On what hardware does Xenomai run?
|
|
|
----------------------------------
|
|
|
|
|
|
Embedded hardware, desktop, server. This said, Xenomai has a strong
|
|
|
focus on embedded systems, and most Xenomai ports nowadays target
|
|
|
those platforms.
|
|
|
|
|
|
See the link:Embedded_Hardware[embedded hardware list], and the
|
|
|
link:Other_Hardware[other-hardware list].

Is my embedded setup supported by Xenomai?
|
|
|
------------------------------------------
|
|
|
|
|
|
See the link:Embedded_Hardware[embedded hardware list].

If your board is not listed above, you may want to get more information

from the mailto:xenomai@xenomai.org[Xenomai mailing list].

If you are willing to port Xenomai to an ARM-based system, you may
|
|
|
want to have a look at
|
|
|
link:Porting_Xenomai_To_A_New_Arm_Soc[this document].

What is this I-pipe thing? And what about Adeos? Are they related?
|
|
|
------------------------------------------------------------------
|
|
|
|
|
|
In Xenomai parlance, the I-pipe and Adeos both refer to the very same
|
|
|
code, that makes a Linux kernel able to host a secondary kernel
|
|
|
exhibiting real-time properties (e.g. Xenomai), on the same hardware.
|
|
|
|
|
|
This code is a kernel patch applied to a regular Linux kernel, which
|
|
|
among other services, guarantees delivery of external interrupts to
|
|
|
Xenomai with very low latency.
|
|
|
|
|
|
[NOTE]
|
|
|
You need the I-Pipe only for running Xenomai in a dual kernel
|
|
|
configuration, i.e. over the Cobalt core.
|
|
|
|
|
|
Which I-pipe patch should I use with Xenomai version X on platform Y?
|
|
|
---------------------------------------------------------------------
|
|
|
|
|
|
Check link:/downloads/ipipe/[there] for an I-pipe patch which best
|
|
|
fits your kernel.

What is a Xenomai _skin_?
|
|
|
-------------------------
|
|
|
|
|
|
To understand that, you should first know that Xenomai is some sort of
|
|
|
http://www.xenomai.org/documentation/slides/Xenomai-OSMB-2007-01.pdf[Chameleon
|
|
|
RTOS] at its core, which can export multiple real-time APIs to
|
|
|
applications, all built over the Xenomai _nucleus_.
|
|
|
|
|
|
A Xenomai API can impersonate an existing traditional RTOS interface
|
|
|
such as VxWorks (tm), or provide an original programming interface for
|
|
|
some particular purpose, such as
|
|
|
http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__rtdm.html[RTDM].
|
|
|
|
|
|
Basically, each API makes Xenomai look a different RTOS albeit all of
|
|
|
them are based on the same common core. This is the reason why we call
|
|
|
an implementation of such API, a Xenomai _skin_.
|
|
|
|
|
|
Can I still use GDB in a dual kernel configuration?
|
|
|
---------------------------------------------------
|
|
|
|
|
|
Yes, definitely. Debugging a Xenomai application in a dual kernel
|
|
|
system is no different from debugging any regular application.
|
|
|
|
|
|
[NOTE]
|
|
|
The only side-effect of using GDB for debugging a Xenomai application
|
|
|
is that breakpointing and single-stepping implies a switch to
|
|
|
secondary mode (i.e. threads are automatically handed over the Linux
|
|
|
kernel as soon as GDB regains control).

How to compile a RTDM-based driver?
|
|
|
-----------------------------------
|
|
|
|

See link:Building_Applications_For_Xenomai_3_X#compiling_a_rtdm_Based_module[there].

Running scripts/bootstrap complains about LT_SYS_SYMBOL_USCORE
|
|
|
--------------------------------------------------------------
|
|
|
|
|
|
e.g.:
|
|
|
..........................
|
|
|
$ cd xenomai-3
|
|
|
$ ./scripts/bootstrap
|
|
|
...
|
|
|
configure.ac:93: error: possibly undefined macro: LT_SYS_SYMBOL_USCORE
|
|
|
If this token and others are legitimate, please use m4_pattern_allow.
|
|
|
See the Autoconf documentation.
|
|
|
autoreconf: /usr/bin/autoconf failed with exit status: 1
|
|
|
..........................
|
|
|
|
|
|
On Debian-based systems like Ubuntu, you need to install the
|
|
|
libltdl-dev package for building Xenomai from sources.
|
|
|
|
|
|
Can I mirror Xenomai git repositories ?
|
|
|
---------------------------------------
|
|
|
|
|
|
Yes. However, we recommend using
|
|
|
link://github.com/mricon/grokmirror[grokmirror]. For more details, see
|
|
|
link:/mirroring-xenomai-git-repositories-with-grokmirror[the
