我尝试在我的设备上加载嵌入式Linux。
内核命令行:
setenv bootcmd 'nfs 10.0.0.1:/home/master/rootfs3/boot/uImage;bootm;'
setenv bootargs console=ttyTX0,57600n8 root=/dev/nfs rw nfsroot=10.0.0.1:/home/master/rootfs3 ip=dhcp init=/sbin/init
系统加载失败:
VFP support v0.3: implementor 41 architecture 1 part 10 variant 9 rev 1

- 这是什么意思,我在哪里可以知道这个错误?
答案 0 :(得分:0)
1.禁用防火墙 在我的Fedora 18上 systemctl停止firewalld systemctl禁用firewalld
2.Disable selinux vi / etc / selinux / config
- 评论SELINUX =强制执行 - 添加#SELINUX =禁用
重新启动你的Linux。
