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
h2. Source Code
* the PTXdist 0.7.5 source code can be found at https://public.pengutronix.de/software/ptxdist/v0.7/
* Auerswald has released _GPL tarballs_ at http://data-1.auerswald.de/license/gpl/COMfortel_VoIP_250_DECT1040_COMfortel2500/2015/GPL_COMfortel_VoIP_250_DECT1040_VoIP_2500_150415.iso
h2. Serial Console
The ARM SoC has a serial console (ttyS2) at 3.3V. It is running at 19200 bps and is exposed on test pads near the NS9630 on the PBX mainboard.
