一、提取原码到自定目录

cd /home/Project/FireHydrant/project-workspace/N32926_BSP/

tar xvzf W55FA92BSP2.6.35_160115.tar.gz

cd W55FA92BSP2.6.35_160115/

二、按装BSP到自定目录

         原厂为我们做了一个安装脚本，我们只要运行它就可以了。
         ./w55fa92bsp_install.sh
         这里它会让我们输入按装路径，笔者放到如下目录。

/home/Project/FireHydrant/project-workspace/N32926_BSP/w55fa92bsp-2.6.35

三、试编译BSP

cd /home/Project/FireHydrant/project-workspace/N32926_BSP/w55fa92bsp-2.6.35/linux-2.6.35.4/

原厂为我们做了一个配置脚本，我们用的芯片是N32926，所以用w55fa92_defconfig这个配置。

运行：make w55fa92_defconfig

这时可以看到configuration written to .config

说明已成功生成.config配置文件了

接下来编译（说明：原厂BSP是将编译好的内核与文件系统打包成一个可执行文件，我们可以直接用他们的脚本，脚本可以制作不同的启动方式文件，我们用的是NAND）

./build nand

编译一会就出现了错误

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at kernel/timeconst.pl line 373.

/home/Project/FireHydrant/project-workspace/N32926_BSP/w55fa92bsp-2.6.35/linux-2.6.35.4/kernel/Makefile:138: recipe for target 'kernel/timeconst.h' failed

make[1]: *** [kernel/timeconst.h] Error 255

这是因为新的make规则编译较老的Makefile可能有冲突，我们可以按照提示修改一下。

将kernel/timeconst.pl中第373行的defined()去掉只留下@val

继续编译。。。

编译成功，并生成可执行文件在image目录下。

我们将它放到板子上试运行。控制台将看到如下信息：

有没有用过./build yaffs2 啊？好像之前我用别的系统不稳定！！
