RT-Thread的 英飞凌的bsp 有些代码是做成package的，所以我们scons --menuconfig一次然后更新包：
cd rt-thread/bsp/Infineon/psoc6-evaluationkit-062S2
scons --menuconfig
pkgs --update
复制代码现在可以复制rt-thread/bsp/Infineon/psoc6-evaluationkit-062S2目录备用
cp -a rt-thread/bsp/Infineon/psoc6-evaluationkit-062S2 ~/psoc6
复制代码因ThreadX RTOS原生使用cmake管理，所以笔者也以cmake组织工程编译。为写CMakeLists.txt，需要对刚刚拷贝出来的psoc6文件仔细分析哪些是bsp驱动、哪些是RT-Thread的HAL，哪些是RT-Thread的app。经过分析后发现，
1.真正有用的目录就是libs和packages两个目录，可以其它目录都删除了
2.libs和packages目录下的目录/文件并没有全部用上，需要分析SConscript后把结果写入CMakeLists.txt编译规则，具体可以参考笔者后附的完整CMakeLists.txt文件
