Uncompressing Linux.................................................................................................................................................... done, booting the kernel
原因：1、未在uboot的include/configs/mini2440.h 中添加了#define CONFIG_CMDLINE_TAG这个宏
2、机器码不匹配
宏定义 gedit include/asm/mach-types.h
引用 gedit board/samsung/mini2440/mini2440.c
内核定义 gedit arch/arm/tools/mach-types
3、串口参数填错 console=ttySAC0,115200
