目标板中加载驱动时出现version magic '2.6.24.3 preempt mod_unload ARMv5 ' should be '2.6.30 mod_unload ARMv5 '错误

问题：

原来的内核版本2.6.24.3，交叉编译工具为ELDK4.1，通过rcS启动脚本自动加载驱动，继电器的驱动能在目标板上正常加载，并且运行正常。

内核版本升级到2.6.30，交叉编译工具的版本也升级到ELDK4.2，但是通过rcS启动脚本加载继电器驱动的时候，出现错误提示：

relay1218: version magic '2.6.24.3 preempt mod_unload ARMv5 ' should be '2.6.30 mod_unload ARMv5 'insmod: can't insert '/usr/relay1218.ko': invalid module formatBusyBox v1.15.3 (2012-06-04 11:17:39 CST) multi-call binaryUsage: mknod [OPTIONS] NAME TYPE MAJOR MINORCreate a special file (block, character, or pipe)Options:        -m      Create the special file using the specified mode (default a=rw)TYPEs include:        b:      Make a block device        c or u: Make a character device        p:      Make a named pipe (MAJOR and MINOR are ignored)

rcS启动脚本中，加载驱动部分的命令为：

# load drivers                                                                                                          /sbin/insmod /usr/relay1218.ko                                                                                          rm -f /dev/relay1218dev                                                                                                 mknod /dev/relay1218dev c `cat /proc/devices | grep "relay1218" | awk '{print $1}'` 0                                   chmod 664 /dev/relay1218dev

解决办法：

1. 检查驱动程序中的Makefile文件，其中的

KERNEL_SRC = /home/startech/Work/08src/linux-2.6.24.3/

而目标板上用的内核是2.6.30，这就是安装驱动时出现错误提示的原因。
原因找到了，下一步就是用目标板上的内核为基础来编译驱动；

2. 将驱动中的Makefile中的变量KERNEL_SRC改为2.6.30内核

出现N多错误：

3. 首先解决asm/arch/gpio.h找不到的问题。

asm/arch/gpio.h位于原来的2.6.24.3目录下的目录结构linux-2.6.24.3/include/asm-arm/arch-at91下面，

而asm是asm-arm的软链接，arch是arch-at91的软链接；所以arm/arch/gpio.h实际上就是linux-2.6.30/include/asm-arm/arch-at91/gpio.h；

但在2.6.30内核下，目录结构变了。linux-2.6.30/include/asm-arm下面只有区区两个文件asm-offsets.h和mach-types.h，而且都是自动生成的文件。

针对不同厂家的GPIO文件到哪里去了呢？

原来都挪到了linux-2.6.30/arch目录下，驱动程序的源程序中将头文件包含语句

#include <asm/arch/gpio.h>

改为

#include <../arch/arm/mach-at91/include/mach/gpio.h>

使用make命令重新编译

找不到arm/arch/gpio.h的提示消失了。

4. 但错误还是一大堆，从第一个错误开始看起，include/linux/prefetch.h的第14行

#include <asm/processor.h>

竟然调用的是linux-2.6.30/arch/x86/include/asm/processor.h，我要交叉编译arm，怎么会出来x86目录下的内容？

哦，原来驱动的Makefile文件中需要通过命令行方式来指定交叉编译工具和目标系统的；

将Makefile中的

make -C $(KERNEL_SRC) M=$(PWD) modules

改为

make ARCH=arm CROSS_COMPILE=arm-linux- -C $(KERNEL_SRC) M=$(PWD) modules

重新使用make命令编译
