第一步:打开电源 路径:kernelarcharm64bootdtsrockchiprk3568-evb1-ddr4-v10.dtsi pcie30_avdd0v9: pcie30-avdd0v9 { compatible = "regulator-fixed"; regulator-name = "pcie30_avdd0v9"; regulator-always-on; regulator-boot-on; regulator-min-microvolt = <900000>; regulator-max-microvolt = <900000>; vin-supply = <&vcc3v3_sys>; }; pcie30_avdd1v8: pcie30-avdd1v8 { compatible = "regulator-fixed"; regulator-name = "pcie30_avdd1v8"; regulator-always-on; regulator-boot-on; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; vin-supply = <&vcc3v3_sys>; }; vcc3v3_pcie: gpio-regulator { compatible = "regulator-fixed"; regulator-name = "vcc3v3_pcie"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; enable-active-high; gpio = <&gpio0 RK_PD4 GPIO_ACTIVE_LOW>; //控制电源引脚 startup-delay-us = <5000>; vin-supply = <&dc_12v>; regulator-always-on; regulator-boot-on; }; vcc3v3_bu: vcc3v3-bu { compatible = "regulator-fixed"; regulator-name = "vcc3v3_bu"; regulator-always-on; regulator-boot-on; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; vin-supply = <&vcc5v0_sys>; }; 第二步:打开DTS节点 路径:kernelarcharm64bootdtsrockchiprk3568-evb1-ddr4-v10.dtsi; &pcie30phy { status = "okay"; }; 第三步:查看设备节点是否生成(插入M.2固态硬盘) |
