tuto mandrake 10.1 and Lirc serial

[Guest nethy]

I am looking for a tuto to implement lirc (serial) on a mandrake 10.1.

I have read a quite simple tuto done by aRTee (thanks you) but it was not for lirc_serial_home

 

http://www.mandrake.tips.4.free.fr/configuration101.html

 

could someone help me to implement lirc serial on my mandrake 10.1 (i am a newbies)

 

thanks

You can always compile it yourself: http://mandrakeusers.org/index.php?showtopic=19428

 

Just change the configuration bit and load the correct module.

 

Good luck.

[aRTee]

The kernel recompile is probably not necessary.

 

In the normal Mandrake kernel, the modules fail to get compiled.

In the configuration the lirc code is selected to be compiled as modules. But they don't get compiled, due to some bug.

 

I have compiled them myself, by taking the code from the mandrake 2.6.7 multimedia kernel, sticking that into the kernel source tree in place of the original non compiling lirc code, and compiled the modules.

 

See also the bugreport:

http://qa.mandrakesoft.com/show_bug.cgi?id=10826

 

 

You will find those modules at the aforementioned link, including the lirc_serial_home.ko module.

 

 

To the topic starter, have you taken the necessary modules, ran

depmod -a

after placing them?

 

What else have you tried?

And how did the system respond?

i try that but when i check if lirc serial is responding : mode2 the answer is " This program is only intended for receivers supporting the pulse/space layer.

Note that this is no error, but this program simply makes no sense for your

receiver."

 

just to make a recap i do this to my config

 

1) i change /etc/sysconfig/lircd :

DRIVER=default

 

# Hardware driver module to load

#HWMOD=lirc_dev

#HWMOD=lirc_i2c

HWMOD=lirc_serial

 

# The device node that communicates with the IR device.

# if you are using lirc_serial, set DEVICE to /dev/ttyS[0-9]

# where 0-9 is the serial port your IR receiver is plugged

 

# with devfs enabled

#DEVICE=/dev/lirc/0

DEVICE=/dev/lirc/serial

 

# without devfs

#DEVICE=/dev/lirc

 

# Serial port for the receiver (for serial driver)

# COM1 (/dev/ttyS0)

COM_PORT=/dev/ttyS0

DRIVER_OPTS="irq=4 io=0x3f8"

 

# COM2 (/dev/ttyS1)

#COM_PORT=/dev/ttyS1

#DRIVER_OPTS="irq=3 io=0x2f8"

 

2) i creted a directory with missing files

 

mkdir -p /lib/modules/2.6.8.1-12mdk/kernel/3rdparty/lirc

 

3) i put your files (found at http://www.mandrake.tips.4.free.fr/lib/mod...3rdparty/lirc/)

 

4) and do :

depmod -a

mknod /dev/lirc/0 c 61 0

service lircd start

service lircmd start

 

service start ok but when i check if it working (going into mode2) it seems to doesnt working

 

have you an idea?

 

Thanks

[aRTee]

Ok, first, you have to put lirc_serial_home instead of lirc_serial into /etc/sysconfig/lircd

 

second, I don't think that for you you need to make mknod /dev/lirc/0 c 61 0, but even so, you are referring to DEVICE=/dev/lirc/serial - this reference must be to the lirc device.

 

You only have to do the depmod -a once (to let the kernel know there are new or changed modules).

 

What happens if you do:

modprobe lirc_serial_home

?

 

Check if any device node is created at /dev/lirc

ll /dev/lirc*

 

Another issue: the lircd file is wrong, use this one instead (substitute your /etc/rc.d/init.d/lircd with this code):

 

#!/bin/sh

           exit 1
          ;;

exit ${RETVAL}

 

 

If all goes well you should be able to do

service lircd start

service lircmd start

i try and when i do

 

modprobe lirc_serial_home i get

 

WARNING: Error inserting lirc_dev (/lib/modules/2.6.8.1-12mdk/kernel/3rdparty/lirc/lirc_dev.ko): Invalid module format

i check for node

[aRTee]

Make sure you're using the modules from here:

http://www.mandrake.tips.4.free.fr/lib/mod.../3rdparty/lirc/

 

and not those from the 10.1CE kernel.

 

If you're not sure, do

modinfo lirc_dev

or

modinfo lirc_serial_home

to find out which ones you have.

 

vermagic should correspond with your kernel.

Do

uname -r

to find out which kernel you're running.

 

 

Hope this helps.

[Guest nethy]

you was right i was using bad file version.

 

I remplace every files by right one.

 

now when i do modinfo lirc_dev

filename: /lib/modules/2.6.8.1-12mdk/kernel/3rdparty/lirc/lirc_dev.ko

description: LIRC base driver module

author: Artur Lipowski

license: GPL

vermagic: 2.6.8.1-12mdk 686 gcc-3.4

depends:

 

but i still get

 

depmod -a

[root@vdr /]# modprobe lirc_serial_home

FATAL: Error inserting lirc_serial_home (/lib/modules/2.6.8.1-12mdk/kernel/3rdparty/lirc/lirc_serial_home.ko): Device or resource busy

[aRTee]

What does lsmod say about any lirc module? Are they really in use?

 

Try

rmmod [modulename]

to unload them, then reload with modprobe.

[aRTee]

Hmm, reading back I think the problem may be that you created the node by hand on the wrong name -- well, wrong for your module; you followed my instructions for a different device/driver.

 

If

ls -l /dev/lirc

shows

crw-r--r-- 1 root root 61, 0 Nov 8 19:31 0

(with likely a different date), it means that there is a /dev/lirc/0 device, with node numbers 61, 0, but not as it is supposed at /dev/lirc/serial or maybe by now /dev/lirc/serial_home.

 

If my assumptions are correct that this file exists because you made it, and this is blocking, then you have to remove the node, with a

rm

command.

 

I hope this is the problem, that's the only thing I've been able to come up with..
