20251222给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】系统时拿掉type-C0的fusb302时适配adb功能dr_mode = "peripheral";
2025/12/22 20:28

缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】后，type-C0口改成4线的USB2.0口了。
可以刷机，由于没有fusb302芯片，相关DTS也需要做响应的修改以便使用adb功能！

虽然DEBUG能用，adb的功能属于锦上添花的功能，但是有些时候adb不能用还是特别不得劲！

需要实测开发板丝印ETH1芯片RTL8211F-CG的网速。
通过ifconfig确认为eth0。

需要使用ov5645的驱动框架来适配LVDS接口的105机芯。
按照以前的经验，首先关闭I2C的读写！
结果，肯定会出现某些地方遗漏的，只能通过编译器来检查问题了！

当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。
当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！

1、根据前面的调试的适配type-C1的USB3.0功能【接热像仪】的经验。
可以知道：type-C0拿掉type-C0的fusb302时适配adb功能，可能只需要如下【飞凌linux R4/Buildroot】3个代码块！

E:\fpga_OK3588_Linux_fs\kernel\arch\arm64\boot\dts\rockchip\OK3588-C-common.dtsi

&usbdp_phy0_u3 {
status = "okay";
};

&usbdrd3_0 {
status = "okay";
};

&usbdrd_dwc3_0 {
dr_mode = "peripheral";
usb-role-switch;
status = "okay";
port {
#address-cells = <1>;
#size-cells = <0>;
dwc3_0_role_switch: endpoint@0 {
reg = <0>;
remote-endpoint = <&usbc0_role_sw>;
};
};
};

2、使用Rockchip瑞芯微原厂的SDK，先适配好OK3588-C开发板，暂时先拼比了type-C0。
Y:\new_disk_4t\wyb\A8\rk3588_linux6.1_release_v1.2.0_20241220\kernel-6.1\arch\arm64\boot\dts\rockchip\rk3588-evb7-v11.dtsi
//&usbdrd_dwc3_0 {
// dr_mode = "otg";
// usb-role-switch;
// port {
// #address-cells = <1>;
// #size-cells = <0>;
// dwc3_0_role_switch: endpoint@0 {
// reg = <0>;
// remote-endpoint = <&usbc0_role_sw>;
// };
// };
//};

修改为：

&usbdp_phy0_u3 {
status = "okay";
};

&usbdrd3_0 {
status = "okay";
};

&usbdrd_dwc3_0 {
dr_mode = "peripheral";
usb-role-switch;
status = "okay";
port {
#address-cells = <1>;
#size-cells = <0>;
dwc3_0_role_switch: endpoint@0 {
reg = <0>;
//remote-endpoint = <&usbc0_role_sw>;
};
};
};

3、
&u2phy3_host {
phy-supply = <&vcc5v0_host>;
};

&usbdp_phy0 {
orientation-switch;
svid = <0xff01>;
sbu1-dc-gpios = <&gpio4 RK_PA0 GPIO_ACTIVE_HIGH>;
sbu2-dc-gpios = <&gpio4 RK_PA1 GPIO_ACTIVE_HIGH>;

port {
#address-cells = <1>;
#size-cells = <0>;
usbdp_phy0_orientation_switch: endpoint@0 {
reg = <0>;
remote-endpoint = <&usbc0_orien_sw>;
};

usbdp_phy0_dp_altmode_mux: endpoint@1 {
reg = <1>;
remote-endpoint = <&dp_altmode_mux>;
};
};
};

&usbdp_phy1 {
rockchip,dp-lane-mux = <0 1 2 3>;
};

&usbdrd_dwc3_0 {
dr_mode = "otg";
usb-role-switch;
port {
#address-cells = <1>;
#size-cells = <0>;
dwc3_0_role_switch: endpoint@0 {
reg = <0>;
remote-endpoint = <&usbc0_role_sw>;
};
};
};
