器件型号：TDA4VH-Q1 工具与软件：
大家好、TI、
我们的硬件连接设置如下：
- CPSW9G port8 SGMII <-> SJA1110 SGMII
基于此连接、我们在 Linux 中进行了以下更改：
aliases {
serial0 = &wkup_uart0;
serial1 = &mcu_uart0;
//serial2 = &main_uart8;
//serial2 = &main_uart2;
serial2 = &main_uart3;
mmc0 = &main_sdhci0;
mmc1 = &main_sdhci1;
i2c0 = &wkup_i2c0;
i2c3 = &main_i2c0;
//MCU-CPSW2G TX
ethernet0 = &mcu_cpsw_port1;
//MAIN-CPSW2G TX
ethernet1 = &main_cpsw1_port1;
//MAIN-CPSW9G T1
//ethernet2 = &main_cpsw0_port3;
ethernet2 = &main_cpsw0_port1;
ethernet3 = &main_cpsw0_port2;
ethernet4 = &main_cpsw0_port3;
ethernet5 = &main_cpsw0_port4;
ethernet6 = &main_cpsw0_port5;
ethernet7 = &main_cpsw0_port6;
ethernet8 = &main_cpsw0_port8;
};
&serdes_ln_ctrl {
idle-states =
//SoC_SERDESw_LANEx_IPa_LANEb
//SERDES0
<J784S4_SERDES0_LANE0_PCIE1_LANE0>, <J784S4_SERDES0_LANE1_PCIE1_LANE1>,
<J784S4_SERDES0_LANE2_PCIE3_LANE0>, <J784S4_SERDES0_LANE3_IP4_UNUSED>,
//SERDES1
<J784S4_SERDES1_LANE0_QSGMII_LANE3>, <J784S4_SERDES1_LANE1_QSGMII_LANE4>,
<J784S4_SERDES1_LANE2_QSGMII_LANE1>, <J784S4_SERDES1_LANE3_QSGMII_LANE2>,
//SERDES2
<J784S4_SERDES2_LANE0_QSGMII_LANE5>, <J784S4_SERDES2_LANE1_QSGMII_LANE6>,
<J784S4_SERDES2_LANE2_IP3_UNUSED>, <J784S4_SERDES2_LANE3_QSGMII_LANE8>,
};
&serdes2 {
status = "okay";
serdes2_sgmii_link: phy@0 {
reg = <0>;
cdns,num-lanes = <2>;
#phy-cells = <0>;
cdns,phy-type = <PHY_TYPE_SGMII>;
resets = <&serdes_wiz2 1>, <&serdes_wiz2 2>;
};
serdes2_sja1110_link: phy@3 {
reg = <3>;
cdns,num-lanes = <1>;
#phy-cells = <0>;
cdns,phy-type = <PHY_TYPE_SGMII>;
resets = <&serdes_wiz2 4>;
};
};
&serdes_wiz2 {
status = "okay";
};
&main_cpsw0_port8 {
status = "okay";
phy-mode = "sgmii";
mac-address = [00 00 00 00 00 00];
phys = <&cpsw0_phy_gmii_sel 8>, <&serdes2_sja1110_link>;
phy-names = "mac", "serdes";
fixed-link {
speed = <1000>;
full-duplex;
};
};
同时、我们还修改了 CPSW 驱动程序：
我们还转储了相关的寄存器、 如下图所示：
寄存器地址 寄存器值
0x0c000810： 0x00000021
0x0c000814： 0x0000003C
0x0c000818： 0x00009801.
0x0c000820： 0x00001008.
在寄存器说明中、两端的 MAC 无法建立链路。 您能帮我弄清楚出了什么问题吗？
