    Hi Natesh,

    Have you tried going through our SimpleLink academy to learn about the OTA example? Going through this tutorial will answer your questions.

    Hi Kannannatesh,

    I'm not sure i understand your problem.

    The trigger for starting the OTA procedure (i.e. looking for new update in the server) is external and is up to you, The example requires user interface (e.g. pressing a button), but you can implement something else such as timer based polling or waiting for a-sync notification (e.g. through MQTT).

    I wasn't able to understand if you ran the OTA successfully for the first time and asking about the OTA triggering with the new image or if you have more fundamental issue with the OTA activation. Please describe exactly what is working and what needs to be solved.

    Hi,

    Why are you using the Energia and not the SDK?

    Are you using the OTA library from the SDK?

    After you download and install the new OTA image, once the new image starts running successfully, it should commit  the loaded bundle (before the next reset): see code (form the library) below. 

    int16_t OtaArchive_commit()
    {

    SlFsControl_t FsControl;
    int16_t Status;

    FsControl.IncludeFilters = 0;
    Status = (int16_t)sl_FsCtl(SL_FS_CTL_BUNDLE_COMMIT, 0, NULL ,(uint8_t *)&FsControl, sizeof(SlFsControl_t), NULL, 0 , NULL);
    if( 0 > Status )
    {

    _SlOtaLibTrace(("OtaArchive_Commit: ERROR sl_FsCtl, Status=%d\r\n", Status));

    }
    return Status;

    }

    If you set the /sys/mcubootinfo.bin and create a watchdog timeout  (for 5 minutes?) - the device will automatically reset itself if there was no commit (w/d stop).

    Please refer to the OTA training for more details.
