| 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_northstar_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. |
