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 ARM926 SoC built from PTXdist-0.7.5

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

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.
