1.启动开发板,进入u-boot:(如果开发板中没有系统,可以通过用SD卡方式启动开发板进入)
U-Boot 2011.06 (Mar 19 2012 - 08:45:34) for MINI6410
CPU: S3C6400@667MHz
Fclk = 667MHz, Hclk = 133MHz, Pclk = 66MHz (ASYNC Mode)
Board: MINI6410
DRAM: 256 MiB
NAND: 512 MiB
MMC: SAMSUNG SD/MMC: Host controler CH0
SD card is SD_VERSION_2
SD/MMC size : 3911680 block * 512B = 1910MB
Video: no Video params found, try bootargs~~ 640x480x24 31kHz 59Hz
[petworm] video_hw_init: <640, 480, 640, 480>
Error: Bad gzipped data

  2.按任意键进入命令行状态后,运行dnw命令,文件存放地址作为参数传入(十六进制):
  MINI6410 # dnw 50008000
  Insert a OTG cable into the connector!
  3.插入USB电缆,连接主机和开发板,minicom会出现如下提示:
  USB Cable is Connected
  Now, Waiting for DNW to transmit data
  4.另开一个终端,加载secbulk驱动
  sudo insmod secbulk
  5.建立secbulk驱动设备节点(通过试验,可跳过此步):
  sudo mknod /dev/secbulk0 c 102 0
  6.运行dnw程序,将欲传送的uImage的带路径的文件名作为参数传入:
  sudo ./dnw uImage_a70 #(我们选择当前目录下的uImage_a70文件)
  回车后传输开始,直至传送完毕。Minicom端提示如下:
  Now, Waiting for DNW to transmit data
  Download Done!! Download Address: 0x50008000, Download Filesize:0x40de8
  Checksum is being calculated.
  Checksum O.K.
  主机端提示如下:
  liwei@liwei:~/Desktop/dnw_linux/dnw$ sudo ./dnw uImage_a70
  file name : uImage_a70
