The software loading process may be controlled using this object. Setting the value load(1) will begin transfer of the specified file from the external URI to the unit. If the file is a manifest, this will initiate transfer of all referenced files. When this procedure has completed, aviatSmLoadStatus will indicate loadOk(6) for success, or loadError(10) for failure. An unresolvable incompatibility error is indicated by compatibilityError(13) and should be followed by an abort(0). A successful software (loadOk) load may be activated by setting the value to activate(2). If the delayed/timed activation objects are disabled this will have an immediate effect, otherwise the activation will take place as scheduled. A successful activation will result in an aviatSmLoadStatus value of activateOk(7). An error will be indicated by the value activateError(11). If the value is idle(7) and no software load process has been initiated since the last successful activation, the inactive software can be re-activated by setting the value to rollback(4). Success is indicated in aviatSmLoadStatus by rollbackOk(8) and failure by rollbackError(12). Setting the value to loadAndActivate(3) will begin software transfer. A successful transfer will be followed by software activation which is controlled by the delayed/timed activation objects. Success will be indicated in aviatSmLoadStatus by activateOk(7). A pending scheduled activation is indicated by waitingToActivate(13).
