Hi 295839633, To enable sdcard slot on sdmmc3, please make sure similar properties from sdmmc1 are present. mmc-ocr-mask = <0x0>; cd-inverted; cd-gpios = <&tegra_main_gpio TEGRA194_MAIN_GPIO(G, 7) 0>; nvidia,cd-wakeup-capable; mmc-ocr-mask = <0>; cd-inverted; vmmc-supply = <&p3668_vdd_sdmmc1_sw>; //you need to use the correct regulator from your carrier board status = "okay";
