I am using the IMX6 sabre board. I have flashed the yocto-mx-sabreauto-sdcard-sd3 image using mfgtool2. The main purpose of the board is to display a video but I am not able to get any HDMI output when connected to a screen. Also after booting up, I am getting the following error.

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

Hi Ajay

what is full name of board, if this is Sabre SD then

mfgtool2-yocto-mx-sabresd-sdcard-sd2.vbs should be used.

Also valid kernel boot parameter should be used, please check p.14

attached Linux Guide. Use "True" HDMI display with special HDMI cable,
not HDMI - DVI adapter.

Best regards
igor

Board name : MX6Q-Sabreauto revA

P14 of which document should I check. Also we tried using a HDMI-VGA adapter. Would it not work that way?

Thanks
