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-
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-
[root@localhost u-boot-
3) 打补丁(如果文件是gz格式)
[root@localhost u-boot-
