This section introduces the FOTA interface APIs including terms and acronyms, supported features, software architecture, details on how to use this interface, FOTA function groups, enums, structures and functions.
This interface writes into a pre-defined register flag. The bootloader enters the update process based on the value written in the flag. The return error code indicates if the flag is written successfully or not. After the update is complete, the UA automatically resets the register flag. Note, it is recommended to call the reboot API after calling the FOTA interface, because fota_trigger_update() does not contain reboot functionality. There is no dedicated FOTA read or write SDK API, it is suggested to use HAL flash SDK API to write data to specified address of flash. Regarding to the FOTA update flow & usage, please refer to the Firmware Update Developers Guide located under [sdk_root]/doc folder.
|FOTA||Firmware Over-The-Air (FOTA) is a Mobile Software Management technology in which the operating firmware of a mobile device is wirelessly upgraded and updated by its manufacturer. Please refer to FOTA in Techopedia.|
|UA||Update Agent performs the actual FOTA update on devices. It operates as stand-alone application in bootloader and replaces the old firmware with the new one.|
|TFTP||Trivial File Transfer Protocol (TFTP) is a simple, lockstep, File Transfer Protocol which allows a client to get from or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a local area network. For an introduction to TFTP, please refer to TFTP in Wikipedia.|
MediaTek MT2523 provides a reference design using FOTA package downloads. The supporting connectivity between Android application package and MT2523 HDK is Bluetooth. It enables transferring packages from the file system of smartphones over FOTA to the MT2523 HDK. Then MT2523 device writes the data from the file to the specified, pre-defined partition.
