关闭Linux串口调试

关闭Linux串口的调试功能一直以来，我们都习惯使用Linux串口登陆Linux控制台，但一般开发板一般是只有一个串口的，但是我们有时候会使用串口进行正常的通信，而Linux控制台默认占用了该串口，导致不能应用程序使用该串口，所以我们有必要释放串口。下面以OK6410为例，飞凌6410的Linux源码存放在\Linux-3.0.1\kernel_sourcecode\T，将源码的压缩包拖放到虚拟机的Linux，打开终端,tarxvzflinux-3.0.1-v7.40-2014-09-13.tar.gz解压该压缩包。1.切换root身份，改变工作目录为Linux所在的目录，执行makemenuconfig，进入内核配置选项2.选择DeviceDrivers->Characterdevices->Serialdrivers->SupportforconsoleonSamsungSocserialport,按N取消该项，选择EXIT退出并保存设置。PatchLTnux/am3.8.1KernelConftgura±i.onArrowkeysnavigatethemenu.<Enter>selectssubmenus—Highlightedlettersarehotkeys.Pressing<¥>includes,<N>excludes,<M>modularizesfeatures.Press<Esc;*<Esc=*toexitj<?>forHelp,</=*forSearch.Legend:[*]built-in[]excluded<M>module<>modul_etiesystems—>Iernelhacking---aecurityoptions消该项，选择EXIT退出并保存设置。PatchLTnux/am3.8.1KernelConftgura±i.onArrowkeysnavigatethemenu.<Enter>selectssubmenus—Highlightedlettersarehotkeys.Pressing<¥>includes,<N>excludes,<M>modularizesfeatures.Press<Esc;*<Esc=*toexitj<?>forHelp,</=*forSearch.Legend:[*]built-in[]excluded<M>module<>modul_etiesystems—>Iernelhacking---aecurityoptions—>ryptographicAPI——>PHPowerManagement——>loatingpointemulation-serspacebinaryformats-owermanagementoptions--*-N'twMkingsupport——><Exit> <Help■>Ltnux/arn3.0.1KernelConftgurattonArrowkeysnavigatethemenu.<Enter>selectssubmenus—>.Highlightedlettersarehotkeys.Pressing<¥>includes,<N>excludes,<M>modularizesfeatures.Press<Esc><Esc>toexit,<?>forHelp,</>forSearch.Legend:[*]built-in[]excluded<M>module<>modulecapable<Exit> <HelpaGeneralsetup—>[*]nableloadablemodulesupportEnabletheblocklayer—>SystemType—>ussupport—>KernelFeatures—?Bootoptions—>CPUPowerManagement——>loatingpointemulation——>VM)))22:51±dzxxgc{>tovirtualtranslatxons顷上展(EXPERIMENTAL)DeviceDrivers<Select>段既▽引》22:52±dzxxgc{>root@}dzxxgc-vm:/home/dzxxgc/M面/Linux/linux-3,0,1.confi.g-Linux/am3.0.1KernelConfiguration终端 文件(F)编辑(E)查看(V)搜索(S)终端⑴帮助(H)终端 文件(F)编辑(E)查看(V)搜索⑶终端(T)帮助(H)[扁.L'K*.root{3>dzxxgc-vm:/home/dzxxgc/M面/Linux/linux-3.0.1.config-Ltnux/arm3.0.1KernelConfigurationuartLinux终端文件(F)编辑(E)查看(V)搜索⑸终端终端文件(F)编辑(E)查看(V)搜索⑸终端(T)帮助(H)V4必22:53±dzxxgc{>.config-Linux/arm3.0.1KernelConfigurationArrowkeysnavigatethemenu.<Enter>selectssubmenus——>.Highlightedlettersarehotkeys.Pressing<¥>includes,<N>excludes,<M>modularizesfeatures.Press<Esc><Esc>toexit,<?>forHelp,</>forSearch*Legend:[*]built-in[]excludedmodule<>module[]Multipledevicesdriversupport(RAIDandLVM)——>>GenericTargetCoreMod(TCM)andConfigFSInfrastructure——[*]Networkdevicesupport——>[]ISDNsupport——>>Telephonysupport——><*>I2Csupport——>[*]<*>I2Csupport——>[*]SPIsupport——><Exit> <Help>陶画▽书)22:53±dzxxgc{>Serialdrivers[1终端 文件(F)编辑旧查看(V)搜索陶画▽书)22:53±dzxxgc{>Serialdrivers[1终端 文件(F)编辑旧查看(V)搜索(S)终端(T)帮助(H)CharacterdevicesArrowkeysnavigatethemenu.<Enter>selectssubmenus—>.Highlightedlettersarehotkeys.Pressing<Y>includes,<N>excludes,<M>modularizesfeatures.Press<Esc;*<Esc>toexit,<?>forHelp,</=*forSearch.Legend:[*]built-in[]excluded<M>module<>moduleupportforbindingandunbindingconsoledriversnix98PTYsupportupportmultipleinstancesofdevptsegacy(BSD)PTYsupportNn-standardserial.po「tsupportSMMUXlinedisciplinesupport(EXPERIMENTAL)racedatasinkforMIPIP1149,7cJTAGstandardRMJTAGDCCconsolei改/如凯viitueldevtcesupportRMJTAGDCCc
