Zero3 OTG虚拟成RNDIS出现异常 #46

Open evaxige opened 1 year ago

evaxige commented 1 year ago

基本情况

烧录固件：Orangepizero3_1.0.0_ubuntu_jammy_server_linux5.4.125.7z

当前使用内核：https://github.com/orangepi-xunlong/linux-orangepi/tree/a187b273f42c0c5169d8ed46d2a0abece97fb0d4

PC电脑：Windows 7 64bit系统；

要实现的功能

使用Zero3的Type-C接口插入到电脑中，并虚拟成RNDIS类型的网卡；

遇到的问题

直接加载g_ether驱动会报错，操作如下：

# modprobe g_ether

[   96.967946] udc 5100000.udc-controller: registering UDC driver [g_ether]
[   96.968349] g_ether 5100000.udc-controller: failed to start g_ether: -2

对比Zero2开发板的驱动加载情况，手动载入usb_f_eem驱动，操作如下：

modprobe usb_f_eem
modprobe g_ether

[  170.854263] udc 5100000.udc-controller: registering UDC driver [g_ether]
[  170.854343] using random self ethernet address
[  170.854351] using random host ethernet address
[  170.855489] usb0: HOST MAC ee:57:e3:20:20:7d
[  170.855617] usb0: MAC b2:be:53:20:54:2e
[  170.855647] using random self ethernet address
[  170.855654] using random host ethernet address

这时PC机上可以看到设备，加载对应驱动（参考：https://supportcommunity.zebra.cn/s/article/000014464）之后，但是会提示网卡无法启动，具体为：“该设备无法启动。 (代码 10)”，同时Zero3的dmesg会出现如下的错误信息：

[  171.127318] ERR: Operation not supported

打开调试信息重新编译驱动，更详细的异常信息如下：
