5网口模式的LED指示灯问题



  • 如果不使用 reg w 10000064 0x0
    reg w 1000003c 0xe001ff
    这两个命令,而是在为widora.dts上修改会出现如下错误!
    [ 0.090000] rt2880-pinmux pinctrl: found group selector 16 for ephy_p1
    [ 0.090000] rt2880-pinmux pinctrl: invalid group "ephy_p2" for function "ephy"
    [ 0.090000] rt2880-pinmux pinctrl: found group selector 18 for ephy_p3
    [ 0.090000] rt2880-pinmux pinctrl: found group selector 19 for ephy_p4

    DTS改动的地方是
    ephy_p1 {
    ralink,group = "ephy_p1";
    ralink,function = "ephy";
    };
    ephy_p2 {
    ralink,group = "ephy_p2";
    ralink,function = "ephy";
    };
    ephy_p3 {
    ralink,group = "ephy_p3";
    ralink,function = "gpio";
    };
    ephy_p4 {
    ralink,group = "ephy_p4";
    ralink,function = "gpio";
    };

    不知道是什么问题

    过后我跟踪一下源码看看哪里不匹配。
