Enumerator
LT_OK	Operation was successful.
LT_FAIL	Operation was not successful.
LT_PARAM_ERR	Some parameter was not accepted by function.
LT_CRYPTO_ERR	Error detected during cryptographic operation.
LT_APP_FW_TOO_NEW	TROPIC01's Application FW is too new for the current version of Libtropic. Please update Libtropic to a newer release version.
LT_REBOOT_UNSUCCESSFUL	TROPIC01 executed the Startup_Req L2 Request (invoked by calling lt_reboot()) successfully, but the mode TROPIC01 is in after the reboot is not the expected one based on the startup_id argument: startup_id==TR01_REBOOT and TROPIC01's mode after successful reboot is not LT_TR01_APPLICATION (this can e.g. happen when the chip, for some reason, cannot execute the Application FW - it will stay in Start-up Mode no matter the startup_id), or startup_id==TR01_MAINTENANCE_REBOOT and TROPIC01's mode after successful reboot is not LT_TR01_MAINTENANCE.
LT_L1_SPI_ERROR	Some SPI related operation was not successful.
LT_L1_DATA_LEN_ERROR	Data does not have an expected length.
LT_L1_CHIP_STARTUP_MODE	Chip is in STARTUP mode.
LT_L1_CHIP_ALARM_MODE	Chip is in ALARM mode.
LT_L1_CHIP_BUSY	Chip is BUSY - typically chip is still booting.
LT_L1_INT_TIMEOUT	Interrupt pin did not fire as expected.
LT_L3_SLOT_NOT_EMPTY	L3 result [API R_Mem_Data_Write]: The target slot is already written.
LT_L3_SLOT_EXPIRED	L3 result [API R_Mem_Data_Write]: The target FLASH slot has expired.
LT_L3_INVALID_KEY	L3 result [API EDDSA_Sign, ECDSA_Sign, ECC_Key_Read]: The key in selected slot is invalid or corrupted.
LT_L3_UPDATE_ERR	L3 result [API MCounter_Update]: Update operation failed (i.e. mcounter done at 0).
LT_L3_COUNTER_INVALID	L3 result [API MCounter_Update, MCounter_Get]: The Monotonic Counter is disabled or locked.
LT_L3_SLOT_EMPTY	L3 result [API Pairing_Key_Read]: The requested slot is empty and contains no valid data.
LT_L3_SLOT_INVALID	L3 result [API Pairing_Key_Read]: The slot content is invalidated.
LT_L3_OK	L3 Command successfully executed.
LT_L3_FAIL	Error during processing of the L3 command.
LT_L3_UNAUTHORIZED	Insufficient User Access Privileges.
LT_L3_INVALID_CMD	Unknown L3 Command packet.
LT_L3_HARDWARE_FAIL	L3 result [API Pairing_Key_Write, Pairing_Key_Invalidate, R_Config_Write, I_Config_Write, R_Mem_Data_Write]: A hardware error occurred during a write operation.
LT_L3_DATA_LEN_ERROR	L3 data does not have an expected length.
LT_L3_RES_SIZE_ERROR	L3 response RES_SIZE have an invalid size. This can be caused by an attack or a bug.
LT_L3_BUFFER_TOO_SMALL	L3 buffer is too small to parse this L3 command. If this error is raised, either the buffer is too small to accept the result, or RES_SIZE field in the response is invalid (attack or a bug).
LT_L3_R_MEM_DATA_READ_SLOT_EMPTY	User slot is empty.
LT_L3_RESULT_UNKNOWN	Unknown L3 RESULT value.
LT_L2_REQ_CONT	There is more than one chunk to be expected for a current request.
LT_L2_RES_CONT	There is more than one chunk to be received for a current response.
LT_L2_RESP_DISABLED	The L2 Request frame is disabled and can’t be executed.
LT_L2_HSK_ERR	There were an error during handshake establishing.
LT_L2_NO_SESSION	There is no secure session.
LT_L2_TAG_ERR	There were error during checking message authenticity.
LT_L2_CRC_ERR	l2 request contained crc error
LT_L2_GEN_ERR	There were some other error.
LT_L2_NO_RESP	Chip has no response to be transmitted.
LT_L2_UNKNOWN_REQ	ID of last request is not known to TROPIC01.
LT_L2_IN_CRC_ERR	l2 response frame contains CRC error
LT_L2_RSP_LEN_ERROR	L2 data does not have an expected length (invalid value in RSP_LEN field)
LT_L2_STATUS_UNKNOWN	Unknown L2 STATUS value.
LT_CERT_STORE_INVALID	Certificate store likely does not contain valid data.
LT_CERT_UNSUPPORTED	Certificate store contains ASN1-DER syntax that is beyond the supported subset.
LT_CERT_ITEM_NOT_FOUND	Certificate does not contain requested item.
LT_NONCE_OVERFLOW	The nonce has reached its maximum value.
LT_RET_T_LAST_VALUE	Special helper value used to signalize the last enum value, used in lt_ret_verbose.
