[SOLVED] HDMI CEC on odroid XU4

Unread postby kiloupyn » Thu Mar 17, 2016 4:37 am

Hello,

I would like to know if the odroid XU4 board works with the HDMI-CEC linux library (libcec). My TV brand is Samsung.

Anyone got experience with it ?

Best Regards,
PY

We tested Samsung Anynet+ with Kodi on Ubuntu and Android.
It worked.

I'm not having luck with my Samsung 1080p TV and my XU4 (64G eMMC) on Ubuntu 15.10 either.
The resolution does not change regardless of my changes to the boot.ini video settings (simply un-commenting any setenv line, CEC or not). Even 720i/p settings are ignored.
The screen is "zoomed" and only the middle shows. So I can't see the "start" menus.

Show us your boot.ini file in /media/boot/ directory.

After research, it looks like overscan. Trying to figure out my options. xrandr etc.
After more research, I needed to use a different HDMI port. I'm good now, thank you!

4.14 uses the new mainline kernel common driver where cec is an input device
Libcec is not yet compatible with it
Please use LIRC to use the new driver (configure cec like a remote control)

I tried, but without success.
Perhaps someone in the knowledge will write a howto.
What to use here - source, driver and device.

HK official kernel didn’t include cec driver at all.
They will enable it in the next update
Check if driver is enabled with:
dmesg | grep -i cec

Thank you memeka. Does your kernel fork 4.14 have a cec driver?

Both mine and HK's kernel have CEC driver since it's in mainline kernel.
But HK did not enable in config. They will enable it in their next update.

The same issue was discussed in other threads already.
Just wait for the next Kernel update and CEC might magically work.

I think we need to look into the new libcec too if it doesn't work.

Is HDMI-CEC already fixed?
Apparently, it was not just me who missed CEC after the Kernel update.

Update the kernel to 4.14.20 and test the CEC functionality.
cec-client and Kodi should work.

When we connected a Samsung TV, we could control the TV power with monitor on / off commands at least.
Which display do you test?

After the fresh installation and update of Ubuntu 16.04.3 (20171212) the result is the same. What are your steps for activating HDMI-CEC.

I have no idea at this moment because it is already Friday evening 8:00 PM.
Try this.

If it doesn't work, we will check the CEC functionality again early next week.

This was done with 3.10.y/ 4.9.y kernels. Unfortunately, something else is needed. We'll wait for a patch. :(
