20251213给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】系统时适配ETH1实测网速936 Mbits/sec
2025/12/13 9:24
缘起：飞凌OK3588-C开发板跑Rockchip原厂的Buildroot【linux-6.1】系统时，适配ETH1接口的网卡。
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、

2、刷机开发板OK3588-C后，没有eth0/eth1，根据以前的经验比对GPIO口的复用！
错误的GPIO复用：

搜索：【1 12 】
“1 12 ”
&gmac1 {
phy-mode = "rgmii-rxid";
clock_in_out = "output";
snps,reset-gpio = <&gpio1 12 1>;
snps,reset-active-low;
snps,reset-delays-us = <0 20000 100000>;
pinctrl-names = "default";
pinctrl-0 = <&gmac1_miim
&gmac1_tx_bus2
&gmac1_rx_bus2
&gmac1_rgmii_clk
&gmac1_rgmii_bus>;
tx_delay = <0x44>;
phy-handle = <&rgmii_phy1>;
status = "okay";
};
&pcie2x1l0 {
reset-gpios = <&gpio1 12 0>;
status = "okay";
};
3、拿掉pcie2x1l0
&i2s7_8ch {
status = "okay";
};
&mdio1 {
rgmii_phy1: phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <0x2>;
};
};
&mipi_dcphy0 {
status = "okay";
};
&mipi_dcphy1 {
status = "disabled";
};
// 2025/12/13 10:00 wenyuanbo add close for GMAC1 RESET
//&pcie2x1l0 {
// reset-gpios = <&gpio1 RK_PB4 GPIO_ACTIVE_HIGH>;
// status = "okay";
//};
&pcie30phy {
rockchip,pcie30-phymode = <PHY_MODE_PCIE_AGGREGATION>;
status = "okay";
};
4、使用iperf2进行网速测试：
