GPIO Issue

[majidBahmanigbt]

Hi, I would like to test “samples/basic/blinky” for IMX8MP. According to “zephyr/samples/basic/blinky/README.rst” in the first step I add the “leds” node to the device tree of boards/nxp/imx8mp_evk/ imx8mp_evk_mimx8ml8_adsp.dts.

/dts-v1/;

#include <nxp/nxp_imx8m.dtsi>
#include <nxp/nxp_imx/mimx8ml8dvnlz-pinctrl.dtsi>

/ {
    model = "NXP i.MX 8MPLUS Audio DSP";
    compatible = "nxp";

    leds {
        compatible = "gpio-leds";
        myled0: led_0 {
            gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
                };
    };

    chosen {
        zephyr,sram = &sram0;

        zephyr,console = &uart4;
        zephyr,shell-uart = &uart4;
    };

    aliases {
        led0 = &myled0;
    };

};

&gpiote {
    status = "okay";
};

&gpio0 {
    status = "okay";
};

&pinctrl {
    uart4_default: uart4_default {
        group0 {
            pinmux = <&iomuxc_uart4_rxd_uart_rx_uart4_rx>,
                <&iomuxc_uart4_txd_uart_tx_uart4_tx>;
            bias-pull-up;
            slew-rate = "slow";
            drive-strength = "x1";
        };
    };
};

&uart4 {
    status = "okay";
    current-speed = <115200>;
    pinctrl-0 = <&uart4_default>;
    pinctrl-names = "default";
};

However, when I compile the blink code, I receive the following error:
