Can IMX93 EVK support Dual Display via LVDS and HDMI

[AlanWen]

I'm porting on LVDS and HDMI function, as the HDMI function works well on custom IMX93 board, while enabling the LVDS port in device tree failed the HDMI DSI output with error: -517 as below.

Is it possible to display on both HDMI and LVDS panel on IMX93 ?

Hopes someone could help me figure it out. Thanks in advance.

Is there any update about the dsi probe failed on i.MX93 for LVDS and DSI dual display ?

[Rita_Wang]

For the HDMI does it from the mipi-dsi? i.MX93 can support LVDS and MIPI dual display at the same time.

[AlanWen]

Yes, the HDMI signal is from the dsi output. Is there any other setup should I do for dual display through LVDS and HDMI on i.MX93 ?

[Rita_Wang]

Which version BSP are you using?

[AlanWen]

I'm using the 6.6.3 linux kernel
