I didn't notice that your pinctrl for sdmmc0 is wrong. (Because the cd pin are different) The sdmmc0 node should be like this: &sdmmc0 { bus-width = <4>; cap-sd-highspeed; cd-gpios = <&gpio0 RK_PB5 GPIO_ACTIVE_LOW>; disable-wp; no-1-8-v; pinctrl-names = "default"; pinctrl-0 = <&sdmmc0_bus4 &sdmmc0_clk &sdmmc0_cmd>; vmmc-supply = <&vcc3v3_sd>; vqmmc-supply = <&vcc_3v3>; status = "okay"; }; -- 2.25.1
