[Xenomai-help] xenomai beginner problem.

[Kim Chuan Lim]

Hi all,
The following is my problem...

suse003:/usr/xenomai/testsuite/latency # ./run
*
*
* Type ^C to stop this application.
*
*
Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled.
(modprobe xeno_native?)
suse003:/usr/xenomai/testsuite/latency # modprobe xeno_native
FATAL: Module xeno_native not found.

i'm using an old pentium 3 1GHz machine with suse9.3.
i recently downloaded kernel 2.6.17 from kernel.org and patch it with
xenomai trunk.

May i know what is my problem??
Is it i didnt setup my kernel probably?

The following is the result of my locate..

locate xeno_native
/home/username/linux-2.6.17.4/kernel/xenomai/skins/native/.xeno_native.o.cmd
/home/username/linux-2.6.17.4/kernel/xenomai/skins/native/xeno_native.o

How can i load the xeno_native manually?

Regards,
Kim Chuan.

This may mean two things:
- either you did not compile the native skin as a module, it is
  built-in, and as suggested by the error message
  you disabled CONFIG_XENO_OPT_PERVASIVE in the "real-time subsystem"
  menu of the kernel configuration menu;
- or the compilation of the xeno_native module (and linux kernel) failed.

In order to conclude, posting /home/username/linux-2.6.17.4/.config as
well as the build logs if compilation failed, may help.

xeno_nucleus and xeno_native are by default both compiled into your
kernel. Therefore: no modules.

What does dmesg tell you regarding Xenomai? Any suspicious
warnings/errors? I'm thinking now of the issue that local APIC is
enabled in the kernel, but "lapic" is missing in the kernel command
line. The kernel messages should indicate this.

Check you kernel configuration if this is really needed - I bet not.

Hi Jan,

You are right, i got some informations from my dmesg...
Xenomai: Local APIC absent or disabled!
         Disable APIC support or pass "lapic=1" as bootparam.
Xenomai: system init failed, code -19.
Xenomai: native skin init failed, code -19.
Xenomai: starting POSIX services.
Xenomai: POSIX skin init failed, code -19.
Xenomai: RTDM skin init failed, code -19.

The following is part of my APIC kernel configuration.

# CONFIG_HPET_TIMER is not set
CONFIG_PREEMPT_NONE=y
# CONFIG_PREEMPT_VOLUNTARY is not set
# CONFIG_PREEMPT is not set
CONFIG_IPIPE=y
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y
CONFIG_X86_MCE=y

What should i do??

Kim Chuan.

Try passing "lapic=1" as kernel boot parameter, and if it still does not
work, recompile your kernel with APIC support disabled.

If you want to know more about this issue, read the TROUBLESHOOTING

Thanks. It works.

I try to run some examples programs at /usr/xenomai/testsuite/latency/run ..
the following is the error i received..
warming up...
latency: failed to set periodic, code -110

Any quick suggest?

Disable CONFIG_CPU_FREQ. If things don't improve, disable CONFIG_ACPI
globally to see if this works. Make sure CONFIG_PM is disabled too.

[Kim Chuan Lim]

Hi Philippe,

Thanks, it works again. ^ ^

I manage to run few testsuit program but two of them(switchbench and
cyclic) are crashing my xenomai machine.

May i know what is the reason?

Kim Chuan.

The reason is unknown so far, such crashes are abnormal. What kind of
crash is it ? Also, if not running in text mode, could you run the tests
in text mode, in order to be able to send us the kernel oops text or
stack trace, if any.

Further things that may help to track this down:

o Was your kernel build and installation really consistent after the
  last modifications, did you re-run both module_install _and_ install?

o Which tests succeeded? Maybe the effect is limited to one skin (for
  what reason ever).

o Please do not forget to attach your .config (preferably compressed).
  You were using latest SVN trunk of Xenomai?

o If you face a total hang up of your box, try to redirect the kernel
  messages to a serial console and capture the result via a null-modem
  link to a second station. See linux/Documentation/serial-console.txt
  for a howto.

Thanks in advance,
Jan

Hi all,

Please find the attachment for my linux kernel config.
Please let me know if anything wrong in the configuration.

Nothing suspicious on first sight. Please proceed with Gilles' and my
other suggestions now.

Re: [Xenomai-help] xenomai beginner problem.

[Kim Chuan Lim]

Hi all,

I managed to install Xenomai into another of my machine.
I am able to run all the test program without any problem.

I am interested with the hard real time serial port example from..
http://www.captain.at/xenomai-serial-port-example.php

The following is the error message i received when i try to run the program..
./rt_serial_uprog
rt_serial_uprog: PRESS CTRL-C to EXIT
rt_serial_uprog: timer started
rt_serial_uprog: can't open rtser0
rt_serial_uprog: stop timer

May i know which device is "rtser0"?
shall i just change it to /dev/ttyS0?

Regards,
Kim Chuan.

Hmm, while it's nice to hear that this works, there remains the
uncomfortable feeling that something might be broken on your first box.
When time allows, we would welcome further investigations, specifically
a capture of that infamous oops.

Check Hannes' doku: you have to load the xeno_16550A driver.

I'm also a beginner on Xenomai and I have the same problem as Kim Chuan Lim.
 I verified my configuration : RTDM skin and 16550A driver are both integrated 
in my 2.6.16 kernel, so these modules don't exist.
Shall I create rtser0 node ?

Nope, there is no such thing as device nodes under Xenomai's RTDM skin.
But when your 16550A driver is compiled into the kernel, you have to
provide some hardware parameters via the boot command line to configure
at least one port:

8250.nr_uarts=0		(to keep Linux away from using the UARTs)
xeno_16550A.ioaddr=0x3f8 (first UART)
xeno_16550A.irq=4	(first UART)

Of course, you can also increase 8250.nr_uarts and move the 16550A
driver to some other port etc. I guess this should make it into
doc/txt/16550A-driver.txt as well...

Alternatively, turning xeno_16550A into a module again allows you to
reconfigure your hardware on a running system. Then that mentioned doc
file fully applies again.

I think I had the 16550A driver once also compiled in, but I couldn't configure
it. But once you compile it as module, check:
http://www.captain.at/xenomai-xeno_16550A.php

Hannes.
