[Xenomai-help] Problem with a serial test sofware

Hi,

I have a kernel 2.6.32.12 with Xenomai 2.5.3
I'm using a serial port with a PCMCIA card receiving a message each second
(9600 8N1) and I'm having some trouble with this software:
http://www.captain.at/xenomai-serial-port-example.php

$ dmesg | grep ttyS0
[   10.550153] 0.0: ttyS0 at I/O 0x5100 (irq = 10) is a 16550A
$ sudo setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x5100, IRQ: 10
$ sudo setserial /dev/ttyS0 uart none
$ sudo modprobe xeno_16550A io=0x5100 irq=10
$ sudo ./rt_serial_uprog
START RT_SERIAL
rt_serial_uprog: PRESS CTRL-C to EXIT
rt_serial_uprog: rtser_file opened
rt_serial_uprog: serial-port-config written
rt_serial_uprog: read-task created
rt_serial_uprog: starting read-task
read_task : error while RTSER_RTIOC_WAIT_EVENT, code -110
rt_serial_uprog: rtser0 (rtser) -> closed
read_task : exit

I don't receive any message...

$ lsmod
xeno_16550A            10568  0
serial_cs              20295  1
pcmcia                 34113  1 serial_cs
pcmcia_core            36724  4 serial_cs,pcmcia,yenta_socket,rsrc_nonstatic

Regards.

I do not know much about this test, so I will only have a stupid
question: is there anything sending messages to this machine through the
serial cable?

Yes there is.

Ok. And is the frequency sufficient for rt_serial_uprog ?

Please avoid using examples or docs from this site. It is seriously
outdated and is obviously no longer updated (the editor was informed
several times). I just recently had to support a local user because of a
documentation flaw of that site.

There is a serial example under xenomai/examples/rtdm/profiles/serial.

I didn't try the xeno_16550A with pcmcia so far, nor am I aware of any
successful attempt. Please check the code of the Linux driver. Maybe
there is some additional mapping of the 16550A registers required, or
they are organized in an incompatible way.
