CEC on Wandboard Quad

[Rene]

Hello everyone,

first of all, i really appreciate your work Stephan. Your Yocto XBMC images worked fine for me so far. I replaced my Raspberry Pi, which i used a couple of years for streaming TV from my SAT-Receiver, with a Wandboard Quad. It’s really fast and HD live-streams are no problem anymore. Thank you very much!

Now i have a Wandboard Quad Rev C1 which should be able to handle CEC over it’s HDMI port. I checked out your latest Revision from the dora tree of your git-repository and made a new image. Unfortunately CEC is not working for me. I know there is a rough explanation on how to get CEC working in XBMC over at but compiling a kernel and patching the libcec is quite complicated for someone who is not familiar with this stuff.

So my question: is there a pre-build yocto/XBMC image with CEC support available? Or a repository where i can just bitbake a working image from?
If not, does anyone have some hints for me on how to set up the kernel build environment and how to patch the libCEC?

Any help would be appreciated.

Hi Rene

Thanks a lot for your post,
I think the following wandboard quad build has CEC working out of the box (it also packages a recent 13.1 xbmc build) :

Please give it a try and tell me if it is not the case..

Kind regards
Stéphan

Hello Stéphan,

thank you for the image. Unfortunately CEC is still not working for me. I am using a LG TV where CEC worked with RasperryPi/Openelec. When i grep cec in xbmc.log i get:

19:50:13 T:739569664  NOTICE: Register - new cec device registered on cec->i.MX: CEC Adapter (0471:1001)
19:50:13 T:1021310032  NOTICE: Thread CECAdapter start, auto delete: false
19:50:13 T:1031795792  NOTICE: Thread PeripBusCEC start, auto delete: false

19:50:14 T:1099953232   ERROR: CecLogMessage - Write: sent command error !

So i guess the Wandboard wants to enable CEC but my TV just doesn’t see it.

With your prebuild image i also have asynchronous audio/video during live HD streams. Didn’t have this issue with images build from your github.

Do you have any further advice? Else i will skip CEC and use a wireless keyboard.

Thanks a lot!
Rene

Can you provide an alternative link to your latest builds? Somehow your blog is extremely slow and I can’t download the build. Thanks.

well,
i’ve now added the hardware hack to my wandboard, to enable cec.
is there an actual image that i can use to run xbmc with cec support on the wandboard or must i build my own?

the tv that i want to connect is a samsung

Hi,

I would advise to give a try at archlinux arm : http://archlinuxarm.org/platforms/armv7/freescale/wandboard
They have packaged all my work related to CEC and it should be all good…

Stéphan
