#0: wm8960-audio/random: nonblocking pool is initialized根文件系统问题求解

fang百川

根据正点原子提供的开发指南手册，已经移植u-boot和linux的情况下，构建根文件系统时初步测试，已经使用该命令测试，
setenv bootargs 'console=ttymxc0,115200 root=/dev/nfs rw nfsroot=192.168.0.109:/home/fang/linux/nfs/rootfs,proto=tcp ip=192.168.0.104:192.168.0.109:192.168.0.1:255.255.255.0::eth0ff'



出现如图的问题，然后系统就卡在这里了，


有人遇到过吗，可以指导一下吗谢谢

起个什么名字好

可能是nfs的配置有问题，可以看下这个帖子http://www.openedv.com/forum.php ... 7&highlight=nfs
还有你的Ubuntu是什么版本的？Ubuntu18及以上的需要修改下配置，这个帖子里也有写

感谢，是bootcmd 和bootargs 没有设置好的原因

1. setenv bootcmd 'tftp 80800000 zImage; tftp 83000000 imx6ull-alientek-emmc1.dtb; bootz 80800000 - 83000000'
   
2. setenv bootargs 'console=ttymxc0,115200 root=/dev/nfs rw nfsroot=192.168.0.109:/home/fang/linux/nfs/rootfs ip=192.168.0.106:192.168.0.109:192.168.0.1:255.255.255.0::eth0:off'
   
3. saveenv
