我遇到了使用rgmii+8211phy，无法找到网卡的问题

504566020 · February 12, 2025, 12:47pm

我使用rgmii接了一个8211Phy。
我借鉴了这个帖子RGMII not working on jetson agx orin

我修改了设备树，添加了ethernet@2130000 enable and configuration

我目前是，有了eth0这个新的网卡，但是
root@orin:~# ifconfig eth0 up
[ 159.387176] nvethernet 2310000.ethernet: [poll_check][42][type:0x4][loga-0x0] poll_check: timeout
[ 159.396316] net eth0: failed to poll MAC Software reset
SIOCSIFFLAGS: Operation not permitted
root@orin:~#
然而我不知道如何修改pinmux，并让这个配置在板子中生效。
请问下如何让修改pinmux，并让pinmux在板子上生效呢，如果不通过烧写img的方式行吗？比如，可以通过更换/boot下的设备树，生效吗？
以下是我的pinmux文件

root@orin:~# busybox devmem 0x22140a0
0x00000003
root@orin:~# busybox devmem 0x2214080
0x00000000
root@orin:~#
上边是我现在的值，我知道0x2214080寄存器，应该是0x1才对。
因为我是远程操作，要是通过flash.sh去烧写的话比较麻烦，不知道有什么方法，可以配置好这个gpio的值呢？

通过下边这个方法可以吗？
root@orin:~# busybox devmem 0x2214080 16 0x00000001
root@orin:~# busybox devmem 0x2214080
0x00000001
root@orin:~#

可以試試看devmem直接寫完之後做ifconfig eth0 down/up

但你最後還是得做重燒. 這只是簡易步驟而已重開機之後就會重設.

504566020 · February 13, 2025, 2:42am

明白，因为我是在远程调试，以后正式生产，会进行烧写的。

我配置了0x2214080 为0x00000001，但是执行ifocnfig eth0 up还是报错，如下：

root@orin:~# ifconfig eth0 up
[ 689.829159] nvethernet 2310000.ethernet: [poll_check][42][type:0x4][loga-0x0] poll_check: timeout

如果你是連document都沒讀過的話, 還是先確認一下以下內容

https://docs.nvidia.com/jetson/archives/r36.4.3/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxOrinSeries.html?highlight=rgmii

我剛才看了一下你的pinmux發現全部都沒有設定. 你這樣只改一根gpio enable/disable自然沒有什麼幫助

504566020 · February 13, 2025, 2:49am

哦好的。但是我现在板子，不在身边。能否，通过devmem去设置呢？

我想，我是否可以想这个帖子中

的下边的这些值去配置呢？
Here is pinmux dump log.

我现在修改了我的pinmux和gpio文件，如下：
tegra234-mb1-bct-gpio-p3701-0000-a04.txt (4.8 KB)
tegra234-mb1-bct-pinmux-p3701-0000-a04.txt (63.6 KB)
我现在烧写进去了。我的板子是，通过UPHY6接了一个AQR113C的万兆，以及一个pcie的rtl8111的phy，出来了两个网口，这两个网口是正常的，eth0和eth1。
现在是通过rgmii出来第三个网口，目前还是无法看到，该网口。请给予帮助。

504566020 · February 28, 2025, 8:26am

temp-dts.txt (552.3 KB)
这个是附件是我现在使用的dtb，通过dtc，反编译出来的dts文件。这里边有我添加的那个网口。
ethernet@2310000 {
status = “okay”;
nvidia,mac-addr-idx = <0>;
nvidia,phy-reset-gpio = <&tegra_main_gpio TEGRA234_MAIN_GPIO(G, 5) 0>;
phy-mode = “rgmii-id”;
phy-handle = <&phy>;
/delete-node/ fixed-link;

    mdio {
        compatible = "nvidia,eqos-mdio";
        #address-cells = <1>;
        #size-cells = <0>;

        phy: phy@1 {
            reg = <1>;
            nvidia,phy-rst-pdelay-msec = <224>; /* msec */
            nvidia,phy-rst-duration-usec = <10000>; /* usec */
            interrupt-parent = <&tegra_main_gpio>;
            interrupts = <TEGRA234_MAIN_GPIO(G, 4) IRQ_TYPE_LEVEL_LOW>;
        };
    };
};

现在我出来的网口，eth0地址居然是2310000，但是这并不是我得那个rgmii的口，附件是demsg打印信息。

现在我的这个rgmii出来的8211通了，但是我原来的那个pcie的8111网卡，却不见了。

我对这里比较迷惑，都无法通过mdio通信吗，但是我通过ethtool，还有mii-tool能看到信息呢。而且，我通过lspci是可以看到我的8111phy的。但是就是无法出来。我感觉那个ethernet@2310000，这个地址，是和pcie的8111冲突了？
