imx-hdmi-audio: HDMI Video is not ready!

[adrianhill]

I am trying to get started with a brand new SABRE i.MX6Quad board.

Using the Android distribution "out of the box" correctly boots, and displays Android on a regular HDMI monitor.

I then tried using the Linux distribution Linux 4.1.15_1.0.0 off the NXP page

IMX6_SW: i.MX 6 Series Software and Development Tool Resources

(without making any changes).

Booting off an SD card progresses until this message:

imx-hdmi-audio imx-hdmi-audio: ASoC: can't open platform imx-hdmi-audio: -22

imx-hdmi-audio imx-hdmi-audio: HDMI Video is not ready!

What am I doing wrong? I expected that the "official" distribution would "just work".

The version number from the boot text is:

Freescale i.MX Release Distro 4.1.15-1.0.0 imx6qdlsolo

(the full text from the boot, captured on TeraTerm is attached.

I also tried the Linux 3.14.52 archived version off the same page, but got the same result.

I can log in from a TeraTerm instance on a PC.

Any help would be much appreciated!

Thanks

Hi Adrian
