Introduction
|
||||
------------
|
||||
|
||||
The utility :component_file:`nvs_flash/nvs_partition_generator/nvs_partition_gen.py` creates a binary file, compatible with the NVS architecture defined in :doc:`Non-Volatile Storage </api-reference/storage/nvs_flash>`, based on the key-value pairs provided in a CSV file.

|
||||
|
||||
This utility is ideally suited for generating a binary blob, containing data specific to ODM/OEM, which can be flashed externally at the time of device manufacturing. This allows manufacturers to generate many instances of the same application firmware with customized parameters for each device, such as a serial number.

Encryption-Decryption Support

-----------------------------
|

The NVS Partition Generator utility also allows you to create an encrypted binary file and decrypt an encrypted one. The utility uses the XTS-AES encryption. Please refer to :doc:`NVS Encryption <nvs_encryption>` for more details.

在加密模式下使用该程序,需安装下列软件包:
|
