AutomaticconfigurationandrecommenderrolesTwomainroles:◦ manageHWmodularity;◦ contributemanaginggatewaydeployment.

ManageHWmodularity:dependingontheHWmodulesconnectedtothegatewayautomaticallyconfigurethedrivers;selectandconfigurethecorrespondingAGILEmodules.Managegatewaydeployment:thegatewaycanbedeployedindifferentcontexts,bothintermsofenvironmentandverticalapplication.Thegatewayprovidetotherecommenderinformationaboutthedeploymentcontext,therecommenderselectaconfiguration/sdependingonthecontextandsendit/themtotheautoconfig thatinturnsappliestheconfiguration.Whatistherelation betweentheautoconfig andtherecommender?◦ Therecommendersuggestsasetofsolutions toaconfiguration issue.◦ Theautoconfig selectsoneofthesuggestedsolutionsandappliesit.

RolesoftherecommenderRoleoftherecommender:◦ recommendsapplications andworkflows;◦ recommendsconfigurations;◦ recommendsperipherals(tobediscussed).

Atboot:◦ fordevicedriversitisalreadyprovidedbytheOS;◦ attheendofthebootprocess,afterenteringtheuserspace,theAGILESWModulesareautomaticallyconfiguredbyautoconfig.(thisisdonebyConfigurator)

Atruntime:configuresdriversandAGILEModules.◦ Rpi Shieldscurrentlydoesn’t supporthotplug/swap.Itispossible tosupport itwithspecifichardwaremodificationoftheShield(basedonabuffertomanagethesignalsduringhotplug/swap),passingUART,I2C,etc.through theshieldandmonitoring withadaemonaspecificI/Oline;

◦ alwayssupportedbyperipheralsbasedonenumerableinterfaces(USB,Bluetooth,etc..).

◦ ExceptforUSB,theindustrialgatewaydoesn’tneedhotswapperipherals,thereforeitdoesn’tneedauto-configurationatruntime.
