ifneq ($(KERNELRELEASE),) obj-m := MiniX.o else KDIR := /home/hi/pi/kernel/linux/ all: make -C $(KDIR) M=$(PWD) modules ARCH=arm CROSS_COMPILE=/home/hi/pi/kernel/RpiTools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi- clean: rm -f *.ko *.o *.mod.o *.mod.c *.symvers modul* endif
编写main.c
#include <linux/init.h> #include <linux/module.h> #include <linux/moduleparam.h> MODULE_LICENSE("Dual BSD/GPL"); static int hello_init(void) { printk(KERN_ALERT"Hello, world\n"); return 0; } static void hello_exit(void) { printk(KERN_ALERT"Goodbye, cruel world\n"); } module_init(hello_init); module_exit(hello_exit);
