   13  * @page c_fwupdate Firmware Update API
   14  *
   15  * @ref le_fwupdate_interface.h "API Reference"
   16  *
   17  * <HR>
   18  *
   19  * Firmware update allows the various firmware images to be updated from the application processor.
   20  * This may include the modem bootloader, modem firmware, and linux image, where the linux image
   21  * consists of the linux bootloader, linux kernel, and linux rootfs.
   22  *
   23  * Firmware update is useful when the image comes from an alternative source, rather than as an
   24  * over-the-air update through the AirVantage service.
   25  *
   26  * @section le_fwupdate_binding IPC interfaces binding
   27  *
   28  * All the functions of this API are provided by the @b le_fwupdate service.
   29  *
   30  * Here's a code sample binding to the le_fwupdate service:
   31  * @verbatim
   32    bindings:
   33    {
   34       clientExe.clientComponent.le_fwupdate -> fwupdateService.le_fwupdate
   35    }
   36    @endverbatim
   37  *
   38  *
   39  * @warning All of these APIs are not available for all platforms. Please refer to the
   40  * Product Technical specification document of your platform for further details.
   41  * Please refer to @subpage platformConstraintsDualSys for details on Dual System.
   42  *
   43  * @section le_fwupdate_image Update Firmware Image
   44  *
   45  * The firmware update process is started by calling le_fwupdate_Download().  This function takes
   46  * a file descriptor, rather than a file, to provide flexibility in the source of the image.  In
   47  * particular, this can be used to stream the image, rather than having to save it on the file
   48  * system before doing the update.
   49  *
   50  * On platform which does not support dual system, when the image is successfully downloaded, a
   51  * reset will occur in order to apply the update. This will reset all processors.  After the
   52  * application processor has restarted, the @ref le_info_version APIs can be used to determine
   53  * whether the firmware has been updated to the new version.
   54  *
   55  * On platform which supports dual system, if the image is successfully downloaded, the user needs
   56  * to swap the systems in order to use the updated system. This will reset all processors. After the
   57  * application processor has restarted, the @ref le_info_version APIs can be used to determine
   58  * whether the firmware has been updated to the new version.
   59  *
   60  * @section le_fwupdate_resume Update Firmware Image Download Resume
   61  *
   62  * During the download, the flash programming position is saved. Thanks to this position, fwupdate
   63  * service is able to resume the download without downloading the update package at the beginning.
   64  *
   65  * By default, the fwupdate service download API is resuming the previous download: new data
   66  * received through this API will be programmed at the resume position.
   67  *
   68  * @note
   69  * A download can be resumed when:
   70  * - le_fwupdate_Download() API has previously returned LE_CLOSED or LE_TIMEOUT
   71  * - A reset occured during last le_fwupdate_Download() processing (Legato/full system reset)
   72  * - No resume can be performed in other cases.
   73  *
   74  * A complete download can be forced by calling le_fwupdate_InitDownload(). Resume position
   75  * is set to 0.
   76  *
   77  * The current resume position can be retrieved by calling le_fwupdate_GetResumePosition().
