ubuntu下使用DNW连接ARM2440问题
在网上下载dnw_linux后make -C /lib/modules/`uname -r`/build M=`pwd` modules
得到secbulk
然后sudo insmod ./secbulk.ko 
在运行dnw时显示
root@ubuntu:~/dnw_linux# ./dnw /media/BACKUP/linux-2.6.30/arch/arm/boot/zImage 
file name : /media/BACKUP/linux-2.6.30/arch/arm/boot/zImage
file size : 1945616 bytes
Can not open /dev/secbulk0
这是什么问题阿？为什么用不了阿？
这是dmesg后的部分显示
