大部分项目设计需要一个稳定的Linux版本，但是又需要修复内核漏洞。这种情况下，跟随LTS版本升级，是最好的办法。
很多项目也需要改善Linux的实时特性。可以使用Linux Realtime patch实现。
在kernel.org下载 https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.tar.xz ； https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.52.tar.xz;https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patch-4.14.52-rt34.patch.gz。
在Xilinx网站下载https://github.com/Xilinx/linux-xlnx/archive/xlnx_rebase_v4.14_2018.3.tar.gz。
使用patch，将patch-4.14.52-rt34.patch， 应用到linux-4.14.52，得到linux-4.14.52-rt。
再使用diff，以Linux 4.14为基础，为xlnx_rebase_v4.14_2018.3.tar.gz创建patch。在将得到的patch文件，应用到linux-4.14.52-rt，得到linux-4.14.52-rt-xlnx。部分文件需要手工合并。
最后编译linux-4.14.52-rt-xlnx，或者放入petaLinux工程编译，启动可以成功，网络、SD卡、USB功能正常。
下面是启动log。
