[Xenomai-help] Test xen_16500A.ko on different serial port

Hi

I start with xenomai so I patch the kernel 2.6.26.7 with the version 2.4.6.

So I try to test the xeno_16550A.ko driver generated instead of the standard
16550A on serial port ttyS0 ioaddr=0x3f8 irq=4 (standard one) and also on
serial port in PCI card ttyS6 ioaddr=0xe0000400 irq=10.

I used the following command to substitute the 16550A driver used by the
xeno_16550A.ko:

> setserial /dev/ttyS0 uart none
> insmod ./xeno_16550.ko ioaddr=0x3f8 irq=4

I got the error message :

xeno_16550A: Unkonwn parameter 'ioaddr'
insmod: error inserting './xeno_16550A.ko': -1 Unknown symbol in module

and I got the same thing with the other port.

Can you explain me how I can load correctly the xeno_16550A.ko

Thanks for your help.

Marcel.

There is no ioaddr parameter to this module, as documented here:
http://www.xenomai.org/index.php/16550A

The "Unknown symbol in module" message alone does not tell us much,
module related message appear clearly in the kernel logs, not on the
terminal where modprobe is run.

Instead of 'ioaddr', try 'io' (without the apostrophes)

You may try "io="

Hi,

thanks for the answer.

now, the command insmod ./xeno_16550.ko io=0x3f8 irq=4 is accepted.
My question is: does the xeno_16550A.ko driver has replaced the 16550A and I
able to use the serial com as usual ?

Because I try to communication but it doesn't work.

thanks,
Marcel.

Hi sorry,

I was not very explicit in my last mail.

I try to test with the code from
http://www.captain.at/xenomai-serial-port-example.php

but i got an error: "can't open rtser6" because i try to communicate with
the port "ttyS6"

Do I load something related with the RTDM or something else ? I'm a bit
confused.

thanks,
Marcel.

The enumeration of the Xenomai serial driver has nothing to do with the 
Linux counterpart. Try rtser0. Also note that you have to use the RT 
serial driver through RTDM calls and not Linux system calls.
