用openjtag怎样烧写bios?

目前bootloader无法启动，想用OpenJtag烧写，请问如何做？谢谢！

我的板子是micro2440 256M的,打开电源后超级终端没有任何显示

谢谢总版主的回复！
我按照OpenJtag随机光盘里的说明操作如下：
在Nand flash启动模式下：


MMU: disabled, D-Cache: disabled, I-Cache: disabled
> load_image init\init.bin 0x40000000
288 byte written at address 0x40000000
downloaded 288 byte in 0.015625s
> resume 0x40000000
> halt
target state: halted
target halted in ARM state due to debug request, current mode: Supervisor
cpsr: 0x200000d3 pc: 0x400000bc
MMU: disabled, D-Cache: disabled, I-Cache: enabled
> load_image u-boot\u-boot.bin 0x33f80000
196760 byte written at address 0x33f80000
downloaded 196760 byte in 4.140625s
> resume 0x33f80000
> halt
target state: halted
target halted in ARM state due to debug request, current mode: Supervisor
cpsr: 0x400000d3 pc: 0x33f9e794
MMU: disabled, D-Cache: disabled, I-Cache: enabled
> load_image u-boot\u-boot.bin 0x30000000
196760 byte written at address 0x30000000
downloaded 196760 byte in 4.453125s
> resume
之后超级终端无显示无法执行烧写flash，是地址烧写有误，还是程序烧写错误？地址0x40000000我有试过0x0.结果一样
其中init.bin 和u-boot.bin均为OpenJtag随机光盘里的

操作步骤：
1. Eclipse,OpenOCD,OpenJTAGv3嵌入式开发教程 21页
2.换成台式机的串口，超级终端显示u-boot提示符。

经验证是OPENJTAG自带串口的问题

谢谢！
