Hello,

I've got a SCM-i.MX6DUal/6Quad Quick Start Board and followed the Quick Start Guide. Unfortunatelly, I do not get any output on two different Monitors connected to the HDMI port. Both monitors work with any other HDMI source I tried previously.

On the serial console I get the following messages:

imx-hdmi-audio imx-hdmi-audio: HDMI Video is not ready!
imx-hdmi-audio imx-hdmi-audio: ASoC: can't open platform imx-hdmi-audio: -22

The firmware is as delivered (extract from boot messages):

I already returned one unit because I thought the HDMI might be broken, but the new one shows the same behaviour.

Kind regards

Stephan
