2.Deploydevelopmentenvironment
Beforethedevelopment,youneedtoinstalltheLinuxoperatingsystemonthePC.ItisrecommendedtousetheUbuntu16.04
64bitdistribution,8Gmemory,andmorethan500Gfreeharddisk.Connectthenetworkcableandconfigurethenetwork.For
subsequentoperations,youneedtoconnecttotheInternettoinstallordownloadrelatedsoftwarepackages.
YoucanalsorefertotheofficialNXPdocument<Android_User's_Guide.pdf>.
RepalcetheUbuntusources-list
Noticethatthisonlyappliestothedeveloperinchina.Ifyouareinchina,thetunaresourceshouldinsteadofthedefault.
Thewebsiteisasfollows：
https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
Choose16.04，andthencopythecontentstoupdate/etc/apt/source.list.
Operatingprocedures：
1.Backupthedefaultfile
cp/etc/apt/sources.list/etc/apt/sources.list-bak
2.Copycontentsfromthetuna16.04columnto/etc/apt/sources.listfile.
3.Updatesource
apt-getupdate
PS:Iferrorhappenstoappstream3,youcanremovethepackagefirstandthenupdate.
apt-getremovelibappstream3
apt-getupdate
Hostpackages
EssentialYoctoProjecthostpackagesare:

Setrepofile
Therepofileisusedtodownloadresources,anditislocatedin03-Tools/Repoforchinese,itshouldbeinstalledonyourcomputer
byperformingthesestep:
mkdir~/bin
cp~/03-Tools/Repo/repo~/bin
chmoda+x~/bin/repo
exportPATH=~/bin:$PATH
Pleasefollowbelowstepsinsteadofabove,ifyouareabletoaccessgoogle.

3.Androidsystemprogramandcompile
Androidimagecompilationtakesalongtime,youcanusethecompiledimagetoprogramtothedevelopmentboard,useUUU
toolstoprogram.ThischapterfirstdescribeshowtoprogramimagestoEMMCandSDcards,andthenintroducesthemethodof
compilingimages.

4.1DM-verityconfiguration
DM-verity(device-mapper-verity)providestransparentintegritycheckingofblockdevices.Itcanpreventdevicefromrunning
unauthorizedimages.Thisfeatureisenabledbydefault.Replacingoneormorepartitions(boot,vendor,system,vbmeta)will
maketheboardunbootable.DisablingDM-verityprovidesconviencefordevelopers,butthedeviceisunprotected.
TodisableDM-verity,performthefollowingsteps:
1. setting->system->abouttabletclickbuildnumbertoopendevelopmentoptions
2. setting->system->developeroptionsenableOEMunlocking
