我在学到14.3讲,移植根文件系统的时候出了问题,开发板没办法通过NFS挂载Ubunto下的文件,
uboot和linux已经通过网络启动成功了,卡在了加载根文件那里了。
bootargs和bootcmd设置如下:
=> printenv bootargs
bootargs=console=ttymxc0,115200 root=/dev/nfs rw nfsroot=192.168.2.150:/home/li/linux/nfs/rootfs ip=192.168.2.151:192.168.2.150:192.168.2.1:255.255.255.0::eth0ff
=> printenv bootcmd
bootcmd=tftp 80800000 zImage;tftp 83000000 imx6ull-alientek-emmc.dtb;bootz 80800000 - 83000000
nfs安装和设定按照教程搞好了。帮忙看一下哪里出了问题。
