uboot中make menuconfig以及添加命令

1. make menuconfig：与make config一样，只不过是图形界面而已，需要安装ncurses。

2. make menuconfig中的menuconfig与all，clean一样，是目标。自己的uboot（简称uboot2011）中的menuconfig目标下面有一行：$(SHELL) $(SCRIPTSDIR)/Menuconfig config.in。表示使用脚本文件夹下的Menuconfig来解释本目录的config.in。本目录的config.in下面最后有：

if [ "$CONFIG_RTL838X" = "y" ] || [ "$CONFIG_RTL838XS" = "y" ]; then

source ./board/Realtek/rtl838x/menuconfig.in

elif [ "$CONFIG_RTL839X" = "y" ] || [ "$CONFIG_RTL839XS" = "y" ]; then

source ./board/Realtek/rtl839x/menuconfig.in

fi

这样就找到了其实最后诊断那个目录是在。。。地方。然后依照示例加一行就ok。

3. 我加了bool 'My Test' CONFIG_MY_TEST，这样会在autoconfig.h中出现宏CONFIG_MY_TEST=1，然后再通过这个宏切uboot中自定义的命令就好。

4. 照着CONFIG_CMD_FLASH_TEST来添加：

Autoconf.h (include\configs):#define CONFIG_CMD_FLASH_TEST 1

Board_cmd.c (8x):#ifdef CONFIG_CMD_FLASH_TEST

Board_cmd.c (8x):#ifdef CONFIG_CMD_FLASH_TEST

Board_cmd.c (8x):#ifdef CONFIG_CMD_FLASH_TEST

Board_cmd.c 9x):#ifdef CONFIG_CMD_FLASH_TEST

Board_cmd.c 9x):#ifdef CONFIG_CMD_FLASH_TEST

Board_cmd.c 9x):#ifdef CONFIG_CMD_FLASH_TEST

8x.h (include\configs):#if defined(CONFIG_CMD_FLASH_TEST) //CONFIG_SYS_POST_FLASH will use flash test

8x.h (include\configs):#define CONFIG_CMD_FLASH_TEST 1

8xS.h (include\configs):#if defined(CONFIG_CMD_FLASH_TEST) //CONFIG_SYS_POST_FLASH will use flash test

8xS.h (include\configs):#define CONFIG_CMD_FLASH_TEST 1

9x.h (include\configs):#if defined(CONFIG_CMD_FLASH_TEST) //CONFIG_SYS_POST_FLASH will use flash test

9x.h (include\configs):#define CONFIG_CMD_FLASH_TEST 1

9xS.h (include\configs):#if defined(CONFIG_CMD_FLASH_TEST) //CONFIG_SYS_POST_FLASH will use flash test

9xS.h (include\configs):#define CONFIG_CMD_FLASH_TEST 1
