    Hi i'm looking the device tree of neo because i would like to use ECSPI_2 or ECSPI_3 (A9 side). I saw on imx6sx-udoo-neo-externalpins.dtsi this :

    &ecspi2 {
    fsl,spi-num-chipselects = <1>;
    cs-gpios = <&gpio6 14 0>;
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_ecspi2>;
    status = "disabled";
    };

    I would like to enable it. How i can proceed ? Can i just modify uEnv.txt to enable the spi or do i need to recompile it with status enabled ?

    Thanks, i will take a look. Otherwise, on the device tree you make for neo, have you enabled ecspi2 or 3 ? If no, can you explain how to enable this on .dts(i) please ? Just for information, if i understand with uEnv.txt we can enable or disable device at boot time ?
