解壓縮3.3.7內核
tar jxf linux-3.3.7.tar.bz2 -C /
cd /linux/3.3.7
修改基本make環境
vim Makefile
195: ARCH ?= arm
196: CROSS_COMPILE ?= arm-linux-
運行make help中找出最接近的平台
make s3c6400_defconfig
勾選平台MINI6410 注：s3c6410也可以，但是s3c6410默認並無網絡支持
make menuconfig
System Type --->
[*] MINI6410
uboot bootm啟動時會像內核傳遞平台代碼，設法解決平台編號問題
================= MACH-ID =================
u-boot:
vim include/configs/up6410_nand.h
or include/configs/up6410_sd.h
//#define MACH_TYPE 1626
#define MACH_TYPE 2520
or kernel:
vim arch/arm/tools/mach-types
#mini6410 MACH_MINI6410 MINI6410 2520
mini6410 MACH_MINI6410 MINI6410 1626
#smdk6410 MACH_SMDK6410 SMDK6410 1626
勾選相關的選項使內核支持NFS文件系統
=================== NFS ===================
make menuconfig
