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:
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。
