h1. Linux on Auerswald COMmander Basic2

This page is an attempt to document bits and pieces about the embedded Linux OS that runs on the [[Auerswald COMmander Basic2]] PBX. 

More speificially, it's an ARM/Linux based system running on a "Digi International NS9360":http://ftp1.digi.com/support/documentation/91001326_D.pdf ARM926 SoC built from PTXdist-0.7.5
