This section briefs how to add a new component along with TR-181 data models to RDK-B.<\/strong><\/p>\n\n\n\n

Test Component API List<\/h4>\n\n\n\n
TestComponent_GetParamUlongValue<\/td> API is used to retrieve the parameter value of type \u201cunsignedInt\u201d<\/td><\/tr>
TestComponent_SetParamUlongValue<\/td>API is used to set the parameter value of type \u201cunsignedInt\u201d<\/td><\/tr>
TestComponent_GetParamStringValue <\/td>API is used to retrieve the parameter value of type \u201cstring\u201d<\/td><\/tr>
TestComponent_SetParamStringValue   <\/td>API is used to set the parameter value of type \u201cstring\u201d<\/td><\/tr>
TestComponent_Commit                       <\/td>To Commit all the update to the data model<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Build ccsp-testcomponent for Raspberry Pi device<\/h4>\n\n\n\n
    \n
  1. Put the\u00a0ccsp-testcomponent.bb<\/a>\u00a0recipe file inside meta-rdk-broadband\/recipes-ccsp\/ccsp\u00a0 location.<\/li>\n\n\n\n
  2. \u00a0Create folder names “files” under\u00a0 “meta-rdk-broadband\/recipes-ccsp\/ccsp” path<\/li>\n\n\n\n
  3. Put\u00a0CcspTestComponent.tar.gz<\/a>\u00a0(source code of TestComponent)\u00a0file inside meta-rdk-broadband\/recipes-ccsp\/ccsp\/files\u00a0 \u00a0location.<\/li>\n\n\n\n
  4. Build the test component inside build directory i.e. build-raspberrypi-rdk-broadband directory.
    bitbake ccsp-testcomponent<\/em><\/li>\n\n\n\n
  5. Binary file of test component will be present inside build-raspberrypi-rdk-broadband\/tmp\/work\/cortexa7hf-neon-vfpv4-rdk-linux-gnueabi\/ccsp-testcomponent\/1.0-r0\/image\/usr\/bin\/ location<\/li>\n\n\n\n
  6. XML file of test component will be present inside\u00a0
    build-raspberrypi-rdk-broadband\/tmp\/work\/cortexa7t2hf-neon-vfpv4-rdk-linux-gnueabi\/ccsp-testcomponent\/1.0-r0\/image\/usr\/ccsp\/testcomponent\/ location.<\/li>\n<\/ol>\n\n\n\n

    NOTE : For rpi4 , yocto 3.1 use ccsp_testcomponent.tar.gz<\/a> to avoid build errors due to cfg directory missing<\/p>\n\n\n\n

    Run the Test Component<\/h4>\n\n\n\n
    Copy the supported files to Raspberry Pi device<\/h5>\n\n\n\n

    Copy test_component (Binary of ccsp-testcomponent, generated in step 4 of Build) and TestComponent.xml (present at location mentioned in step 5 of Build) to \/tmp\/ directory of Raspberry Pi device.<\/p>\n\n\n\n

    Execute the TestComponent in the Raspberry Pi device<\/h5>\n\n\n\n

    Go to \/tmp\/ directory of Raspberry Pi 3 and start the ccsp-testcomponent
    .\/test_component -subsys eRT.<\/em><\/p>\n\n\n\n

    You can check the status of the process by doing  ps <\/em>in the RPi device.<\/p>\n\n\n\n

    Validate if component is registered with CR<\/h5>\n\n\n\n

    DMCLI (Database Manager Command Line Interface) provides interface used to send and receive command\/messages via CLI (Command Line Interface) over Telnet and SSH protocols.<\/p>\n\n\n\n

    List all the test component parameters using dmcli:<\/p>\n\n\n\n

    dmcli eRT getv Device.TestComponent.<\/em><\/p>\n\n\n\n

    Expected Output:\nCR component name is: eRT.com.cisco.spvtg.ccsp.CR\nsubsystem_prefix eRT.\ngetv from\/to component(eRT.com.cisco.spvtg.ccsp.testcomponent): Device.TestComponent.\nExecution succeed.\nParameter    1 name: Device.TestComponent.TestSampleParamUlong\n               type:       uint,    value: 1<\/pre>\n\n\n\n
    Change the “TestSampleParamUlong” parameter value by using below command:<\/p>\n\n\n\n
    dmcli eRT setv Device.TestComponent.TestSampleParamUlong uint 5<\/em><\/p>\n\n\n\n
    Now verify the value by this command<\/p>\n\n\n\n
    dmcli eRT getv Device.TestComponent.TestSampleParamUlong<\/em><\/p>\n\n\n\n
    Include Newly Added Component in Package Group<\/h4>\n\n\n\n
    Once the validation is successfully done and we can now include the new component (ccsp-testcomponent) in the package groups.<\/p>\n\n\n\n
      \n
    1. \u00a0Open “packagegroup-rdk-ccsp-broadband.bb” file present at “meta-rdk\/recipes-core\/packagegroups\/packagegroup-rdk-ccsp-broadband.bb” location.<\/li>\n\n\n\n
    2. In the “RDEPENDS_packagegroup-rdk-ccsp-broadband” flag add the name of new component.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
