SD卡不识别

32G sanDisk 的插入板卡中，报如下错误信息，从log上看可以得出已经识别，并读出大小，但是就是没法挂载成功

DTS 配置信息如下，热插拔引脚用的不是默认的热插拔


sdmmc: mmc@fe2c0000 {
                compatible = "rockchip,rk3588-dw-mshc", "rockchip,rk3288-dw-mshc";
                reg = <0x0 0xfe2c0000 0x0 0x4000>;
                interrupts = <GIC_SPI 203 IRQ_TYPE_LEVEL_HIGH>;
                clocks = <&scmi_clk SCMI_HCLK_SD>, <&scmi_clk SCMI_CCLK_SD>,
                         <&cru SCLK_SDMMC_DRV>, <&cru SCLK_SDMMC_SAMPLE>;
                clock-names = "biu", "ciu", "ciu-drive", "ciu-sample";
                fifo-depth = <0x100>;
                max-frequency = <200000000>;
                pinctrl-names = "default";
                pinctrl-0 = <&sdmmc_clk &sdmmc_cmd &sdmmc_det &sdmmc_bus4>;
                power-domains = <&power RK3588_PD_SDMMC>;
                status = "disabled";
        };





&sdmmc {
        max-frequency = <150000000>;
        no-sdio;
        no-mmc;
        bus-width = <4>;
        cap-mmc-highspeed;
        cap-sd-highspeed;
        disable-wp;
        //sd-uhs-sdr104;
        //vqmmc-supply = <&vccio_sd_s0>;
        vmmc-supply = <&vcc_sd>;
        cd-gpios = <&gpio4 RK_PB3 GPIO_ACTIVE_LOW>;
        cd-inverted;
        status = "okay";
};



那位大神帮看看怎么来定位是哪里的问题？

&sdmmc这部分重新加入：
                pinctrl-names = "default";
                pinctrl-0 = <&sdmmc_clk &sdmmc_cmd &sdmmc_det &sdmmc_bus4>;
这两行再试试看

我是通过另一个方法解决的，不用普通GPIO就可以，用默认的SD卡检测脚就没有问题
