Chapter 2. API Reference
ESP_ERR_NOT_FINISHED (0x10c): There are items remained to retrieve
ESP_ERR_NVS_BASE (0x1100): Starting number of error codes
ESP_ERR_NVS_NOT_INITIALIZED (0x1101): The storage driver is not initialized
ESP_ERR_NVS_NOT_FOUND (0x1102): Id namespace doesn’t exist yet and mode is NVS_READONLY
ESP_ERR_NVS_TYPE_MISMATCH (0x1103): The type of set or get operation doesn’t match the type of value
stored in NVS
ESP_ERR_NVS_READ_ONLY (0x1104): Storage handle was opened as read only
ESP_ERR_NVS_NOT_ENOUGH_SPACE (0x1105): There is not enough space in the underlying storage to save the
value
ESP_ERR_NVS_INVALID_NAME (0x1106): Namespace name doesn’t satisfy constraints
ESP_ERR_NVS_INVALID_HANDLE (0x1107): Handle has been closed or is NULL
ESP_ERR_NVS_REMOVE_FAILED (0x1108): The value wasn’t updated because flash write operation has failed.
The value was written however, and update will be finished after re-initialization of nvs, provided that flash operation
doesn’t fail again.
ESP_ERR_NVS_KEY_TOO_LONG (0x1109): Key name is too long
ESP_ERR_NVS_PAGE_FULL (0x110a): Internal error; never returned by nvs API functions
ESP_ERR_NVS_INVALID_STATE (0x110b): NVS is in an inconsistent state due to a previous error. Call
nvs_flash_init and nvs_open again, then retry.
ESP_ERR_NVS_INVALID_LENGTH (0x110c): String or blob length is not sufficient to store data
ESP_ERR_NVS_NO_FREE_PAGES (0x110d): NVS partition doesn’t contain any empty pages. This may happen
if NVS partition was truncated. Erase the whole partition and call nvs_flash_init again.
ESP_ERR_NVS_VALUE_TOO_LONG (0x110e): String or blob length is longer than supported by the implemen-
tation
ESP_ERR_NVS_PART_NOT_FOUND (0x110f): Partition with specified name is not found in the partition table
ESP_ERR_NVS_NEW_VERSION_FOUND (0x1110): NVS partition contains data in new format and cannot be
recognized by this version of code
ESP_ERR_NVS_XTS_ENCR_FAILED (0x1111): XTS encryption failed while writing NVS entry
ESP_ERR_NVS_XTS_DECR_FAILED (0x1112): XTS decryption failed while reading NVS entry
ESP_ERR_NVS_XTS_CFG_FAILED (0x1113): XTS configuration setting failed
ESP_ERR_NVS_XTS_CFG_NOT_FOUND (0x1114): XTS configuration not found
ESP_ERR_NVS_ENCR_NOT_SUPPORTED (0x1115): NVS encryption is not supported in this version
ESP_ERR_NVS_KEYS_NOT_INITIALIZED (0x1116): NVS key partition is uninitialized
ESP_ERR_NVS_CORRUPT_KEY_PART (0x1117): NVS key partition is corrupt
ESP_ERR_NVS_CONTENT_DIFFERS (0x1118): Internal error; never returned by nvs API functions. NVS key is
different in comparison
ESP_ERR_NVS_WRONG_ENCRYPTION (0x1119): NVS partition is marked as encrypted with generic flash en-
cryption. This is forbidden since the NVS encryption works differently.
ESP_ERR_ULP_BASE (0x1200): Offset for ULP-related error codes
ESP_ERR_ULP_SIZE_TOO_BIG (0x1201): Program doesn’t fit into RTC memory reserved for the ULP
ESP_ERR_ULP_INVALID_LOAD_ADDR (0x1202): Load address is outside of RTC memory reserved for the
ULP
ESP_ERR_ULP_DUPLICATE_LABEL (0x1203): More than one label with the same number was defined
ESP_ERR_ULP_UNDEFINED_LABEL (0x1204): Branch instructions references an undefined label
