EVMK2H Rev40 uboot tftp nfs

我的板子是EVMK2H  Rev40 ,希望通过tftp下载内核,nfs挂载文件系统,uboot(ver=U-Boot 2017.01-gc68ed086bd (Mar 26 2018 - 14:05:34 -0400) 中设置如下:

setenv serverip 192.168.2.192
setenv ipaddr 192.168.2.193
setenv tftp_root k2h                  
setenv nfs_root /opt/tftproot/nfsroot
setenv boot net

setenv name_fdt uImage-k2hk-evm.dtb
setenv name_kern uImage-keystone-evm.bin
setenv name_mon skern-k2hk-evm.bin
name_fw_rd=k2-fw-initrd.cpio.gz

saveenv

当在uboot中输入命令boot时,能下载所有文件,但是没有我期望的运行内核并挂载NFS文件系统,

下载完成后就停下了,显示如下:

    出现上面的问题的原因是:使用ubuntu的归档管理器(图形界面)解压文件系统。
    解决办法:在终端使用命令行解压: sudo tar -xf your-file-system.tar.xz
