怎样编写menuconfig代码(基于安霸平台).docx

menuconfig配置功能的代码编写 -基于安霸平台语法一：choice(prompt/default/help)config(bool/help)endchoice1.1使用范例1.1：/*语法一：choiceconfigenchoice*start*/Choice -menuconfig界面直接就是列表显示模式。prompt Preference to Compile/Link ARM/THUMB codedefault PREFER_CORE_ARMhelp -帮助说明信息The ARM core on the Ambarella Processor can executeeither ARM or THUMB instructions. There are variouslibraries that are distributed in either ARM or THUMB versions.Choosing this parameter can change the compiling and linkingbehavior to use either ARM/THUMB versions wherever applicable.config PREFER_CORE_ARM-将来用来宏定义控制程序编译的标志bool ARM-menuconfig菜单显示的 布尔型标志（只能Y or N）config PREFER_CORE_THUMBbool THUMB -由于此处代码未加help信息，所以机器的提示为默认信息endchoice/*语法一：choiceconfigenchoice*end*/1.2使用范例1.1对应的menuconfig界面显示。选择型的选择值 语法二：menu(comment/depend on)config(bool/default/depend on/help)endmenu2.1 使用范例2.1menu Audio modulecomment WARNING: CHANGING FOLLOWING PARAMETERS HAS NO EFFECT! (no source) -菜单也可以由警告信息。depends on !has_audio_srcconfig ENABLE_AUDIObool Enable Audio moduledefault nhelpThis option will enable the audio module to comperss and decompress audio.config ENABLE_TEST_AUDIObool Run the AUDIO infrastructure Test program default ndepends on ENABLE_TESTdepends on ENABLE_AUDIO-因为此菜单项代码是同级别的，所以当开启ENABLE_AUDIO条件，菜单显示是同级的。helpThis test simulates a AUDIO infrastructure running schemeconfig ENABLE_AUDIO_QUALbool Run the AUDIO Signal Qual program default ndepends on ENABLE_TESTdepends on ENABLE_AUDIO-因为此菜单项代码是同级别的，所以当开启ENABLE_AUDIO条件，菜单显示是同级的。helpThis provides a series of AUDIO Signal Qual Programsconfig ENABLE_AUDIO_2bool Enable Audio module V2.省略endmenu2.2使用范例2.1对应的menuconfig界面显示。 三、衍生的语法应用3.1 十六进制型 menu AMBoot memory optionsconfig AMBOOT_BLD_RAM_STARThex AMBoot bootloader starting address -此处非bool型的数据，而是hex（十六进制）default 0xc0000000 -默认的数值helpThe AMBoot bootloader starting address - The bootloader code isthe 2nd-stage code that is loaded by the AMBoot bootstrappercode. Its size is limited to 64KB in size. It contains aninteractive prompt, diagnostics, and utilities for managingthe flash contents as well as loading other (RTOS, ramdisk,etc.) images into the DRAM and uncompressing and executingthem. (Please dont modify this value unless you know whatyou are doing!).省略endmenu3.2 字符串型_1输入字符参数menu AMBoot (boot loader).省略config AMBOOT_DEV_CMDLINEstring Booting parameter (cmdline)default helpEnter the booting parameter command line here. Note: the valueselected under this option will be the default programmedinto flash, but could be later modified interactively at theAMBoot command prompt.省略endmenu3.3 字符串型_2 （字符串依赖型）menu ROMFS Partitiondepends on BUILD_DEVFWconfig CREATE_ROMFS_FWbool Create ROMFS firmware from binariesdefault ndepends on (ENABLE_FLASH & BUILD_DEVFW)helpSelect this option if you want to create ROMFS firmeareusing the ROMFS generator.config ROMFS_CONFIG_FILEstring ROMFS config filedefault depends on (BUILD_DEVFW & CREATE_ROMFS_FW)helpLocation of the ROMFS config file or shellscirpt to generate the specified ROMFS config file.config ROMFSstring ROMFS imagedefault depends on (BUILD_DEVFW & !CREATE_ROMFS_FW)helpLocation of the ROMFS image.config ROMFS_VIFstring ROMFS Version Filedefault depends on BUILD_DEVFWhelpLocation of the version description file that describesthe format of the ROMFS image.endmenu四、choice endchoice 与 menu endmenu的区别4.1
