Linux下DNW的USB驱动和写入工具

其中secbulk.c是USB驱动, dnw.c是写入工具

1. 编译
$make

编译成功后在当前目录下可以看到secbulk.ko 


2. 用insmod命令加载模块，这需要root权限
$sudo insmod ./secbulk.ko



3. 使用DNW下载
3.1 启动开发板，进入Supervivi，并将开发板和PC用USB电缆连接，此时用dmesg命令可以看到secbulk驱动加载：
[  283.677772] usb 1-1: new full speed USB device using uhci_hcd and address 2
[  284.084835] usb 1-1: configuration #1 chosen from 1 choice
[  284.140430] secbulk:secbulk probing...
[  284.140482] secbulk:bulk out endpoint found!

3.2 此时可以用supervivi进行USB下载，vivi上步骤请参考用户手册，当出现“USB host is connected. Waiting a download.”时，在PC端Linux上用dnw工具写入要下载的文件
$sudo ./dnw /path/to/what/you/want/download


具体命令见下
