   13  * @page c_le_dualsys Dual Systems Update API
   14  *
   15  * @ref le_dualsys_interface.h "API Reference"
   16  *
   17  *
   18  * Dual systems are systems composed with two set of partitions: one is said "ACTIVE", so currently
   19  * in use, and the other said "UPDATE", so not used but ready-to-use.
   20  *
   21  * On dual systems, when Legato updates an image through the le_fwupdate API, it works on the
   22  * UPDATE system.
   23  * And then an "install" command performs a switch from UPDATE to ACTIVE after a reboot:
   24  * The new ACTIVE system is used. The UPDATE partition becomes ready for a new update or for
   25  * roll-back if the new ACTIVE fails to start properly.
   26  *
   27  * In each set, three sub-systems are defined:
   28  *     - The "modem" group for all binaries and filesystem related to modem core,
   29  *     - The "lk" group for the LK bootloader,
   30  *     - The "linux" group the kernel, rootfs and legato partitions.
   31  *
   32  * @section le_dualsys_binding IPC interfaces binding
   33  *
   34  * All the functions of this API are provided by the @b le_dualsys service.
   35  *
   36  * Here's a code sample binding to the le_dualsys service:
   37  * @verbatim
   38    bindings:
   39    {
   40       clientExe.clientComponent.le_dualsys -> fwupdateService.le_dualsys
   41    }
   42    @endverbatim
   43  *
   44  *
   45  * @warning All of these APIs are only available for all dual systems platforms. Please refer
   46  * to the Product Technical Specification document of your platform for further details.
   47  * Please refer to @subpage platformConstraintsFwUpdate for details.
   48  *
   49  * @section le_dualsys_DisableSyncBeforeUpdate Disable the check of sync before updating
   50  *
   51  * It is possible to force the update of any partition even if the systems are not synchronized.
   52  * This is done by calling le_fwupdate_DisableSyncBeforeUpdate() with the value true. If the value
   53  * is false, the synchronization will be mandatory before performing an update.
   54  * Note that the synchronization is automatically done by calling the function
   55  * le_fwupdate_InitDownload() when the synchronization check is enabled.
   56  *
   57  * @section le_dualsys_system Defining a System
   58  *
   59  * It is possible to define a system by calling le_dualsys_SetSystem().  This function takes
   60  * three values, one for the modem sub-system, one for the lk sub-system and one for the linux
   61  * sub-system.  The values are one of 0 for system 1 or 1 for system 2.  When set, the system will
   62  * be usable after the next reset.
   63  * If no error is encountered, this function will perform a reset.
   64  *
   65  * It is possible the get the last defined system by calling the le_dualsys_GetSystem().  This
   66  * function returns the values for the three sub-systems.  This system is updated accordingly
   67  * the last system set by le_dualsys_SetSystem().
   68  *
   69  * It is possible to get the current active system by calling le_dualsys_GetCurrentSystem().
   70  * This function returns the values for the three sub-systems.  If le_dualsys_SetSystem() is
   71  * called before le_dualsys_GetCurrentSystem(), the returned values may differ as they represent
   72  * the current system in use.
