u-boot-1.3.2移植记录（三）

原文地址：u-boot-1.3.2移植记录（三） 作者：I-linux

由于linux镜像文件动则就有几百k，如果每次都用串口来传就太慢了。LIYUTAI的板子用的是RTL8019，U-BOOT上面直接有驱动，只要改一下就可以用了！（狂喜！！！）

调试网络的时候一直不通，后来调试之后发现原来是rtl8019.c出问题了。不知道为什么put_reg函数就有volatile而get_reg就没有，问题就出现在这里了。加上去，OK！

static unsigned char get_reg (unsigned int regno)

{

       return (*(volatile unsigned char *) regno);

}

 

为了调试U-BOOT，我真的详尽了办法，试了好多种方法都不能进行源码级的调试。后来发现了用RVDK可以在window下面进行调试，方法如下：（后来发现原来可以用skyeye来调试，连板子都可以不用上！谢谢skyeye的做着为我们提供这么好的平台）

修改arm_config.mk文件，增加-gdwarf选项

#PLATFORM_CPPFLAGS += -DCONFIG_ARM -D__ARM__

 

#debug

PLATFORM_CPPFLAGS += -DCONFIG_ARM -D__ARM__ -gdwarf-2

              接着在RVDK上面就可以进行源码级的调试了。爽啊~~~

在此要谢谢samfei的移植文档()，基本上对照着就能够完成u-boot-1.1.6。现在我把它移植到1.3.2，希望对新手有帮助。如果手上没有补丁文件，可以来信索取(E-mail: kenwucn@QQ.com)

取得补丁之后，可以直接给U-BOOT打补丁，直接得到需要的目标。

 

1)        把补丁文件放到与U-BOOT目录同级的位置

2)        进入U-BOOT目录

[root@localhost ken]# cd u-boot-1.3.2

[root@localhost u-boot-1.3.2]#

3)        打补丁（如果文件是gz格式）

[root@localhost u-boot-1.3.2]# gzip -dc ../u-boot-1.3.2-kenwucn.patch.gz | patch -p1
