01. 烧写内核

1.1 在minicom中输入如下命令

DengJin # dnw 40008000 OTG cable Connected! Now, Waiting for DNW to transmit data  

1.2 PC端下载zImage

[root@itcast linux-3.5_analyse]# dnw arch/arm/boot/zImage  load address: 0x57E00000 Writing data... 100%    0x0048FCF2 bytes (4671 K) speed: 1.175104M/S [root@itcast linux-3.5_analyse]#  

1.3 将内核写到SD卡

DengJin # movi write kernel 0 40008000 writing kernel..device 0 Start 1057, Count 12288  MMC write: dev # 0, block # 1057, count 12288 ... 12288 blocks written: OK completed DengJin #  

1.4 修改启动参数

DengJin # set bootcmd "movi read kernel 0 40008000;bootm 40008000" DengJin # save Saving Environment to SMDK bootable device... done DengJin #  

02. 设置启动参数

2.1 设置启动参数

# 设置bootargs参数 DengJin # set bootargs root=/dev/nfs nfsroot=172.16.0.53:/qtrootfs ip=172.16.0.251  console=ttySAC0,115200 lcd=S70 ctp=2 DengJin # save Saving Environment to SMDK bootable device... done # 显示环境变量 DengJin # printenv baudrate=115200 bootargs=root=/dev/nfs nfsroot=172.16.0.53:/qtrootfs ip=172.16.0.251  console=ttySAC0,115200 lcd=S70 ctp=2 bootcmd=movi read kernel 0 40008000;bootm 40008000 bootcmd1=movi read kernel 0 40008000;movi read rootfs 0 41000000 400000; bootm 40008000 41000000 bootdelay=3 ethaddr=00:40:5c:26:0a:5b gatewayip=192.168.0.1 ipaddr=192.168.0.20 netmask=255.255.255.0 serverip=192.168.0.10  Environment size: 414/16380 bytes DengJin #
