CPU for the CoDeSys Linux Runtime:

The processors x86, ARM and PowerPC are supported.

CoDeSys V3Overview Linux

CoDeSys V3 Linux Runtime Overview

Linux without Realtime:

Linux with Realtime:

Memory Requirements:

Basically any distribution can be used. A customizedLinux is necessary for embedded systems. Additionallibraries for example for PCI bus support or PCAP forEthernet are also required. All libraries are open source.

CoDeSys V3 under Linux with realtime properties canonly be used with the realtime kernel Preempt_rt patchfrom the OSADL organisation. RT Linux, RTAI Linux andXenomai are not supported!The OSADL realime kernel is free of charge but it mustbe adapted to the particular hardware. Such an adaptionis offered for example by Linutronix, Pengutronix or Denx.

3S-Smart Software Solutions GmbH does not offersaid adaptation service! Before starting a project thehardware to be used should be considered suitableby the company who is to perform the adaptation!

Important for CoDeSys: There must be adebugger!Debugger for ARM or PowerPC over GDB Server withthread-support!Debugging on the x86 platform is normally no problem.

Linux From Scratch (LFS) is a project that provides you withstep-by-step instructions for building your own customLinux system, entirely from source code:

What is the best way to build a Linux distribution for anembedded system in a reproducable way,caring aboutlong term maintenance and small footprint? PTXdist is aGPL licensed build system for userlands, started byPengutronix. It uses the Kconfig configuration systemfrom the Linux kernel. Although PTXdist (without patches)still fits on one disc, a whole root filesystem can be builtas easy as "ptxdist go":
