Hello, Im trying to get CEC work on an ODROID U2 with Arch Linux.
If I run in a terminal:
$this->bbcode_second_pass_code('', '# cec-client /dev/CEC')
This is the output:
$this->bbcode_second_pass_code('', 'No device type given. Using 'recording device'
CEC Parser created - libCEC version 2.1.3
opening a connection to the CEC adapter...
DEBUG: [ 3] unregistering all CEC clients
DEBUG: [ 3] Broadcast (F): osd name set to 'Broadcast'
ERROR: [ 3507] error opening serial port '/dev/CEC': Device or resource busy')
I installed linux from the image file of Arch Linux Web page: ArchLinuxARM-2013.07-odroid-u2.img
I'm thinking that maybe i've a problem with the libcec dependencies.
These are the dependences for libcec from libcec readme file:
$this->bbcode_second_pass_quote('', 'l')ibCEC needs the following dependencies in order to work correctly:
* udev v151 or later
* cdc-acm support compiled into the kernel or available as module
* liblockdev 1.0 or later

If I type #pacman -S udev
warning: systemd-204-3 is up to date -- reinstalling (that means udev is included in that package?)
I have found a packge (lockdev) but no liblockdev
$this->bbcode_second_pass_quote('', 'T')o compile libCEC on Linux, you'll need the following dependencies:
* autoconf 2.13 or later
* automake 1.11 or later
* libtool
* gcc 4.2 or later
* liblockdev 1.0 development headers
(I cant find a liblockde1-dev package as in raspbian repository)
$this->bbcode_second_pass_quote('', 'T')he following dependencies are recommended. Without them, the adapter can not
be auto-detected.
* pkg-config
* udev development headers v151 or later
(I cant find a libudev-dev package as in raspbian repository)
I get the source code for libcec from here:
http://odroid.us/mediawiki/index.php?title=HardwareAndDrivers
I'm usisng the Arch Linux Kernel(not the one sugested in odroid.us). And i followed these steps:
$this->bbcode_second_pass_code('', '#git clone --branch=exynos https://github.com/vamanea/libcec.git
#cd libcec
#./bootstrap
#./configure --enable-exynos')
when configure ends it shows:
$this->bbcode_second_pass_code('', 'libCEC version 2:1:0 configured
Compilation flags:
CXXFLAGS : -g -O2 -fPIC -Wall -Wextra -Wno-missing-field-initializers
libCEC LDFLAGS : -llockdev -ldl -lpthread -ludev
client LDFLAGS : -ldl -lpthread
Configured features:
Pulse-Eight CEC Adapter : yes
Pulse-Eight CEC Adapter detection : yes
Raspberry Pi support : no
TDA995x support : no
Exynos support : yes
You can now build libCEC by running:
make
')
Then I ran make and make install and everything seemed normal, despite the dependecies issue, commented earlier in this post.
I think that this kernel has support for CEC because when i run:
$this->bbcode_second_pass_code('', '# dmesg | grep cec
[ 0.170000] s5p_hdmi_cec_set_platdata()
[ 2.990000] s5p-cec s5p-cec: Probe start

[ 3.005000] s5p-cec s5p-cec: Requesting irq 146 for s5p-cec
[ 3.015000] s5p-cec s5p-cec: probe successful')
Tried to change the permisions of /dev/CEC, and also of /var/lock just in case
also check with$this->bbcode_second_pass_code('', '#fuser /dev/CEC') but there is no other procces using it.
Thank you. Best regards.
