开始教程之前.你需要下载源码,解压....此处略过千万行~~源码为uboot2010.03这个..别整错了.错了也没事,都差不多~

这里,我们直接打开Makefile,找到smdk6400_config,根据6400 添加6410 的目标......如下:

#########################################################################

## ARM1176 Systems

#########################################################################

smdk6400_noUSB_config \

smdk6400_config : unconfig

@mkdir -p $(obj)include $(obj)board/samsung/smdk6400

@mkdir -p $(obj)nand_spl/board/samsung/smdk6400

@echo "#define CONFIG_NAND_U_BOOT" > $(obj)include/config.h

@if [ -z "$(findstring smdk6400_noUSB_config,$@)" ]; then \

echo "RAM_TEXT = 0x57e00000" >> $(obj)board/samsung/smdk6400/config.tmp;\

$(MKCONFIG) $(@:_config=) arm arm1176 smdk6400 samsung s3c64xx; \

else \

echo "RAM_TEXT = 0xc7e00000" >> $(obj)board/samsung/smdk6400/config.tmp;\

$(MKCONFIG) $(@:_noUSB_config=) arm arm1176 smdk6400 samsung s3c64xx; \

fi

@echo "CONFIG_NAND_U_BOOT = y" >> $(obj)include/config.mk

smdk6410_noUSB_config \

smdk6410_config : unconfig

@mkdir -p $(obj)include $(obj)board/samsung/smdk6410

@mkdir -p $(obj)nand_spl/board/samsung/smdk6410

@echo "#define CONFIG_NAND_U_BOOT" > $(obj)include/config.h

@if [ -z "$(findstring smdk6400_noUSB_config,$@)" ]; then \

echo "RAM_TEXT = 0x57e00000" >> $(obj)board/samsung/smdk6410/config.tmp;\

$(MKCONFIG) $(@:_config=) arm arm1176 smdk6410 samsung s3c64xx; \

else \

echo "RAM_TEXT = 0xc7e00000" >> $(obj)board/samsung/smdk6410/config.tmp;\

$(MKCONFIG) $(@:_noUSB_config=) arm arm1176 smdk6410 samsung s3c64xx; \

fi

@echo "CONFIG_NAND_U_BOOT = y" >> $(obj)include/config.mk

接着修改交叉编译器:

# set default to nothing for native builds

ifeq ($(HOSTARCH),$(ARCH))

CROSS_COMPILE ?= arm-linux-

endif
