No HDMI signal on Cubox-i2exw

extravert · February 3, 2018 at 2:39 AM

Hi all!

I'm trying to run some linux distro other than stock Android on my cubox-i2exw.

I've installed LibreELEC v8.2.3 and it shows just black screen after U-Boot debug output. In the same time I see no errors in serial console, other distributions (geexbox, older versions of libreelec) behave more or less the same.

I was able to get an image on screen only with SolidRun's android.

How can this be fixed?

Here is LibreELEC console output:

Search in this forum for the imx6 release that vpeter ships with an older kernel and try that.

Thanks, now I'm able to get image on my monitor through hdmi-dvi cable.

But it still does not work with my TV, dmesg shows this messages:

Tried different resolutions in uEnv.txt, no result.

Sorry but I'm not familiar with this errors. Maybe it doesn't work with hdmi2dvi adapter (newer tested this).

It does work with hdmi2dvi but does not work with regular hdmi cable and TV

**vpeter** · February 4, 2018 at 6:26 AM

Sorry I read wrong.

HDMI cable and TV works here.

Try edit file uEnv.txt and set fdt_file manually for SoM v1.5.

Code

fdt_file=imx6q-cubox-i-som-v15.dtb

Looks like nothing has changed...

Then I'm out of ideas.
