    检查下你SD卡硬件山是否有连接SD卡插入检测引脚,如果没有连接的话要屏蔽掉board.dts中关于检测引脚的那一行。

    如下,注释掉:cd-gpios = <&pio PF 6 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;

    &sdc0 {
    	bus-width = <4>;
    	/*cd-gpios = <&pio PF 6 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;*/
    	/*non-removable;*/
    	/*broken-cd;*/
    	/*cd-inverted*/
    	/*data3-detect;*/
    	/*card-pwr-gpios = <&pio PH 14 1 1 2 0xffffffff>;*/
    	cd-used-24M;
    	cap-sd-highspeed;
    	/*sd-uhs-sdr50;*/
    	/*sd-uhs-ddr50;*/
    	/*sd-uhs-sdr104;*/
    	no-sdio;
    	no-mmc;
    	sunxi-power-save-mode;
    	/*sunxi-dis-signal-vol-sw;*/
    	max-frequency = <150000000>;
    	ctl-spec-caps = <0x8>;
    	/*vmmc-supply = <&reg_dcdc1>;*/
    	/*vqmmc33sw-supply = <&reg_dcdc1>;*/
    	/*vdmmc33sw-supply = <&reg_dcdc1>;*/
    	/*vqmmc18sw-supply = <&reg_eldo1>;*/
    	/*vdmmc18sw-supply = <&reg_eldo1>;*/
    	status = "okay";
    };

    检查下env.cfg环境变量配置是否正确。
