Instantiating “Canned” Configurations
“Canned” 配置在这个文件夹下:
configs/<board-name>/<config-dir>
这里我用的开发板是stm32f429i-disco，configs这个文件夹下就有，然后里面是。。。看样子文件有点多啊，LCD USB 。。。。先看看README:
- Contents
- Development Environment
- GNU Toolchain Options
- LEDs
- UARTs
- Timer Inputs/Outputs
- FPU
- FSMC SRAM
- STM32F429I-DISCO-specific Configuration Options
- Configurations
Development Environment
开发环境，没说什么。
GNU Toolchain Options
看样子写文档的人漏掉了这个
LEDs
LED，可以用来表示系统的一些运行状态，自己看。
UARTs
串口，只有串口1和5是可以全双工的，其他的只能单工。
Timer Inputs/Outputs
定时器输入输出，可以输出一些波形
FPU
FPU，浮点运算器
FSMC SRAM
SDRAM，如果需要DMA，那么要配置外部SDRAM，因为内部SDRAM不能配置DMA。还可以配置FSMC SDRAM
STM32F429I-DISCO-specific Configuration Options
这部分超级多
Configurations
配置，直接使用以下指令：
> cd tools
>./configure.sh `STM32F429I-DISCO/<subdir>`
>cd -
>. ./setenv.sh
subdir这个该怎么选啊。。无语了。。一个一个的来？？仔细看了半天里面的文件，最后决定先用nsh这个文件夹。意思我猜是nuttx shell
并没有什么提示出现。看样子运行成功了。
喜闻乐见，找不到文件，好，cd - 是用来返回上次工作目录的，但是上次工作目录下根本没有这个文件。搜索一下，发现这个文件存在,但是都不在这个目录下。关掉终端，重新来一遍。
找到原因，居然是从nuttx cd 到tools里去的，cd - 后正确的目录应该是 tools的上级目录nuttx，无语。。这里应该说标注一下的啊。
你让那些闲得没事跑到configs下然后又一次性 cd 到tools目录下的人怎么办？
再往下读居然有subdir的说明。。。nsh就是NuttShell ，看样子我猜的没错。nsh会开启uart2，下面居然又列出11条小标题。。
往下找有一个usbmsc的subdir，是个例程，可以使用32板上的usbhub连接U盘，uart1 调试 nuttx shell。这个看起来很短，先来操作这个好了。。。重新运行一边configure.sh 和 setevn.sh
正常。
下面这个文档还有的就是前面提到的 mconf-based ，有空再说吧。。
回到上一个README。下面是要拷贝一些文件到nuttx下。最后说有configure文件可以更容易操作，看样子刚刚已经搞定了。下一步。
Refreshing Configurations
刷新配置，这里需要我刷新么？通过查找，发现这个make oldconfig可以备份当前的 .config 而这个文件是由刚刚 configure.sh 拷贝过来的。那就来备份一下呗。
真是好消息，kconfig-conf没有找到，看样子还是要安装刚刚那个mconf-based。好，在文档中寻找，提到这个kconfig在源tools下，git之。
git clone https://bitbucket.org/nuttx/tools
进去看看吧。。README
- genromfs-0.5.2.tar.gz
- kconfig-frontends
- General Build Instructions
- Graphical Configuration Tools
- –program-prefix=
- kconfig-frontends-3.3.0-1-libintl.patch
- kconfig-macos.patch
- kconfig-mconf Path Issues
- gperf
- kconfig-frontends for Windows
- Buildroot
- nxfuse
- osmocon
好，看一看，主要内容就是编译：
(最近系统崩溃了，新装的时候发现这里出错了，需要安装几个东西:
sudo apt install pkg-config gperf flex bison ncurses-dev qt5-default binutils-dev automake genromfs libfuse-dev libtool
先用apt全部安装即可)
cd kconfig-frontends
./configure --enable-mconf
make
make install
有这么一个问题，是博主zhao23333提出的，这个问题我测试了，确实有这样的问题，解决方法就如博客
Nuttx的源码构建和编译中所说一样就可以解决。
完成，退出tools。
再回到刚刚的nuttx/nuttx目录下执行
make oldconfig
呵呵，这下好了，是选目标板的，还是本机的？文档中说，输入？可以获得帮助。好，试一下。
There is no help available for this option.
好，这样的话，我就以为是目标板了，选arm
回显有点多，看起来它自己选了很多选项：
