Enumeration Type Documentation

OtaErr_t

enum OtaErr_t

The OTA API return status. OTA agent error codes are in the upper 8 bits of the 32 bit OTA error word, OtaErr_t.

Enumerator
OtaErrNone	No error occurred during the operation.
OtaErrUninitialized	The error code has not yet been set by a logic path.
OtaErrPanic	Unrecoverable Firmware error. Probably should log error and reboot.
OtaErrInvalidArg	API called with invalid argument.
OtaErrAgentStopped	Returned when operations are performed that requires OTA Agent running & its stopped.
OtaErrSignalEventFailed	Failed to send event to OTA state machine.
OtaErrRequestJobFailed	Failed to request the job document.
OtaErrInitFileTransferFailed	Failed to update the OTA job status.
OtaErrRequestFileBlockFailed	Failed to request file block.
OtaErrCleanupControlFailed	Failed to clean up the control plane.
OtaErrCleanupDataFailed	Failed to clean up the data plane.
OtaErrUpdateJobStatusFailed	Failed to update the OTA job status.
OtaErrJobParserError	An error occurred during job document parsing. See reason sub-code.
OtaErrInvalidDataProtocol	Job does not have a valid protocol for data transfer.
OtaErrMomentumAbort	Too many OTA stream requests without any response.
OtaErrDowngradeNotAllowed	Firmware version is older than the previous version.
OtaErrSameFirmwareVersion	Firmware version is the same as previous. New firmware could have failed to commit.
OtaErrImageStateMismatch	The OTA job was in Self Test but the platform image state was not. Possible tampering.
OtaErrNoActiveJob	Attempt to set final image state without an active job.
OtaErrUserAbort	User aborted the active OTA.
OtaErrFailedToEncodeCbor	Failed to encode CBOR object for requesting data block from streaming service.
OtaErrFailedToDecodeCbor	Failed to decode CBOR object from streaming service response.
OtaErrActivateFailed	Failed to activate the new image.

OtaState_t

enum OtaState_t

OTA Agent states.

The current state of the OTA Task (OTA Agent).

Note

There is currently support only for a single OTA context.

OtaJobEvent_t

enum OtaJobEvent_t

OTA Job callback events.

After an OTA update image is received and authenticated, the agent calls the user callback (set with the OTA_Init API) with the value OtaJobEventActivate to signal that the device must be rebooted to activate the new image. When the device boots, if the OTA job status is in self test mode, the agent calls the user callback with the value OtaJobEventStartTest, signaling that any additional self tests should be performed.

If the OTA receive fails for any reason, the agent calls the user callback with the value OtaJobEventFail instead to allow the user to log the failure and take any action deemed appropriate by the user code.

See the OtaImageState_t type for more information.

Enumerator
OtaJobEventActivate	OTA receive is authenticated and ready to activate.
OtaJobEventFail	OTA receive failed. Unable to use this update.
OtaJobEventStartTest	OTA job is now in self test, perform user tests.
OtaJobEventProcessed	OTA event queued by OTA_SignalEvent is processed.
OtaJobEventSelfTestFailed	OTA self-test failed for current job.
OtaJobEventParseCustomJob	OTA event for parsing custom job document.
OtaJobEventReceivedJob	OTA event when a new valid AFT-OTA job is received.
OtaJobEventUpdateComplete	OTA event when the update is completed.

OtaHttpStatus_t

enum OtaHttpStatus_t

The OTA HTTP interface return status.

Enumerator
OtaHttpSuccess	OTA HTTP interface success.
OtaHttpInitFailed	Error initializing the HTTP connection.
OtaHttpDeinitFailed	Error deinitializing the HTTP connection.
OtaHttpRequestFailed	Error sending the HTTP request.

OtaMqttStatus_t

enum OtaMqttStatus_t

The OTA MQTT interface return status.

Enumerator
OtaMqttSuccess	OTA MQTT interface success.
OtaMqttPublishFailed	Attempt to publish a MQTT message failed.
OtaMqttSubscribeFailed	Failed to subscribe to a topic.
OtaMqttUnsubscribeFailed	Failed to unsubscribe from a topic.

OtaOsStatus_t

enum OtaOsStatus_t

The OTA OS interface return status.

Enumerator
OtaOsSuccess	OTA OS interface success.
OtaOsEventQueueCreateFailed	Failed to create the event queue.
OtaOsEventQueueSendFailed	Posting event message to the event queue failed.
OtaOsEventQueueReceiveFailed	Failed to receive from the event queue.
OtaOsEventQueueDeleteFailed	Failed to delete the event queue.

OtaOsTimerStartFailed	Failed to create the timer.
OtaOsTimerRestartFailed	Failed to restart the timer.
OtaOsTimerStopFailed	Failed to stop the timer.
OtaOsTimerDeleteFailed	Failed to delete the timer.

OtaPalMainStatus_t

enum OtaPalMainStatus_t

The OTA platform interface main status.

Enumerator
OtaPalSuccess	OTA platform interface success.
OtaPalUninitialized	Result is not yet initialized from PAL.
OtaPalOutOfMemory	Out of memory.
OtaPalNullFileContext	The PAL is called with a NULL file context.
OtaPalSignatureCheckFailed	The signature check failed for the specified file.
OtaPalRxFileCreateFailed	The PAL failed to create the OTA receive file.
OtaPalRxFileTooLarge	The OTA receive file is too big for the platform to support.
OtaPalBootInfoCreateFailed	The PAL failed to create the OTA boot info file.
OtaPalBadSignerCert	The signer certificate was not readable or zero length.
OtaPalBadImageState	The specified OTA image state was out of range.
OtaPalAbortFailed	Error trying to abort the OTA.
OtaPalRejectFailed	Error trying to reject the OTA image.
OtaPalCommitFailed	The acceptance commit of the new OTA image failed.
OtaPalActivateFailed	The activation of the new OTA image failed.
OtaPalFileAbort	Error in low level file abort.
OtaPalFileClose	Error in low level file close.

OtaImageState_t

enum OtaImageState_t

OTA Image states.

After an OTA update image is received and authenticated, it is logically moved to the Self Test state by the OTA agent pending final acceptance. After the image is activated and tested by your user code, you should put it into either the Accepted or Rejected state by calling OTA_SetImageState ( OtaImageStateAccepted ) or OTA_SetImageState ( OtaImageStateRejected ). If the image is accepted, it becomes the main firmware image to be booted from then on. If it is rejected, the image is no longer valid and shall not be used, reverting to the last known good image.

If you want to abort an active OTA transfer, you may do so by calling the API OTA_SetImageState ( OtaImageStateAborted ).

Enumerator
OtaImageStateUnknown	The initial state of the OTA MCU Image.
OtaImageStateTesting	The state of the OTA MCU Image post successful download and reboot.
OtaImageStateAccepted	The state of the OTA MCU Image post successful download and successful self_test.
OtaImageStateRejected	The state of the OTA MCU Image when the job has been rejected.
OtaImageStateAborted	The state of the OTA MCU Image after a timeout publish to the stream request fails. Also if the OTA MCU image is aborted in the middle of a stream.

OtaPalImageState_t

enum OtaPalImageState_t

OTA Platform Image State.

The image state set by platform implementation.

Enumerator
