Linux内核移植与根文件系统构建

使用Linux的时候,通过命令“ls /” 就会发现: 在/下包涵很多的目录,比如etc、usr、var、bin ... ... 等目录; 而在这些目录中还有很多的目录或文件; 文件系统在Linux下看上去就象树形结构, 所以可以把文件系统的结构形象的称为树形结构。 linux文件系统的最顶端是“/”; 我们称“/”为Linux的根,也就是 Linux操作系统的根文件系统。 Linux的文件系统的入口就是“/”,所有的目录、文件、设备都在“/”之下。

NXP Cortex-M3 LPC1768基础教程

首先说一说为什么写这个教程,转眼间就毕业了,学校的日子还没 有过够。就要工作了,由于需要想要搞一搞ARM M3,很显然芯片选型 落在了STM32 和NXP 的LPC17XX 上了。最后选择了LPC1768 这款型号, 买开发板、学习(以前我只用过单片机和一点点STM32),学习的过程 还算顺利,找到了ZLG 翻译的中文资料和3 个版本的例程。学习开始 了,从LED 灯、串口、AD、到内部定时器等等。学习的过程夹杂着 心酸和喜悦,在学习的过程中发现网络上还没有现成的学习资料。
