(1)设置gcc

把所有gcc版本解压到/home/flinn/tools/目录下,以免切换编译器
export PATH=PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/flinn/tools/4.4.3/bin

 

(2)编译:
u-boot
  make mini2440_config
  make all

kernel
  make s3c2410_defconfig
  make menuconfig
  File system --->
    Miscellaneous filesystem --->
      <*> YAFFS2 filesystem support
  make uImage
