Linux/AM5728: Linux/AM5728: Which DTS can I refer to?

Part Number: AM5728

Tool/software: Linux

Hi, Sir,

My hardware design is referenced to the am572x_gp_evm_REV_A3a.dsn, and I use ti-processor-sdk-linux-am57xx-evm-05.01.00.11.

I can't find the dts file like am57xx-evm-reva3.dts, I don't know which dts file I can refer to?

    Hello Yung,

    In the latest AM57xx Processor SDK releases the <Processor SDK>/board-support/linux-<version>/arch/arm/boot/dts/am57xx-evm-reva3.dtb file gets generated by using the dtbo device tree overlays located in <Processor SDK>/board-support/linux-<version>/arch/arm/boot/dts/ti/ directory. If you want to change or add something to am57xx-evm-reva3.dtb you will need to modify or enter the needed fragments in the device tree overlays.

    Best regards,
    Kemal

    Hi, Kemal,
    I want to change the LCD resolution. Would you tell me which DTS file has related setting?

    ex:
    panel-timing {
    clock-frequency = <68930000>;
    de-active = <1>;
    hactive = <1280>;
    hback-porch = <48>;
    hfront-porch = <48>;
    hsync-active = <0>;
    hsync-len = <32>;
    pixelclk-active = <1>;
    vactive = <800>;
    vback-porch = <8>;
    vfront-porch = <4>;
    vsync-active = <0>;
    vsync-len = <4>;
    };
