    您好，

    能否提供有关您的设置的更多信息？ 您使用的是什么硬件EVM平台，还是自定义主板？ 通常，由于未检测到IRQ引脚，会显示此错误。 在设备树中，您使用的是带外还是带内IRQ？

    使用的自定义主板，WLAN_EN(MMC2_SDCD 使用 GPIO0_38),  WLAN_IRQ(MMC2_SDWP使用 GPIO0_41)自定义引脚, 设备树相关配置如下：

    wlan_en: regulator-3 {
    /* OUTPUT of SN74AVC2T244DQMR */
    compatible = "regulator-fixed";
    regulator-name = "wlan_en";
    regulator-min-microvolt = <1800000>;
    regulator-max-microvolt = <1800000>;
    enable-active-high;
    regulator-always-on;
    vin-supply = <&vdd_3v3>;
    gpio = <&main_gpio0 38 GPIO_ACTIVE_HIGH>;
    pinctrl-names = "default";
    pinctrl-0 = <&wifi_en_pins_default>;
    };


    wifi_pins_default: wifi-pins-default {
    pinctrl-single,pins = <
    AM62X_IOPAD(0x0120, PIN_INPUT, 0) /* (C24) MMC2_CMD */
    AM62X_IOPAD(0x0118, PIN_INPUT, 0) /* (D25) MMC2_CLK */
    AM62X_IOPAD(0x0114, PIN_INPUT, 0) /* (B24) MMC2_DAT0 */
    AM62X_IOPAD(0x0110, PIN_INPUT, 0) /* (C25) MMC2_DAT1 */
    AM62X_IOPAD(0x010c, PIN_INPUT, 0) /* (E23) MMC2_DAT2 */
    AM62X_IOPAD(0x0108, PIN_INPUT, 0) /* (D24) MMC2_DAT3 */
    >;
    };

    wifi_en_pins_default: wifi-en-pins-default {
    pinctrl-single,pins = <
    AM62X_IOPAD(0x009C, PIN_OUTPUT, 7) /* MMC2_SDCD (V25)GPMC0_WAIT1.GPIO0_38 */
    >;
    };

    main_wlirq_pins_default: main-wlirq-pins-default {
    pinctrl-single,pins = <
    AM62X_IOPAD(0x00A8, PIN_OUTPUT, 7) /* MMC2_SDWP (M21)GPMC0_CSn0.GPIO0_41 */
    >;
    };

    &sdhci2 {
    status = "okay";
    vmmc-supply = <&wlan_en>;
    pinctrl-names = "default";
    pinctrl-0 = <&wifi_pins_default>;
    non-removable;
    ti,fails-without-test-cd;
    cap-power-off-card;
    keep-power-in-suspend;
    ti,driver-strength-ohm = <50>;
    assigned-clocks = <&k3_clks 157 158>;
    assigned-clock-parents = <&k3_clks 157 160>;
    #address-cells = <1>;
    #size-cells = <0>;

    wlcore: wlcore@2 {
    compatible = "ti,cc33xx";
    reg = <2>;
    pinctrl-names = "default";
    pinctrl-0 = <&main_wlirq_pins_default>;
    interrupt-parent = <&main_gpio0>;
    interrupts = <41 IRQ_TYPE_EDGE_FALLING>;
    };
    // TI-BLE-SDIO interface
    btti: btti@1 {
    compatible = "ti,cc33xxbt";
    reg = <1>;
    };
    };

    请问 查看AM6254数据手册中的 （ ALW PIN ） MMC2_SDCD 一定要使用   A15, A23, B17； MMC2_SDWP 一定要使用  A17, B15, B23；吗？用上面的 GPIO0_38   GPIO0_41 有什么影响？

    1.相关电路图如下，请问会有什么影响吗？

    将MMC2引脚用作GPIO0 38和GPIO0 41引脚不存在问题。 这是可以接受的。 这些引脚必须是GPIO引脚，因为CC33xx器件必须通过GPIO0 38启用，然后任何中断信号都将来自GPIO0 41，这也是必需的。
