20260428给万象奥科的开发板HD-RK3576-PI适配瑞芯微原厂的Android14时调通以太网卡芯片YT8521并实测网速898Mbits/sec

2026/4/28 12:35

缘起：

1、使用iperf3实测网速。略低于Buildroot系统的网速902Mbits/sec。可以尝试扫描RX/TX的延迟值。

2、必须新建临时目录export TMPDIR=/data/local/tmp，根据DeepSeek的建议，可以尝试放到mksh内！

snps,reset-active-low;

/* Reset time is 20ms, 100ms for rtl8211f */

&mdio0 {

rgmii_phy0: phy@1 {

};

};

//&mdio1 {

// compatible = "ethernet-phy-ieee802.3-c22";
// reg = <0x1>;
// clocks = <&cru REFCLKO25M_GMAC1_OUT>;
// };
//};

2、使用iperf3实测网速。略低于Buildroot系统的网速902Mbits/sec。

【基本可以确认iperf3需要一个临时目录】
