irda with nc8000

someone uses irda with nc8000 laptop?

I have tried several times without success!
I don't know the chip that nc8000 haves for infrared so have tried all avaiable kernel modules ... but no way. ..

can someone help me?

kernel 2.6 on gentoo

Re: irda with nc8000

hi,

we have the same problem :) I found some relevant stuff on this page:
http://people.debian.org/~pxt/nc6000/

It doesn't work for me but at least something happens.


Oct 1 20:03:12 localhost toshsat1800-irdasetup: toshsat1800-irdasetup 0.2 2002/04/07 15:42 Daniele Peri
Oct 1 20:03:12 localhost toshsat1800-irdasetup: LPC47N227 chip (ver 0x5a, rev 0x0) found. Configuring:
Oct 1 20:03:12 localhost toshsat1800-irdasetup: set sirbase=0x3e8, firbase=0x130, dma=3, irq=7
Oct 1 20:03:12 localhost toshsat1800-irdasetup: set UART 2 IR mode to IrDA, auto powerdown on and powered up
Oct 1 20:03:12 localhost toshsat1800-irdasetup: LPC47N227 chip (ver 0x5a, rev 0x0) configuration successfully ended
Oct 1 20:03:12 localhost toshsat1800-irdasetup: PCI device 0x10b9:0x5a not found

if i say modprobe irda, modprobe smc-ircc it works well, but irattach says this:

Oct 1 20:04:36 localhost irattach: tcgetattr: Input/output error
Oct 1 20:04:36 localhost irattach: Stopping device /dev/ttyS2
Oct 1 20:04:36 localhost irattach: ioctl(SIOCGIFFLAGS): No such device
Oct 1 20:04:36 localhost irattach: ioctl: set_inidisc: Bad file descriptor
Oct 1 20:04:36 localhost irattach: tcsetattr: Input/output error
Oct 1 20:04:36 localhost irda: irattach startup succeeded
Oct 1 20:04:36 localhost irattach: exiting ...

What about you?

Re: irda with nc8000

hi Luca,
there was same question few days ago, try following:
I have different hw & sw ( acer travelmate 662 LCi and SuSE 9.1.) by maybe it's gonna be usefull for you.

sundance:~ # cat /etc/modules.conf
alias /dev/ircomm0 smc-ircc

my simple script for irda start:
#!/bin/bash
#arrangements for irda communication

setserial /dev/ttyS1 uart none port 0 irq 0
modprobe irda
modprobe nsc-ircc
irattach irda0 -s

and lsmod after this:

sundance:~ # lsmod | grep ir
nsc_ircc 15676 0
ircomm_tty 24072 0
ircomm 14212 1 ircomm_tty
irda 120124 3 nsc_ircc,ircomm_tty,ircomm


try these steps and post the result

Re: irda with nc8000

I use kernel version 2.6.8
for the following modules
nsc-ircc
w83977af_ir
smsc-ircc2
I get the same error : no such device.

for act200l-sir, dmesg say:

found SMC SuperIO Chip (devid=0x5a rev=00 base=0x004e): LPC47N227
smsc_superio_flat(): fir: 0x7d0, sir: 0x3e8, dma: 03, irq: 3, mode: 0x0e
smsc_ircc_present: can't get sir_base of 0x3e8

for other modules like stir4200 and actisys-sir with modprobe nothing happens.

lsmod
Module Size Used by
actisys_sir 2944 0
stir4200 14468 0
crc32 4608 1 stir4200
act200l_sir 3328 0
sir_dev 17324 2 actisys_sir,act200l_sir
irda 131388 4 actisys_sir,stir4200,act200l_sir,sir_dev
crc_ccitt 2432 1 irda

when I run irattach irda0 -s nothing happens.

thanks for the help!

Re: irda with nc8000

I must correct my last message:

found SMC SuperIO Chip (devid=0x5a rev=00 base=0x004e): LPC47N227
smsc_superio_flat(): fir: 0x7d0, sir: 0x3e8, dma: 03, irq: 3, mode: 0x0e
smsc_ircc_present: can't get sir_base of 0x3e8

is written from kernel after calling modprobe smsc-ircc2, and not act200l_sir.
it seems that a device is found with smsc-ircc2, but the parameters are wrong ?!

thanks again,

Luca

Re: irda with nc8000

Ahoy!

Success! :)))

1. Download tosh1800-smcinit and install from http://irda.sourceforge.net/smcinit/ (you will need pciutils-devel for this)
2. Install setserial if it is not installed
3. Edit your /etc/sysconfig/irda

IRDA=yes
DEVICE=irda0
#DEVICE=/dev/ttyS2
#DONGLE=actisys+
DISCOVERY=yes

4. add these lines to your modules.conf
install smsc-ircc2 /usr/local/sbin/tosh1800-smcinit -s 0x3e8 -f 0x130 -m 3 -i 7 -x 0x5a -c 0x4e; /sbin/modprobe --ignore-install smsc-ircc2
pre-install smc-ircc2 /bin/setserial "/dev/ttyS2" "uart" "none"
options smc-ircc2 ircc_fir=0x130 ircc_sir=0x3e8 ircc_irq=7 ircc_dma=3
alias irda0 smsc-ircc2
5. start irda

It seems to be working for me on a Mandrake 10.1 with 2.6.8.1-10mdk kernel.
