Hi,
I've been attempting to get irda working on my Sony Vaio N505X (GB). I
*think* I do have it working, but so far I have seen no sign of life from
the only other ir device I have - an Ericsson DI27 irda modem on an
Ericsson T8s phone - which at least one person has reported as working with
linux irda (linked from linux irda web pages). I've tried all manner of
combinations of kernel + irda patch + irda utils right up to and including
the current ones, and read all that I could find on Linux irda (including
the archives), but no luck so far. I wonder if anyone can tell me if I'm
doing something wrong?
Whichever driver I use (irport/irtty+irattach) my ir device is not
discovered. The phone should look like a normal modem with irda
I am told. I have tried all the things that I know of - hopefully I'm
doing something stupid (:
Below, my attempts with various drives and my system config are shown. Please
skip it if it isn't interesting...
Many thanks, for Linux IRDA and for your (anticipated) comments.
Simon
-----------------------------------------------------------------------------
My system is Debian GNU/Linux 2.1 (slink) - kernel 2.2.14 with the SUSE
usb-2.3.28-for-2.2.13 USB backport and patch-2.2.14-irda1. Glibc is version
2.0.7 (19981211), and I'm currently using eiher 0.9.5 or 0.9.7 irda utils
(both seem to do the same for me). I also use pcmcia-cs Version 3.1.2.
>From my bios I know my irda port is at 0x3e8 irq 10, and Linux's serial
driver detects it with the wrong irq (so I simply setserial it correctly).
A friend with a PalmV ir-monitor program confirmed that even cat-ing to
the linux serial port produces IR output (before I had the irda patches):
cat foo > /dev/ttyS2
This gives a huge IR output from the port, and I use a mouse on ttyS0, so
I am sure I have the right serial device. In addition, my /proc/interrupts
shows the correct irqs in use if I fiddle with the two ports:
acronym:~# cat /proc/interrupts
CPU0
0: 33596 XT-PIC timer
1: 1909 XT-PIC keyboard
2: 0 XT-PIC cascade
4: 159 XT-PIC serial
5: 1 XT-PIC soundblaster
9: 312 XT-PIC uhci
10: 2 XT-PIC serial
12: 6129 XT-PIC PS/2 Mouse
13: 1 XT-PIC fpu
14: 5275 XT-PIC ide0
NMI: 0
Here are the three things I tried - only my attempts and results with the
latest irda stuff are shown - sorry about the long output!
(1) new nsc driver
==================
I think the Vaio is nsc: reading .inf files from windows seems to indicate
this.
acronym:~# rmmod serial
acronym:~# modprobe nsc_fir io=0x3e8 irq=10
Gives:
Jan 8 23:34:52 acronym kernel: nsc_fir_find_chip(), no chip at 0x150
Jan 8 23:34:52 acronym kernel: nsc_fir, Found NSC PC97338 chip, revision=2
Jan 8 23:34:52 acronym kernel: nsc_fir, Wrong chip version ff
Jan 8 23:34:52 acronym kernel: nsc_fir_find_chip(), no chip at 0x0ea
Jan 8 23:34:52 acronym kernel: nsc_fir_find_chip(), no chip at 0x15c
Jan 8 23:34:52 acronym kernel: nsc_fir_find_chip(), no chip at 0x02e
So I gave up on that for now.
(2) irport (without irattach):
==============================
I insert the correct modules and DO NOT use irattach:
acronym:~# modprobe irport io=0x3e8 irq=10
acronym:~# modprobe ircomm-tty
acronym:~# modprobe irlan
Now I have:
acronym:~# lsmod
Module Size Used by
irlan 35964 0 (unused)
ircomm-tty 28600 1
ircomm 12488 0 [ircomm-tty]
irport 6016 0 (unused)
irda 133361 0 [irlan ircomm-tty ircomm irport]
Now the ircomm0 device is registered in /proc/devices as:
161 ircomm
And setserial sees it:
acronym:~# setserial /dev/ircomm0
/dev/ircomm0, UART: 16550A, Port: 0x0000, IRQ: 0
I turn on discovery and debugging:
acronym:~# echo 1 > /proc/sys/net/irda/discovery
acronym:~# echo 1 > /proc/sys/net/irda/debug
I try to access the ircomm0 devicei, as nothing is discovered:
acronym:~# dip -t

(3) irtty with irattach:
========================
irattach is 0.9.7 (0.9.5 does the same)
I remove all irda modules from the previous test:
acronym:~# rmmod ircomm-tty
acronym:~# rmmod ircomm
acronym:~# rmmod irlan
acronym:~# rmmod irport
acronym:~# rmmod irda
I insert the serial module:
acronym:~# modprobe serial
I check/setup the serial ports:
acronym:~# setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
acronym:~# setserial /dev/ttyS2
/dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 4
acronym:~# setserial /dev/ttyS2 irq 10
acronym:~# setserial /dev/ttyS2
/dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 10
Insertion of irda modules:
acronym:~# modprobe ircomm-tty
acronym:~# modprobe irtty
acronym:~# modprobe irlan
Now I have:
acronym:~# lsmod
Module Size Used by
irlan 35964 0 (unused)
irtty 6880 0 (unused)
ircomm-tty 28600 0 (unused)
ircomm 12488 0 [ircomm-tty]
irda 133361 0 [irlan irtty ircomm-tty ircomm]
serial 18200 0
I switch debugging on:
acronym:~# echo 1 > /proc/sys/net/irda/debug
I start up irattach (NOT irmanager) in the recommended new way:
acronym:~# /home/simon/irda/irda-utils-0.9.7/irattach/irattach /dev/ttyS2 -s 1
1.1 Tue Nov 9 15:30:55 1999 Dag Brattli
The ircomm devices are now recognised:
acronym:~# setserial /dev/ircomm0
/dev/ircomm0, UART: 16550A, Port: 0x0000, IRQ: 0
I now test the device (as nothing is discovered):
