我知道H3C 的br104h 88e6218 是ARMBOOT 的bootloader，四针的console RS232，TP-LINK的十针com口（串口)就不知定义是什么，可用超级终端恢复。方法是:
接上串口，当出现“Hit b for boot setup”的时候，敲入按键b。
Hit b for bootsetup

敲入printenv，可以看到网络的设置，可以看到br104h的ip地址为192.168.0.2，tftp 服务器的ip 地址为192.168.0.99
ARMboot->printenv
bootdelay=3
baudrate=38400
ethaddr=08:00:3e:26:0a:5b
ipaddr=192.168.0.2
serverip=192.168.0.99
netmask=255.255.255.000
bootfile=bootrom.bin
sdramImgAddr=0x00100000
flashAddr=0xFFF80000
bootSource=flash
Environmentsize: 201/4092 bytes
ARMboot->
然后设置网卡地址为192.168.0.99。下载tftpd32软件。设置需要下载的文件的路径和网卡接口。
然后，键入tftp命令将br104.bin文件下载到内存0x8000处（如果出现无法下载，请检查网络连接，ip地址，tftpd的设置）
ARMboot->
ARMboot->tftp 8000 br104.bin
Please wait,this takes a while ...
TFTP from server192.168.0.99; our IP address is 192.168.0.2
Filename'br104.bin'.
Load address:0x8000
Loading: #######
Bytestransferred = 33964 (84achex)
烧进flash的指令:
ARMboot-> protect off 0x50000 0x1fffff
ARMboot-> erase 0x50000 0x1fffff
ARMboot-> cp 0x0c008000 0x50000 20000
