CONFIGURE NuttX过程分析

前言

在使用Nuttx的过程中，第一步就是下载好源代码然后搭建编译环境，具体可以参考这篇外国小哥的博客CONFIGURE NuttX，具体的搭建过程就不详细叙述了，这次主要是记录下配置的过程。主要涉及的内容如下：

• nuttx/tools/configure.sh分析
• ${boardconfig}下的defconfig和Make.def

---

nuttx/tools/configure.sh

在明确开发板类型以后，我们采用上面超链接里面提到的步骤来配置：

• cd nuttx/nuttx-code/nuttx/tools
• **./configure.sh stm32f100rc_generic/nsh **
  到这里我们就直接去看看./configure.sh到底干了些什么。。。
  先贴上脚本～
