通过minicom和kermit利用串口下载内核映象和文件系统

HHARM2410-audio-r1的开发板,由于网卡不正常,故通过串口下载内核映象和文件系统.
1.启动minicom并开发板停在ppcboot状态,键入#loadb 30008000
2.建一个kermit配置文件:dot.kermitrc,内容如下
set line /dev/ttyS0
set speed 115200
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec pack 1000
set send pack 1000
set window 5
delete /var/lock/LCK..ttyS0 #minicom中的配置/var/lock
set line /dev/ttyS0
set speed 115200
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec pack 1000
set send pack 1000
set window 5
delete /var/lock/LCK..ttyS0 #minicom中的配置/var/lock
3.启动kermit,并传送文件,命令
#kermit -y /root/dot.kermrc
(/tftpboot/images/) C-Kermit>send zImage
就会出现传送画面,当传送完毕,回到minicom发现loadb已经回到提示符,随后可以用fl进行烧写了.
