用过EMC芯片的朋友都知道EMC的指令系统属于精简指令集(57条指令),这在做一些小程序时是非常方便的,但是如果程序较大,你就会发现,好多精力都被浪费在编写一些相似的指令上了,能否从中解脱出来呢?其实,如果你能善用EMC的宏指令,往往提高写程序的速度,并增加程序的可读性和可维护性-EMC Friend chips used all know EMC directive system are reduced instruction set (57 instructions), which make some small program is very convenient, but if a larger program, you will find that a lot of energy have been wasted in the preparation of some similar instructions on the can extricate themselves from it? In fact, if you can make the best use of EMC macros are often written procedures improve the speed and increase the program readability and maintainability

Discussing embedded systems in general is difficult, because each embedded system is unique. Rather than presenting a list of general principles for handling embedded development issues, this book presents examples of problems encountered and solutions to those problems using real hardware and software. In that sense, it is a “cookbook” for developers that offers design “recipes” that can be elaborated on or modified as needed to solve other design problems.

rootfs挂载 【mini_rootfs】
应用背景
本地挂载:
# setenv bootargs root=/dev/mtdblock4 init=/linuxrc console=ttySAC0,115200 rootfstype=yaffs rw
nfs方式挂载rootfs
本地PC端:
1 准备好/mini_rootfs
2 安装软件包
#apt-get install nfs-common nfs-kernel-server portmap
3 配置nfs服务
#vim /etc/exports
加上以下内容:
/mini_rootfs *(rw,sync,no_root_squash)
重启nfs服务器
#/etc/init.d/nfs-kernel-server restart
开发端:
1 配置内核以支持NFS启动
make menuconfig
