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 format
BusyBox v1.15.3 (2012-06-04 11:17:39 CST) multi-call binary

Usage: mknod [OPTIONS] NAME TYPE MAJOR MINOR

Create 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

#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

Spring AOP详解 bijian1013 java spring AOP
最近项目中遇到了以下几点需求，仔细思考之后，觉得采用AOP来解决。一方面是为了以更加灵活的方式来解决问题，另一方面是借此机会深入学习Spring AOP相关的内容。例如，以下需求不用AOP肯定也能解决，至于是否牵强附会，仁者见仁智者见智。 1.对部分函数的调用进行日志记录，用于观察特定问题在运行过程中的函数调用
[Gson六]Gson类型适配器(TypeAdapter) bit1129 Adapter
TypeAdapter的使用动机 Gson在序列化和反序列化时，默认情况下，是按照POJO类的字段属性名和JSON串键进行一一映射匹配，然后把JSON串的键对应的值转换成POJO相同字段对应的值，反之亦然，在这个过程中有一个JSON串Key对应的Value和对象之间如何转换(序列化/反序列化)的问题。以Date为例，在序列化和反序列化时，Gson默认使用java.
【spark八十七】给定Driver Program，如何判断哪些代码在Driver运行，哪些代码在Worker上执行 bit1129 driver
Driver Program是用户编写的提交给Spark集群执行的application，它包含两部分作为驱动： Driver与Master、Worker协作完成application进程的启动、DAG划分、计算任务封装、计算任务分发到各个计算节点(Worker)、计算资源的分配等。计算逻辑本身，当计算任务在Worker执行时，执行计算逻辑完成application的计算任务

AOP通俗理解 cngolon spring AOP
1.我所知道的aop 初看aop,上来就是一大堆术语，而且还有个拉风的名字，面向切面编程，都说是OOP的一种有益补充等等。一下子让你不知所措，心想着：怪不得很多人都和我说aop多难多难。当我看进去以后，我才发现：它就是一些java基础上的朴实无华的应用，包括ioc，包括许许多多这样的名词，都是万变不离其宗而已。 2.为什么用aop&nb

代码之谜（四）- 浮点数（从惊讶到思考） justjavac 浮点数精度代码之谜 IEEE
在『代码之谜』系列的前几篇文章中，很多次出现了浮点数。浮点数在很多编程语言中被称为简单数据类型，其实，浮点数比起那些复杂数据类型（比如字符串）来说，一点都不简单。单单是说明 IEEE浮点数就可以写一本书了，我将用几篇博文来简单的说说我所理解的浮点数，算是抛砖引玉吧。一次面试记得多年前我招聘 Java 程序员时的一次关于浮点数、二分法、编码的面试，多年以后，他已经称为了一名很出色的
数据结构随记_1 lx.asymmetric 数据结构笔记
第一章 1.数据结构包括数据的逻辑结构、数据的物理/存储结构和数据的逻辑关系这三个方面的内容。 2.数据的存储结构可用四种基本的存储方法表示，它们分别是顺序存储、链式存储、索引存储和散列存储。 3.数据运算最常用的有五种，分别是查找/检索、排序、插入、删除、修改。 4.算法主要有以下五个特性：输入、输出、可行性、确定性和有穷性。 5.算法分析的
linux的会话和进程组网络接口 linux
会话：一个或多个进程组。起于用户登录，终止于用户退出。此期间所有进程都属于这个会话期。会话首进程：调用setsid创建会话的进程1.规定组长进程不能调用setsid，因为调用setsid后，调用进程会成为新的进程组的组长进程.如何保证？先调用fork，然后终止父进程，此时由于子进程的进程组ID为父进程的进程组ID，而子进程的ID是重新分配的，所以保证子进程不会是进程组长，从而子进程可以调用se
