When the DFU controller sends requests to the DFU bootloader on the DFU target, the DFU bootloader answers with any of these result codes.
DFU request extended result codes.
When an event returns NRF_DFU_RES_CODE_EXT_ERROR, it also stores an extended error code. The transport layer can then send the extended error code together with the error code to give the controller additional information about the cause of the error.
| Enumerator | |
|---|---|
| NRF_DFU_EXT_ERROR_NO_ERROR |
No extended error code has been set. This error indicates an implementation problem. |
| NRF_DFU_EXT_ERROR_INVALID_ERROR_CODE |
Invalid error code. This error code should never be used outside of development. |
| NRF_DFU_EXT_ERROR_WRONG_COMMAND_FORMAT |
The format of the command was incorrect. This error code is not used in the current implementation, because NRF_DFU_RES_CODE_OP_CODE_NOT_SUPPORTED and NRF_DFU_RES_CODE_INVALID_PARAMETER cover all possible format errors. |
| NRF_DFU_EXT_ERROR_UNKNOWN_COMMAND |
The command was successfully parsed, but it is not supported or unknown. |
| NRF_DFU_EXT_ERROR_INIT_COMMAND_INVALID |
The init command is invalid. The init packet either has an invalid update type or it is missing required fields for the update type (for example, the init packet for a SoftDevice update is missing the SoftDevice size field). |
| NRF_DFU_EXT_ERROR_FW_VERSION_FAILURE |
The firmware version is too low. For an application, the version must be greater than the current application. For a bootloader, it must be greater than or equal to the current version. This requirement prevents downgrade attacks. |
| NRF_DFU_EXT_ERROR_HW_VERSION_FAILURE |
The hardware version of the device does not match the required hardware version for the update. |
| NRF_DFU_EXT_ERROR_SD_VERSION_FAILURE |
The array of supported SoftDevices for the update does not contain the FWID of the current SoftDevice. |
| NRF_DFU_EXT_ERROR_SIGNATURE_MISSING |
The init packet does not contain a signature. This error code is not used in the current implementation, because init packets without a signature are regarded as invalid. |
| NRF_DFU_EXT_ERROR_WRONG_HASH_TYPE |
The hash type that is specified by the init packet is not supported by the DFU bootloader. |
| NRF_DFU_EXT_ERROR_HASH_FAILED |
The hash of the firmware image cannot be calculated. |
| NRF_DFU_EXT_ERROR_WRONG_SIGNATURE_TYPE |
The type of the signature is unknown or not supported by the DFU bootloader. |
| NRF_DFU_EXT_ERROR_VERIFICATION_FAILED |
The hash of the received firmware image does not match the hash in the init packet. |
| NRF_DFU_EXT_ERROR_INSUFFICIENT_SPACE |
The available space on the device is insufficient to hold the firmware. |
| enum nrf_dfu_res_code_t |
DFU request result codes.
The DFU transport layer creates request events of type nrf_dfu_req_op_t. Such events return one of these result codes.
| Enumerator | |
|---|---|
| NRF_DFU_RES_CODE_INVALID |
Invalid opcode. |
| NRF_DFU_RES_CODE_SUCCESS |
Operation successful. |
| NRF_DFU_RES_CODE_OP_CODE_NOT_SUPPORTED |
Opcode not supported. |
| NRF_DFU_RES_CODE_INVALID_PARAMETER |
Missing or invalid parameter value. |
| NRF_DFU_RES_CODE_INSUFFICIENT_RESOURCES |
Not enough memory for the data object. |
| NRF_DFU_RES_CODE_INVALID_OBJECT |
Data object does not match the firmware and hardware requirements, the signature is wrong, or parsing the command failed. |
| NRF_DFU_RES_CODE_UNSUPPORTED_TYPE |
Not a valid object type for a Create request. |
| NRF_DFU_RES_CODE_OPERATION_NOT_PERMITTED |
The state of the DFU process does not allow this operation. |
| NRF_DFU_RES_CODE_OPERATION_FAILED |
Operation failed. |
| NRF_DFU_RES_CODE_EXT_ERROR |
Extended error. The next byte of the response contains the error code of the extended error (see nrf_dfu_ext_error_code_t). |
| nrf_dfu_ext_error_code_t ext_error_get | ( | void | ) |
Function for getting the most recent extended error code.
This function is used by the transport layer to fetch the most recent extended error code.
| nrf_dfu_res_code_t ext_error_set | ( | nrf_dfu_ext_error_code_t | error_code | ) |
Function for setting an extended error code that can be retrieved later.
When an extended error occurs in the DFU process, this function can be used to store the error.
| error_code | The error code to store. |
| NRF_DFU_RES_CODE_EXT_ERROR |
