Uboot for mini6410 移植步骤详解.doc

这是u-boot-2010.09 针对友善之臂MINI6410移植的最基础版本，只包含了就基本的系统引导，NAND读写，DM9000网卡等等。但是这个足够开发的方便使用。今后会陆续添加原先我为mini2440添加的所有功能。 但是此次移植并非我的功劳，首先基本的移植是由Alex Ling 完成的，你可以在这里看到他提交的补丁，但是编译后无法使用，可能是因为host系统不同，对脚本的解析不同，使得spl部分的生成出现问题,只需修改一下nand_spl目录下目标板目录的中config.mk中的PAD_TO:= $(shell expr $(TEXT_BASE) + 4096)即可。 DM9000的驱动没有太大的问题（修改了一点可能出现问题的地方，感谢肖工指教），但是原本的u-boot并没有调整所有SROM控制器的配置（其中包括连接DM9000所使用的bank1的总线），我使用了友善带的u-boot的参数配置了一下就好了。一：/batch.viewlink.php?itemid=1694ftp:/ftp.denx.de/pub/u-boot/去这2个网站随便下载都可以下载得到最新或者你想要的u-boot。现在我将下载u-boot-2010-09，这个也就是最新的版本啦。下载后把它解压，然后得到u-boot-2010-09的文件夹，然后进去，并且做下面几件事情：1：进入arch这个文件夹，把出arm外的前部文件夹删掉2：进入board这个文件夹，把除samsung外前部文件夹删掉3：进入include/configs，把除smdk6400.h外的所有文件删除。4: 把顶层目录下有一个叫onenand_ipl的文件夹删除掉，因为没有用到。5：进入nand_spl/board，把除samsung外全部文件删除掉。6：再进入arch/arm/cpu文件夹，把除arm1176外其他文件夹删除掉。7：再进入arch/arm/include/asm文件夹，把除arch-s3c64xx文件外带arch-XX的文件夹删除8：再进入board/samsung文价夹下，把除smdk6400外其他文价夹删除掉。至此已经把没用到或者不想见到它的文件夹跟文件删除掉了。爽吧。二：1：在顶层的目录下找到Makefile文件，并且打开，因为vi或者vim没用习惯而是改用gedit。lwflwf-desktop:/home/u-boot-2010.12$ sudo gedit Makefile在这个Makefile你会找到：# ARM1176 Systems#smdk6400_noUSB_configsmdk6400_config:unconfigmkdir -p $(obj)include $(obj)board/samsung/smdk6400mkdir -p $(obj)nand_spl/board/samsung/smdk6400echo #define CONFIG_NAND_U_BOOT $(obj)include/config.hecho CONFIG_NAND_U_BOOT = y $(obj)include/config.mkif -z $(findstring smdk6400_noUSB_config,$) ;
