MT7620运行OP后，程序跑飞问题

Xi***

hi给位大神，从仓库上下载编译后openwrt。烧录固件启动后，内核初始化后半段跑飞了，不确定是文件系统出现问题，还是内核配置出现问题。

烧录官当的 openwrt-ramips-mt7620a-mt7620a-squashfs-sysupgrade.bin 就会出现跑飞的问题。打印信息在下面。

然而我烧录 openwrt-ramips-mt7620a-mt7620a_mt7530-squashfs-sysupgrade.bin 、openwrt-ramips-mt7620a-mt7620a_mt7610e-squashfs-sysupgrade.bin
这两个固件的时候竟然能启动成功，通过TTL能够顺利的进入命令行，不过网络是不通的，ping主机一直不通。

我想现在的问题是不是由于我的硬件电路与官方的不一致导致开启失败。我用的电路板上只有一个MT7620A cpu。
望各位大神赐教～！

搞了一天，终于能够开机并且开启中断。

主要是将下面红色部分去掉

ethernet@10100000 {
                status = "okay";

                pinctrl-names = "default";
                pinctrl-0 = <&rgmii1_pins &rgmii2_pins &mdio_pins>;

                ralink,port-map = "llllw";

                port@4 {
                        status = "okay";
                        phy-mode = "rgmii";
                        phy-handle = <&phy4>;
                };

                port@5 {
                        status = "okay";
                        phy-mode = "rgmii";
                        phy-handle = <&phy5>;
                };

                mdio-bus {
                        status = "okay";

                        phy4: ethernet-phy@4 {
                                reg = <4>;
                                phy-mode = "rgmii";
                        };

                        phy5: ethernet-phy@5 {
                                reg = <5>;
                                phy-mode = "rgmii";
                        };
                };
        };


有大神知道时什么原因吗？dts文件是什么文件？

忘了说，这个文件是 MT7620a.dts

你的无线正常吗，我这几天编优酷路由宝的，无线连界面死活没有，后来下了rt2860v2驱动，界面有了，还是设置不了，编译好几次了。还是不行

谁给一个优酷路由宝的dst，对着东西不懂
