解决nfs挂载根文件系统报错:VFS: Unable to mount root fs via NFS, trying floppy.

目录项目场景:问题描述原因分析:解决方案: 项目场景:arm开发板的linux根文件系统由烧录而得,从板子的mmc中读取根文件系统,但是如果在开发调试过程中,这个文件系统有修改,怎样将其保存下来,方便烧录到其他批量生产的板子上呢。将板载根文件系统导出,生成ext4格式的文件,这自然是个方法!但是此法繁杂,不实用。正点原子的开发板是这样做的,用nfs挂载虚拟机ubuntu中的根文件系统。问题描述我在虚拟机ubuntun搭建了nfs服务器(见博客Ubuntu上搭建nfs服务器,方便开发板远程挂载根文件系统_汉尼拔勇闯天涯的博客-CSDN博客),在开发板的uboot内设置了bootargs(sete
