移植uboot1.3.1到s3c2410（9）--编译并下载u-boot

5     编译并下载u－boot

5.1        编译u－boot

$make distclean

$make edukit2410_config

$make

编译成功之后，在当前目录下会生成u－boot.bin文件。

5.2        下载u－boot

这里我们采用powerice将u－boot.bin下载到nandflash0偏移处。

烧写完成后，运行minicom，显示串口输出信息：

[ edukit2410]#

按任意键终止自动运行模式。

5.3        使用u－boot自更新

1）更新不带图片显示的u-boot.bin

（1）           将编译生成的u－boot.bin拷贝到处tftp目录下面。

（2）           将u－boot.bin下载到sdram中间

[ edukit2410]# tftp 30000000 u-boot.bin                                         

（3）           擦除nandflash，起始地址为0，大小为0x30000

[ edukit2410]# nand erase 0 30000                                                                                                                             

（4）           将u－boot.bin固化到nandflash中

[ edukit2410]# nand write 30000000 0 30000

2）更新不带图片显示的u-boot.bin

（1）        将编译生成的u－boot.bin拷贝到处tftp目录下面。

（2）        将u－boot.bin下载到sdram中间

[ edukit2410]# tftp 30000000 u-boot.bin                                         

（3）        擦除nandflash，起始地址为0，大小为0x100000

[ edukit2410]# nand erase 0 100000                                                                                                                             

（4）        将u－boot.bin固化到nandflash中

[ edukit2410]# nand write 30000000 0 100000
