rk 3566 安卓11, 千兆网卡 rtl8211 调试记录
一、功能调试
1. 确认原理图
phy 常用的接口有两种 RGMII 和 RMII, 这两种对应的物理接口有 6 中如下所示. 首先需要根据原理图确定是哪种接法, 根据接法对应的 name 在文档 Rockchip_Developer_Guide_Linux_GMAC_Mode_Configuration_CN.pdf 中查找对应的配置.
1.1 RGMII 模式
该模式需要关注的硬件接口
mac: GMACX_MCLKINOUT , ETHx_REFCLKO_25M
phy: CLKOUT , XTAL_IN , XTAL_OUT
MAC
PHY
name
GMACX_MCLKINOUT 悬空ETHx_REFCLKO_25M 悬空XTAL_IN /XTAL_OUT 由晶体提供时钟PLL output 125M for TX_CLK, Crystal 25M for PH Y
GMACX_MCLKINOUT 悬空ETHx_REFCLKO_25M 提供时钟给 XTAL_OUT XTAL_IN 接地XTAL_OUT 由 ETHx_REFCLKO_25M 提供时钟PLL output 125M for TX_CLK, PLL 25M for PHY
GMACX_MCLKINOUT 时钟由 CLKOUT 提供ETHx_REFCLKO_25M 悬空XTAL_IN /XTAL_OUT 由晶体提供时钟125M TX_CLK input from PHY, Crystal 25M for PHY
GMACX_MCLKINOUT 时钟由 CLKOUT 提供ETHx_REFCLKO_25M 提供时钟给 XTAL_OUT XTAL_IN 接地,XTAL_OUT 由ETHx_REFCLKO_25M 提供时钟125M TX_CLK input from PHY, PLL 25M for PHY
1.2 RMII 模式
需要关注的引脚
mac: GMACX_MCLKINOUT , ETHx_REFCLKO_25M(一直悬空)
phy: PHY_TXCLK , XTAL_IN , XTAL_OUT
MAC
PHY
name
GMACX_MCLKINOUT 提供时钟给 XTAL_OUT ETHx_REFCLKO_25M 悬空XTAL_IN 接地XTAL_OUT 由 GMACX_MCLKINOUT 提供时钟RMII Clock Output
GMACX_MCLKINOUT 时钟由 PHY_TXCLK 提供ETHx_REFCLKO_25M 悬空XTAL_IN /XTAL_OUT 由晶体提供时钟RMII Clock Input
1.3 确认 name
确认 mac 端接口
根据原理图:
GMAC1_MCLKINOUT_M0 悬空 ==> GMACX_MCLKINOUT 悬空
ETH1_REFCLKO_25M_M0 悬空 ==> ETHx_REFCLKO_25M 悬空
确认 phy 端接口
根据原理图:
根据前面的信息可以推出 name 为 PLL output 125M for TX_CLK, Crystal 25M for PHY 在 rk 提供的文档 Rockchip_Developer_Guide_Linux_GMAC_Mode_Configuration_CN.pdf 查找对应的配置.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 &mdio1 { rgmii_phy1: phy@0 { compatible = "ethernet-phy-ieee802.3-c22" ; reg = <0x0 >; }; }; &gmac1 { phy-mode = "rgmii" ; clock_in_out = "output" ; snps,reset-gpio = <&gpio4 RK_PC2 GPIO_ACTIVE_LOW>; snps,reset-active-low; snps,reset-delays-us = <0 20000 100000 >; assigned-clocks = <&cru SCLK_GMAC1_RX_TX>, <&cru SCLK_GMAC1>; assigned-clock-parents = <&cru SCLK_GMAC1_RMII_SPEED>; assigned-clock-rates = <0 >, <125000000 >; pinctrl-names = "default" ; pinctrl-0 = <&gmac1m0_miim &gmac1m0_tx_bus2 &gmac1m0_rx_bus2 &gmac1m0_rgmii_clk &gmac1m0_rgmii_bus>; tx_delay = <0x4d >; rx_delay = <0x2d >; phy-handle = <&rgmii_phy1>; status = "okay" ; };
如果 dts 配置的不对会出现 dma 相关的报错, 出现这个报错, 按照前面的步骤确认硬件接法对应的name 然后查找对应的配置.
2. 配置驱动
这一步比较简单, rk 默认提供了该驱动的支持, 对应的路径 kernel/drivers/net/phy/realtek.c, 只需要打开宏 CONFIG_REALTEK_PHY 即可.
3. 配置电源
如果原理图上的 mac 的 io 供电由 vcc_1v8 提供, 软件需要配置打开这个 vcc_1v8 供电.
软件上对于 gmac1 的电源控制为 vccio5-supply , 因此需要做对应的映射
1 2 3 4 5 6 7 8 9 10 11 12 &pmu_io_domains { status = "okay"; pmuio1-supply = <&vcc3v3_pmu>; pmuio2-supply = <&vcca1v8_pmu>; vccio1-supply = <&vccio_acodec>; vccio3-supply = <&vccio_sd>; vccio4-supply = <&vcca1v8_pmu>; - vccio5-supply = <&vcc_3v3>; + vccio5-supply = <&vcc_1v8>; vccio6-supply = <&vcc1v8_dvp>; vccio7-supply = <&vcc_3v3>; };
这里如果没有配置正确的现象就是, 软件看起来一切正常, 可以读取 phy 信息, 能够 link up, 没有报错, 但是 ifconfig 读取不到 ip 地址 =_=.

二、吞吐量测试
pc 使用 iperf3 测试在 iperf3官网 下载安装, 下载后将 iperf3.exe 和 cygwin1.dll 复制粘贴到 C:\Windows\System32.
安卓 sdk 自带了这个工具, 在 external/iperf3 运行 mmm ./ 编译,out/target/product/rk3566_rgo/system/bin/, push 到机器里面使用.
1. 发送测试
pc端: 运行 iperf3.exe -s 后等待

2. 接收测试
发送测试反过来操作即可。
三、打开 led 灯
默认情况只亮一颗黄灯, 需要将另一颗绿灯点亮. 查看芯片手册, RTL8211F 的寄存器读写, 首先需要将要操作的 Address 对应的 page 写入 Page Select Register, 再对该寄存器进行读写.
要点亮灯对应检测到千兆网卡是亮灯需要将 bit8(绿灯), bit13(黄灯) 设置为 1. 首先往Page Select Register中写入对应的 page 0xd04, 然后再操作 0x10 寄存器. Page Select Register 如下所示.
编写代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 #define PHY_ID_RTL8211F 0x001cc916 #define PAGE_SELECT_ADDR 0x1f #define LED_PAGE_REG 0xd04 #define LED_CONTORL_REG 0X10 static int phy_rtl8211f_led_fixup (struct phy_device *phydev) int value = 0 ; if (phydev->phy_id != PHY_ID_RTL8211F) return 0 ; phy_write (phydev, PAGE_SELECT_ADDR, LED_PAGE_REG); value = phy_read (phydev, LED_CONTORL_REG); value |= (1 << 8 ) | (1 << 13 ); phy_write (phydev, LED_CONTORL_REG, value); return 0 ; }
完整修改如下
