1、将makefile中的

CROSS =/usr/local/arm/2.95.3/bin/arm-linux-

CFLAGS+=-I/usr/local/src/2.4.18-rmk7/include

CFLAGS+=-I/usr/local/src/2.4.18-rmk7/include/linux

CFLAGS+=-I/usr/local/arm/2.95.3/arm-linux/include

路径改为你宿主机上的。

2、#make，来编译驱动模块。

3、#export PATH=$PATH:/usr/local/arm/2.95.3/bin //取决于你宿主机上的交叉编译工具路径

#arm-linux-gcc -o gpio_test gpio_test.c //编译应用程序

最终在你的当前文件夹下会生成gpiodrv.o与gpio_test两个文件。

4、#mkdir /tmp/1

5、通过ftp的方法，把gpio_test与gpiodrv.o文件下载到你的开发板上的/tmp/1目录中。

6、#mknod /dev/gpio c 220 0 //创建文件节点

#insmod gpiodrv.o

#chmod +x gpio_test

#./gpio_test

然后，就可以看到四个LED灯在闪烁了。:)-1, the makefile in the CROSS =/usr/local/arm/2.95.3/bin/arm-linux- CFLAGS+ =- I/usr/local/src/2.4.18-rmk7/include CFLAGS+ =- I/usr/local/src/2.4.18-rmk7/include/linux CFLAGS+ =- I/usr/local/arm/2.95.3/arm-linux/include changed the path on your host. 2,# make, to compile driver modules. 3,# export PATH = $ PATH:/usr/local/arm/2.95.3/bin// depends on your host on the path of the cross compiler tool# arm-linux-gcc-o gpio_test gpio_test.c// compile the application procedures for the ultimate in your current folder will be generated under the two documents gpiodrv.o and gpio_test. 4,# mkdir/tmp/1 5, through the ftp way to gpiodrv.o File Download gpio_test with the development of your board/tmp/1 directory. 6,# mknod/dev/gpio c 220 0// create a file node# insmod gpiodrv.o# chmod+ x gpio_test#./Gpio_test then four LED lights can be seen in the flicker of. :)
