[irda-users] can't get irda to work on a TECRA M1

[Louis-Benoit J. <th...@gm...>]

Hi,

I'm using:
>uname -a
Linux louve 2.6.9-gentoo-r1 #7 Fri Nov 18 15:02:07 CET 2005 i686
Intel(R) Pentium(R) M processor 1400MHz GenuineIntel GNU/Linux

in modules.conf, I have:
alias irda0 smsc_ircc2

I run the following commands in this order:
- smcinit -v -f 0x0130 -s 0x2f8 -d1 -i3
- modprobe smsc_ircc2

That loads the driver correctly:
Dec 21 11:37:00 louve kernel: NET: Registered protocol family 23
Dec 21 11:37:00 louve kernel: found SMC SuperIO Chip (devid=3D0x5a
rev=3D00 base=3D0x002e): LPC47N227
Dec 21 11:37:00 louve kernel: smsc_superio_flat(): fir: 0x130, sir:

Dec 21 11:37:00 louve kernel: SMsC IrDA Controller found
Dec 21 11:37:00 louve kernel:  IrCC version 2.0, firport 0x130,

Dec 21 11:37:00 louve kernel: No transceiver found. Defaulting to Fast
pin select
Dec 21 11:37:00 louve kernel: IrDA: Registered device irda0

And I can see the interface is configured:
>/sbin/ifconfig irda0
irda0     Link encap:IrLAP  HWaddr 65:64:08:04
         NOARP  MTU:2048  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:8
         RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
         Interrupt:3 Base address:0x130

Now, I irattach irda0:
Dec 21 11:38:56 louve irattach: executing: '/sbin/modprobe irda0'
Dec 21 11:38:56 louve irattach: executing: 'echo louve >
/proc/sys/net/irda/devname'
Dec 21 11:38:56 louve irattach: executing: 'echo 1 >
/proc/sys/net/irda/discovery'
Dec 21 11:38:56 louve irattach: Starting device irda0

I can see the interface is up:
>/sbin/ifconfig irda0
irda0     Link encap:IrLAP  HWaddr 65:64:08:04
         UP RUNNING NOARP  MTU:2048  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:8
         RX bytes:0 (0.0 b)  TX bytes:30 (30.0 b)
         Interrupt:3 Base address:0x130

setserial says:
>setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
>setserial /dev/ttyS1
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3

But, irdadump reports nothing. It looks like it's not configured properly.
I put my phone in front of the irda receiver, nothing is being filtered.

Should irdadump report something?

Then, I load the drivers for ircomm_tty (in modules.conf, I have:
alias tty-ldisc-11 irtty
alias char-major-161 ircomm_tty)

and I try to sync my pilot by irda on /dev/ircomm0, it doesn't work.

The smcinit page says the sir port is supposed to be on 0x3f8.
Whenever I configure the port with smcinit to 0x3f8 and then I try to
load the module smsc_ircc2, it fails with:
Dec 21 11:23:09 louve kernel: NET: Registered protocol family 23
Dec 21 11:23:09 louve kernel: found SMC SuperIO Chip (devid=3D0x5a
rev=3D00 base=3D0x002e): LPC47N227
Dec 21 11:23:09 louve kernel: smsc_superio_flat(): fir: 0x130, sir:
0x3f8, dma: 01, irq: 3, mode: 0x8a
Dec 21 11:23:09 louve kernel: smsc_ircc_present: can't get sir_base of 0x3f=
8

So I think my ports are good.

Any idea what is going wrong with my settings?

Thanks a lot in advance,

LB
