Hi,

How can I enable LVDS Display output in I.MX8QM Board, which dtb file, I have to load for enabling LVDS display.

I am able to get HDMI display by following dtb file fsl-imx8qm-mek-hdmi.dtb

Thanks & Regards,
Mallikarjuna B.

LVDS and MIPI Display is active by default in i.MX8QM MEY Evaluation Board. For HDMI you have to pass "hdmi" parameter while writing the image on board.  

I had tested it by through MIPI to HDMI and LVDS to HDMI converter.

the default dts file supports lvds already, which is imx8qm-mek.dtb

Hi,

I am getting following warning "it6263 7-004c: Probe failed. Remote port '/ldb@572410e0/lvds-channel@0' disabled" and at the same time I am getting HDMI display output properly.

Thanks & Regards,
Mallikarjuna B.

did you use nxp demo images? imx8qm-mek.dts doesn't enable the hdmi, pls double check if you use the correct dtb file
