Post subject:  Upgrading to R5F1 - irblaster won't work
under R5C7, I had my irblaster working great. Getting it to work post-upgrade is proving to be a real challenge.

I've gone over everything that I can squeek out of Greg Frost's tread..
http://mysettopbox.tv/phpBB2/viewtopic.php?t=9352

when I execute
Code:
/etc/init.d/irblaster start

I get the message
Quote:

I'm guessing that my symbolic links are screwed up.. but I've run out of ideas on how to fix it.

Thanks!

Here's my /etc/irblaster/hardware.conf

Code:
# /etc/irblaster/hardware.conf
#
#  Author: Greg Frost

# The COM Port used by the IRBlaster. Set it to COM1 COM2 or "".
IRBLASTER_SERIAL_PORT="COM1"

# Set this to the lirc device that will be used by lirc_serial. In my case
# it is /dev/lirc. I have a USB remote, so my remote does not use the
# /dev/lirc device, so it is used by lirc_serial for my ir blaster. If you
# have a remote that uses /dev/lirc, the blaster may user /dev/lirc1. Not
# sure.

IRBLASTER_DEVICE="/dev/lirc1"

Why didn't you go to R5F27 which has been out since Sunday?

What can I say, my psychic interface isn't working. .. I started the upgrade to R5F1 on 09/04. I'm tempted to charge-along with the R5F27 upgrade, although, I would like to understand why the irblaster isn't working first... and get it working.

If you read the hints and tips you would have seen something about the possibility of xorg grabbing the serial port for a serial mouse. dont know if this is your problem, but I didn't see you see that you had checked it.

Right! I didn't make the connection. Now done.. X restarted. restarting irblaster comes up with the same error. I'll have to admit, when it comes to the /dev directory, I'm in the fog. Here's what it looks like:
Code:
ls -l /dev/ttyS*
crw-rw---- 1 root dialout 4, 64 Sep 13 19:21 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 Sep 13 19:21 /dev/ttyS1
crw-rw---- 1 root dialout 4, 66 Sep 13 19:21 /dev/ttyS2
crw-rw---- 1 root dialout 4, 67 Sep 13 19:21 /dev/ttyS3
and
Code:
ls -l /dev/lirc*
crw-rw---- 1 root video 61, 0 Sep 13 19:21 /dev/lirc0
srw-rw-rw- 1 root root      0 Sep 13 19:21 /dev/lircd

I re-ran the irblaster.sh config script and it gives me
Code:
Selected Motorola_DCT2244.
cp: cannot stat `/usr/local/share/knoppmyth/irblaster/Motorola_DCT2244/irblasterd.conf': No such file or directory

I can't speak for R5F1 but this file is called /usr/local/share/knoppmyth/irblaster/Motorola_DCT2244/irblaster.conf (no d) in R5F27. I suspect this error is the crux of your problem.

You could A) try copying /usr/local/share/knoppmyth/irblaster/Motorola_DCT2244/irblasterd.conf to /usr/local/share/knoppmyth/irblaster/Motorola_DCT2244/irblaster.conf or B) edit the irblaster.sh script to point to the correct file.

I did Plan A .. and got:

Shorter error message! :D
Then I deleted the files in /etc/irblaster, re-ran the irblaster.sh script and got
Code:
Selected Motorola_DCT2244.
 System startup links for /etc/init.d/irblaster already exist.

.. so I'm thinking that "System startup links" is the key??? Is that what the "update-rc.d" is about??? .. so I ran
Code:
update-rc.d -f irblaster remove
then re-ran the irblaster.sh script again.. and got:
Code:

Looks like were getting.... I'm still leaning toward something that's dorked in the device setup (fogged).

This is the killer.
Why can't it insert the lirc_serial module?
Are your serial ports enabled in the bios?
Something else using the serial port?
lirc_serial already loaded?

(1) Why can't it insert the lirc_serial module?
(2) Are your serial ports enabled in the bios?
(3) Something else using the serial port?
(4) lirc_serial already loaded?

(1) I dunno how that works
(2) sure
(3) There shouldn't be! how can I tell?
(4) if so, can I unload it, then run irblaster.sh again? (how would I unload it?)

I have an hd with R5C7 .. a backup of my primary system (the primary having been upgraded to R5F1) .. if I shutdoen/swap drives/restart.. the irblaster works. I'll concluded that there is no bios setting wrong or hardware issue.

I'm not sure what would cause that Input/Output error.
To see if the module is loaded, run the command (as root)
Code:
lsmod | grep lirc

If it is not, try running:
modprobe lirc_serial
what happens? are there any suspicious error messages in /var/log/messages?
What is in the file /etc/mythtv/modules/lirc_serial?
What type of remote does your system use?

I did solve this issue by running "Auto Upgrade" to R5F27.
Keep in mind the important locations for configuration bits:
/etc/irblaster/hardware.conf
/etc/irblaster/irblasterd.conf
/etc/irblaster/channel_change.sh
/etc/init.d/irblaster
/dev/irblasterd
