 x 800 MHz)
|
||||
- BCM4709 (2 x 1 GHz)
|
||||
- BCM47094 (2 x 1 GHz) (AKA BCM4709C0)
|
||||
|
||||
Northstar platform is used in some home routers by multiple vendors. There are
|
||||
over 100 market devices based on it and they can all be supported with 1 kernel.
|
||||
|
||||
There is no point in having separated board for each model. This board code is
|
||||
meant for all supported Northstar devices.
|
||||
|
||||
All Northstar devices come with CFE bootloader by default. It's basically closed
|
||||
source as sources are available for some old releases only. There is no U-Boot (or
|
||||
any other) drop-in replacement or second stage loader with Northstar support.
|
||||
|
||||
CFE supports flashing firmware images over TFTP and HTTP (depending on vendor /
|
||||
device setup).
|
||||
|
||||
How to build it
|
||||
===============
|
||||
|
||||
$ make broadcom_ns_defconfig
|
||||
|
||||
$ make
|
||||
|
||||
How to flash over HTTP
|
||||
======================
|
||||
|
||||
Power on device and press (and hold) CTRL+C in serial console terminal. When CFE
|
||||
gets into prompt mode it'll automatically start built-in HTTP server. Navigate
|
||||
to http://192.168.1.1/ (unless IP was changed - verify with "ifconfig") and
|
||||
upload new firmware using a web browser.
