登录输入root后无法使用别的命令

xinmer

我在用调试串口登录输入root后，然后不知道跑哪里去了，无法使用其他命令是怎么回事？

chemist

可以通过pwd命令查看当前路径，然后不能使用其他命令可以重新刷一下固件试试，确认一下是否是固件有问题

我刷的固件是你们官方提供的，不是自己编译的，而且输入任何命令都没有效果

chemist

有没有可能是固件没有下载完整，有比对过md5值吗？然后可以把uboot和内核启动打印信息内容拍照看一下

还有一个最新的问题，我刚从你们这里下载的资料，用hash1.04校验的MD5值跟你们提供的对不上

chemist

md5值不对，你要问一下售后。或者重新下载试试。然后你这个开发套件是带显示屏的吗？是不是固件刷错了？

还有一个最新的问题，我刚从你们这里下载的资料，用hash1.04校验的MD5值跟你们提供的对不上

请使用飞凌提供的程序源码包，文件所在路径如下：
 用户资料\Linux\源码\xaa
 用户资料\Linux\源码\xab
 用户资料\Linux\源码\xac
说明：由于代码包超过 3G，所以才用分包形式：分成 xaa,xab,xac 三个文件。请以源码包程序为准。
生成目录结构，命令如下（该命令需要 root 权限）
# mkdir -p /root/workspace/allwinner/A40i/bsp
# cd /root/workspace/allwinner/A40i/bsp/
复制源码压缩包到虚拟机或者真实机器 /root/workspace/allwinner/A40i/bsp/
步骤 1：验证压缩包完成性，与 lichee_md5.txt 对比，命令如下
# md5sum xaa
# md5sum xab
# md5sum xac
步骤 2：生成源码压缩包，命令如下
# cat xa* > lichee.tar.gz
步骤 3：验证源码压缩包完整性，与 lichee_md5.txt 对比，命令如下
# md5sum lichee.tar.gz
步骤4：解压缩源码，命令如下。
# cd /root/workspace/allwinner/A40i/bsp/ # tar xvf lichee.tar.gz

我也遇到过输入命令无反应的情况，尝试更换串口线和双母头线试试

是我们的底板没有焊接网口，焊接上就好了，具体原因也不知道
