Genio 1200-EVK
This page provides board-specific information on the display interfaces of the Genio 1200-EVK. For common display and compositor information, please visit the Display page.
Display Interfaces on Genio 1200-EVK
IoT Yocto supports five display interfaces on Genio 1200-EVK:
DisplayPort(DP) through USB Type-C port
Embedded Display Port(eDP) with eDP Panel
INNOLUX HK173VB-01BLVDS with LVDS Panel
KOE TX18D204VM0BAA
The board can be used headless or in single, dual and triple display configurations.
The display system has three different pipelines - VDOSYS0-main, VDOSYS0-sub, and VDOSYS1 - that can be used for any of the triple display combinations. These pipelines are abstracted as different crtc in the DRM framework.
VDOSYS0-main and VDOSYS0-sub provide individual 3840x2160, 30Hz refresh rate and can be merged into one 3840x2160, 60Hz refresh rate display pipeline. VDOSYS1 provides 3840x2160, 60Hz refresh rate.
In the case of dual display combinations, VDOSYS0-main and VDOSYS0-sub are merged into one pipeline, together with VDOSYS1 to connect two connectors. In the case of triple display combinations, VDOSYS0-main, VDOSYS0-sub, and VDOSYS1 are independent pipelines to connect three connectors.
Default rity-demo-image enables dual display DSI0 and HDMI. Other display combinations can be enabled by loading the device tree overlay during the flash programming process.

Note
DSI1 port (LCM2) is still not supported on IoT Yocto in v25.x.
The LVDS connector is not supported in the v25.x migration. Please refer to the v24.1 implementation. LVDS shares the same data lanes as the eDP connector, so only one of them can be used at a time.
Lists of Display Device Tree Overlay
Starting from v25, none of the EVK default DTS files enable any display interfaces; loading the relevant DTBOs is required to enable them.
For the G1200 EVK, the default configuration loads display-dsi.dtbo and display-hdmi.dtbo.
$ genio-flash -i rity-demo-image
Genio Tools: v1.7.0a1
Yocto Image:
...
machine: genio-1200-evk
overlays: ['display-hdmi.dtbo', 'video.dtbo', 'display-dsi.dtbo', 'apusys.dtbo']
If you do not need display-dsi.dtbo, use the unload-dtbo option to remove the default display-dsi.dtbo
$ genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo
Genio Tools: v1.7.0a1
Yocto Image:

DSI0 + HDMI
DSI0 + HDMI are the default dual display interfaces for the prebuilt rity-demo-image. A DSI panel is pre-connected to G1200 EVK.
Flash the board with:
$ genio-flash -i rity-demo-image
Genio Tools: v1.7.0a1
Yocto Image:
...
machine: genio-1200-evk
overlays: ['display-hdmi.dtbo', 'video.dtbo', 'display-dsi.dtbo', 'apusys.dtbo']
As shown in the example above, both display-dsi.dtbo and display-hdmi.dtbo are loaded by default.
After boot into the console you can use modeprint mediatek command to check if both DSI0 and HDMI ports have been properly configured:

Headless
Headless means that Yocto works without enabling any physical display connector.
There is a virtual display at /dev/dri/renderD128 prepared for offline rendering.
To enable Headless, unload the overlay file display-dsi.dtbo and display-hdmi.dtbo during flashing process:
genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo
If you don’t want to re-flash the entire root file system, you can simply update the overlay configuration with:
genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo kernel mmc0boot1
After boot into the console you will see the following error log which is because there is no physical display for Weston desktop rendering:
[FAILED] Failed to start Weston, a compositor, as a system service.
See 'systemctl status weston.service' for details.
You can use modeprint mediatek command to check if headless has been properly configured by checking if connector count equals 0:

Note
For the triple display overlay, since there is an extra pipe setting for each encoder, we keep the original triple display overlay mechanism instead of loading three single-connector overlays. Unload both the DSI and HDMI DTBOs, and load the triple display DTBO.
As you can see, the
mediatek,indicated-display-pathtag is added to each encoder node in the overlay.

The associated display data pipeline can process up to 2.5K(2560 x 1600) with 60Hz refresh rate for DSI0, 4K(3840 x 2160) with 60Hz refresh rate for HDMI, and 4K(3840 x 2160) with 30Hz refresh rate for DP.
eDP + HDMI + DP
To enable eDP + HDMI + DP, load the overlay file display-edphdmidp.dtbo during flashing process:
genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo --load-dtbo display-edphdmidp.dtbo
If you don’t want to re-flash the entire root file system, you can simply update the overlay configuration with:
genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo --load-dtbo display-edphdmidp.dtbo kernel mmc0boot1
After boot into the console you can use modeprint mediatek command to check if eDP, HDMI and DP ports have been properly configured:
root@genio-1200-evk:~# modeprint mediatek

Hardware Setup for eDP
The prebuilt rity-demo-image supports INNOLUX HK173VB-01B panel with an eDP cable, as shown below:
Please always use this associated cable to connect to the panel. Connect either side to the Genio 1200-EVK board and to the panel. Make sure to remove the jumper on the Genio 1200-EVK board to enable the eDP path, as shown below:
Hardware Setup for LVDS
The prebuilt rity-demo-image supports KOE TX18D204VM0BAA panel with a LVDS cable, as shown below:
Please always use this associated cable to connect to the panel. Connect either side to the Genio 1200-EVK board and to the panel, as shown below:
Make sure to connect a jumper on the Genio 1200-EVK board to enable LVDS path, as shown below:
