1.连接开发板和和pc之间的usb转串口线，usb线，在pc端打开vim，启动minicom
2.使用sd卡启动开发板，进入uboot
3.输入dnw，会有如下提示
TINY4412 # dnw
OTG cable Connected!
Now, Waiting for DNW to transmit data
4.在pc中打开新的vim，输入lsusb，会有如下提示

记住ID 04e8:1234 Samsung Electronics Co., Ltd 中的04e8:1234
5.解压下载的dnw
进入驱动目录
ning@ENVY:/$ cd /tiny4412/dnw-linux/src/driver/
打开驱动文件
ning@ENVY:/tiny4412/dnw-linux/src/driver$ vim secbulk.c
将idProduct和idVendor改为USB_DEVICE(0x04e8, 0x1234)
6.进入dnw目录
ning@ENVY:/tiny4412/dnw-linux/src/driver$ cd ../dnw/
修改下载地址
*((u_int32_t*)write_buf) = 0xc0000000;
记住这个地址，待会dnw会下载至这个地址，然后从这个地址拷贝
7.make 编译
8.拷贝dnw到制定目录
ning@ENVY:/tiny4412/dnw-linux/src/dnw$sudo cp dnw /usr/bin/
9.装载驱动
ning@ENVY:/tiny4412/dnw-linux/src/dnw$ cd ../driver/
ning@ENVY:/tiny4412/dnw-linux/src/driver$ sudo insmod secbulk.ko
为了不每次都装载可以打开
ning@ENVY:/tiny4412/dnw-linux/src/driver$sudo gedit /etc/init.d/rc.local
在文件中加入 sudo insmod /tiny4412/dnw-linux/src/driver/secbulk.ko
10.
dmesg(注意此时开发板依然显示OTG cable Connected!Now, Waiting for DNW to transmit data)
