關(guān)閉Linux串口調(diào)試

關(guān)閉Linux串口的調(diào)試功能一直以來，我們都習(xí)慣使用Linux串口登陸Linux控制臺，但一般開發(fā)板一般是只有一個串口的，但是我們有時候會使用串口進(jìn)行正常的通信，而Linux控制臺默認(rèn)占用了該串口，導(dǎo)致不能應(yīng)用程序使用該串口，所以我們有必要釋放串口。下面以O(shè)K6410為例，飛凌6410的Linux源碼存放在\Linux-3.0.1\kernel_sourcecode\T，將源碼的壓縮包拖放到虛擬機(jī)的Linux，打開終端,tarxvzflinux-3.0.1-v7.40-2014-09-13.tar.gz解壓該壓縮包。1.切換root身份，改變工作目錄為Linux所在的目錄，執(zhí)行makemenuconfig，進(jìn)入內(nèi)核配置選項2.選擇DeviceDrivers->Characterdevices->Serialdrivers->SupportforconsoleonSamsungSocserialport,按N取消該項，選擇EXIT退出并保存設(shè)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消該項，選擇EXIT退出并保存設(shè)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頃上展(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終端 文件(F)編輯(E)查看(V)搜索(S)終端⑴幫助(H)終端 文件(F)編輯(E)查看(V)搜索⑶終端(T)幫助(H)[扁.L'K*.root{3>dzxxgc-vm:/home/dzxxgc/M面/Linux/linux-3.0.1.config-Ltnux/arm3.0.1KernelConfigurationuartLinux終端文件(F)編輯(E)查看(V)搜索⑸終端終端文件(F)編輯(E)查看(V)搜索⑸終端(T)幫助(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>陶畫▽書)22:53±dzxxgc{>Serialdrivers[1終端 文件(F)編輯舊查看(V)搜索陶畫▽書)22:53±dzxxgc{>Serialdrivers[1終端 文件(F)編輯舊查看(V)搜索(S)終端(T)幫助(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/如凱viitueldevtcesupportRMJTAGDCCc
