Hi All,


I am working on customer imx6q board and getting issue with HDMI.

I am getting HDMI panel detection kernel log but no display on HDMI panel.

I am using rootfs which i have created by busybox.

So my question, Is there any need of "mxc hdmi cec" lib or application in user space to enable HDMI in kernel ?

or HDMI display should start by default ?
