求助：STM32MP157的bootfs加载失败问题！
您好！
跟着老师一步一步学习《第1.5讲 Linux驱动开发前的准备工作(必看)-根文件系统提取与测试》时bootfs加载失败，报错：
VFS: Cannot open root device "nfs" or unknown-block(2,0): error -6
Please append a correct "root=" boot option; here are the available partitions:

你nfs服务器开了吗？uboot是否配置了网络，是否可以ping通nfs服务器地址（也就是ubuntu的地址）？

RPCNFSDOPTS="--nfs-version 2,3,4 --debug --syslog”

烧录到EMMC中并通过EMMC启动bootfs，正常，但是通过nfs网络加载失败。

自动获取：电脑的IP设为DHCP模式试了一下也一样。
