这次重头再来，按照我之前的博客（NUTTX学习笔记）里面的内容来。 这次使用STM32F407ZET6的处理器，之前F1的板子因为要用stlink下载器有些麻烦，买了一个新板子还有一个Jlink下载器。
按照博主xiao2yizhizai对源码构建的博客，我们下载好的文件夹应该包含下面的文件：
nuttxapptoolsbuildroot打开nuttx里面的readme文件，在Instantiating “Canned” Configurations会有下面这一段文字
Only a few steps are required to instantiate a NuttX configuration, but to make the configuration even easier there are scripts available in the tools/ sub-directory combines those simple steps into one command. There is one tool for use with any Bash-like shell that does configuration steps. It is used as follows: tools/configure.sh < board-name >:< config-dir >
其中，config-dir是在对应单片机的readme文档内有说明，具体有好几种，这里我选用的是
tools/configure.sh 'mikroe-stm32f4:nsh'此时会出现mconfig没用配置的问题，打开{Topdir}/tools文件夹，打开read文件，在里面 General Build Instructions有安装说明，执行下面：
cd kconfig-frontends ./configure --enable-mconf make make install注意在输入make install的时候会提示一些库无法连接，要使用管理员模式：
sudo make install然后注意看控制台输出，会提示你这个库的安装路径还有你需要添加路径到系统：
---------------------------------------------------------------------- Libraries have been installed in: /usr/local/lib If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the '-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the 'LD_RUN_PATH' environment variable during linking - use the '-Wl,-rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to '/etc/ld.so.conf' See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages. ----------------------------------------------------------------------这里再按照博文 内的帮助，添加路径，但是这样做执行上一步配置单片机的时候还是会出现：
kconfig-conf: error while loading shared libraries: libkconfig-parser-4.11.0.so: cannot open shared object file: No such file or directory make: *** [do_olddefconfig] Error 127这里再执行
sudo ldconfig这样似乎就可以解决。
这样给系统选板子就完成了。运行
make qconfig出现图形界面 这样完成了基本的搭建，下面就是要编译。make一下就好
breeze@breeze-Inspiron-5559:~/nuttx/nuttx-8.1$ make出现一大段代码，直到最终出现
AR: stm32_boot.o stm32_spi.o stm32_clockconfig.o stm32_appinit.o make[2]: Leaving directory '/home/breeze/nuttx/nuttx-8.1/boards/arm/stm32/mikroe-stm32f4/src' LD: nuttx make[1]: Leaving directory '/home/breeze/nuttx/nuttx-8.1/arch/arm/src' CP: nuttx.hex CP: nuttx.bin说明已经生成了相应的bin和hex文件。最后查看一下文件列表：
breeze@breeze-Inspiron-5559:~/nuttx/nuttx-8.1$ ls arch boards crypto fs Kconfig Makefile nuttx pass1 sched System.map video audio ChangeLog Documentation graphics libs mm nuttx.bin README.txt staging TODO wireless binfmt COPYING drivers include Make.defs net nuttx.hex ReleaseNotes syscall tools说明编译应该是没什么问题。
下一步就是要看具体怎么配置，还有就是代码下载和app编写。代码下载要用Jlink下载，驱动安装可以参考我这篇博客:Ubuntu下Jlink驱动安装使用。
