Touch Input Configuration for Multiple Displays in AAOS 15 on i.MX8QM

harshi03 — Thu, 25 Jun 2026 13:10:05 GMT

Hi Team,

I am using 10.1-inch HDMI LCD(E) touchscreen displays with the i.MX8QM board. I need guidance on how to properly connect these displays to the board and configure the touch input for each display. Specifically, I would like to understand which ports/interfaces on the board should be used to connect the touch input (USB). Additionally, I need help in correctly mapping each touch input to its corresponding display in the Android Automotive system.

Thanks & Regards

Hello,

i.MX 8QuadMax, support up to 4 displays:

Any combination of 2-4 displays of the following 4 displays: HDMI_TX, LVDS0_CH0, LVDS1_CH0, MIPI_DSI1.

Any combination of 2-4 displays of the following 4 displays: LVDS0_CH0, LVDS1_CH0, MIPI_DSI0, MIPI_DSI1.

Regarding the input configuration, I suggest you take a look in section 8.3.3.1 Binding the display port with the input port of Android Automotive User's Guide.

Best regards.
