各位好:
       本公司设计的板卡有两路网口,一路是千兆的以太网,使用网卡芯片KSZ9031接到ARM43777的rgmii1接口上,mdio_clk和mdio_data分别连接B17和A17使用CPSW驱动,该网口能正常工作。
另一路是PRU的网络使用网卡芯片TLK105L接到ARM am4377的pru1_mii1接口上,dio_clk和mdio_data分别连接A12和B12使用prueth驱动,在系统启动后无法识别到该网卡,串口终端报了如下红色部分错误:

设备树中参照了创龙的AM437X-IDK开发板增加了pru网络的配置,linux内核使用的是4.4.12的RT Linux内核,lsmod看出pru网络相关驱动也已经加载。完整的终端打印的启动log信息及设备树配置文件见附件,请帮助分析下可能是什么问题,非常感谢!

最佳答案

1. 是否确认了上电后,硬件上配置的pru网口的phy地址是否变了? 2. am4372.dtsi里面的compatible 不需要改,不同版本的内核会有所不同。 具体请查看: Documentation/devicetree/bindings/remoteproc/ti,pruss-remot ...

确认一下,上电后的phy地址和设备树里配置的是否一样。是否变了。

上电后,输入reboot指令重启启动(非断电重启),会有什么现象?

上电后,输入reboot指令重启启动(非断电重启),会有什么现象?

您好:
      还有个问题需要请教您一下,我参考贵公司TL437X-IDK开发板中的设备数文件发现am4372.dtsi中pru相关的定义使用的是pruss_wrapper定义的,我不太明白为什么要这样用,我把我的am4372.dtsi中的pru相关的定义:
pruss1: pruss@54400000 {
   compatible = "ti,am4372-pruss";
   ti,hwmods = "pruss";
   reg = <0x54400000 0x2000>,

         <0x54410000 0x8000>,
         <0x54420000 0x2000>,
         <0x54426000 0x2000>,
         <0x5442e000 0x31c>,
         <0x54432000 0x58>;
   reg-names = "dram0", "dram1", "shrdram2", "intc", "cfg",

   #address-cells = <1>;
   #size-cells = <1>;
   ranges;

    compatible = "ti,am4372-pruss-intc";
    interrupts = <GIC_SPI 20 IRQ_TYPE_LEVEL_HIGH
           GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH

    interrupt-names = "host2", "host3", "host4",
        "host5", "host6", "host8",
        "host9";
    interrupt-controller;
    #interrupt-cells = <1>;
   };
   pru1_0: pru0@54434000 {
    compatible = "ti,am4372-pru";
    reg = <0x54434000 0x3000>,
          <0x54422000 0x400>,
          <0x54422400 0x100>;
    reg-names = "iram", "control", "debug";
    mboxes = <&mailbox &mbox_pru1_0>;
   };
   pru1_1: pru1@54438000 {
    compatible = "ti,am4372-pru";
    reg = <0x54438000 0x3000>,
          <0x54424000 0x400>,
          <0x54424400 0x100>;
    reg-names = "iram", "control", "debug";
    mboxes = <&mailbox &mbox_pru1_1>;
   };
   pruss1_mdio: mdio@54432400 {
    compatible = "ti,davinci_mdio";
    reg = <0x54432400 0x90>;
    clocks = <&dpll_core_m4_ck>;
    clock-names = "fck";
    bus_freq = <1000000>;
    #address-cells = <1>;
    #size-cells = <0>;
    status = "disabled";

  };

改成使用pruss_wrapper

          <0x54410000 0x8000>,
          <0x54426000 0x2000>,
          <0x5442e000 0x31c>,
          <0x54432000 0x58>;
    reg-names = "dram0", "dram1", "shrdram2", "cfg",

启动只是打印如下错误:
[    8.453058] prueth pruss1_eth: unable to get pruss handle,
没有出现如下的错误:
[   11.038885] prueth pruss1_eth: couldn't connect to phy  ocp/pruss@54400000/mdio@54432400/ethernet-phy@0

[   11.038910] prueth pruss1_eth: no ethernet-mii1 node

详细的log和设备树文件见附件!
麻烦帮助指导下,非常感谢!

1. 是否确认了上电后,硬件上配置的pru网口的phy地址是否变了?
2. am4372.dtsi里面的compatible 不需要改,不同版本的内核会有所不同。
具体请查看:
Documentation/devicetree/bindings/remoteproc/ti,pruss-remoteproc.txt
