OEM easy installation

FIXME The instructions below are for Broadcom devices and only serve as an example. Don't leave them in place if they do not apply to a particular device!

This section deals with how you install OpenWrt from a device freshly opened. Plus the steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

OEM installation using the TFTP method

If you want to upgrade using TFTP you follow these steps (as an alternative to the above install process.

Upgrading OpenWrt


If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

Hardware mods

  1. as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!


The board boots with the files: openwrt-ap1000-zImage and openwrt-ixp4xx-generic-squashfs.img, but due to the lack of patches for it, is not stable. The kernel image must be recorded in mtd3 labelled kernel and squashfs or jffs2 image in mtd4 labelled image.

The serial port at bootup is TTYS1.
