i have hacked my wandboard using the following link:

running cec-client and xbmc cec-adapter at the same time is not possible.
As you say, that cec-client is finding your device, it seems you correctly soldered the "cec-pipe-hack".
For me your problems seems software/driver related.

by **kohonen** » Tue Mar 04, 2014 1:18 pm

i know, i am 99% sure it is not a hardware problem, but how do i fix it? :mrgreen:

by **setti** » Tue Mar 04, 2014 1:43 pm

your cec messages are nearly identical to mine.
So you could remote your tv using cec-client. for instance by sending "standby 0" or "on 0" to turn off/on your tv.
Are you running xbmc via service? It could be you are missing some udev rules, to let the xbmc user write to cec.

Im having some more udev rules on my system.

Code: Select all: root@wandboard:/ # cat /etc/udev/rules.d/99-input.rules KERNEL=="event*", SUBSYSTEM=="input", GROUP="tty", MODE="0660" SUBSYSTEM=="tty", KERNEL=="tty[0-9]*", GROUP="tty", MODE="0660" root@wandboard:/ # cat /etc/udev/rules.d/99-hdmi-cec.rules KERNEL=="mxc_hdmi", SUBSYSTEM=="mxc_hdmi", GROUP="video", MODE="0666" KERNEL=="mxc_hdmi_cec", SUBSYSTEM=="mxc_hdmi_cec", GROUP="video", MODE="0666" root@wandboard:/ # id xbmc uid=1000(xbmc) gid=1000(xbmc) Gruppen=1000(xbmc),5(tty),6(disk),10(wheel),90(network),91(video),92(audio),93(optical),95(storage),98(power)

you could try to figure out, if it is udev related, by running xbmc via root in foreground.

Could you please tell me if, you have trouble getting cec up and running on after restarting your tv, while xbmc is running. im having an issue, that the cec-adapter is not found anymore after tv restarts.

by **kohonen** » Tue Mar 04, 2014 2:13 pm

problem is, cec-client doesn't react to the remote control, you are supposed to see some messages when pressing buttons on the remote

Code: Select all: [root@alarm /]# cat /etc/udev/rules.d/99-input.rules KERNEL=="event*", SUBSYSTEM=="input", GROUP="tty", MODE="0660" SUBSYSTEM=="tty", KERNEL=="tty[0-9]*", GROUP="tty", MODE="0660" [root@alarm /]# id xbmc uid=1001(xbmc) gid=1001(xbmc) groups=1001(xbmc),6(disk),90(network),91(video),92(audio),93(optical),95(storage),98(power)

we have almost the same output, BUT i don't have the 99-hdmi-cec.rules file :geek:

i will try it after i get home, thanks for a hint!

by **setti** » Tue Mar 04, 2014 2:40 pm

your udev rule doesnt do anything for user xbmc, since your xbmc user isnt in group tty.

try

Code: Select all: usermod -G tty -a xbmc

by **kohonen** » Tue Mar 04, 2014 2:43 pm

yeah, that's clear, but i am running the cec-client under root. anyway, i will try and let you know later today (tonight?)

by **kohonen** » Tue Mar 04, 2014 7:17 pm

it did help, thanks a lot!

by **setti** » Tue Mar 04, 2014 7:41 pm

nice to hear that.
could you please try the following:
stop xbmc
start TV
start cec-client
stop tv
start tv
enter the following inside cec-client session: standby 0

in other words, is your cec-client detecting the restart of the TV? Im Not sure if im having a software or hardware Problem....

by **kohonen** » Tue Mar 04, 2014 8:17 pm

cec-client doesn't seem to be working very good for me, i have stopped xbmc, but it is not even reacting to remote key presses. i have a LG TV and when running xbmc, TV shows "HDD recorder" as the simplink source, don't know if it's ok.
