通过 USB beaglebone black linux 进行 nfs

我正在尝试通过 USB 启动 nfs。到目前为止，我可以加载内核并使用以太网 USB 上的 tftp 使用 dtb 运行它。我路过

setenv bootargs console=ttyO0,115200n8 root=/dev/nfs rw rootfstype=ext4 rootwait fixrtc nfsroot=192.168.2.1:/home/mahathug/tftp/fs ip=192.168.2.2:192.168.2.1:192.168.2.1:255.255.255.0 nfsrootdebug earlyprintk

这无论如何都行不通。

这不起作用，因为我没有连接以太网电缆，它会搜索 phy 以太网，但我尝试::usb0在上面的命令中附加 ip 参数，它不会搜索以太网，但仍然出现错误

任何提示，或者消除这些的方法。

tftp 传输后，我在主机上没有收到任何日志 /var/log/syslog

我在内核配置中启用了 usb_eth 选项，以及 root_nfs 等所需的所有其他选项。

我不想单独使用以太网电缆。我想通过 USB 来完成

我知道这已经很旧了。我可能是错的，但我认为 USB 端口只有在操作系统加载后才能完全启动。即使它确实加载得更快，您的状态显示您仍然指向 eth0 作为引导设备。似乎这应该是 uEnv.txt 中的 usb0，但是当我尝试它时，我开始启动 USB... USB0：usb0 不可用。
