Multipage Blob Support
----------------------
By default, binary blobs are allowed to span over multiple pages and written in the format mentioned in section :ref:`structure_of_entry`.
By default, binary blobs are allowed to span over multiple pages and written in the format mentioned in section :ref:`structure_of_entry`.
If older format is intended to be used, the utility provides an option to disable this feature.
Encryption Support

Running the utility
-------------------
*Usage*::
**Usage**::
python nvs_partition_gen.py [--version {v1,v2}] input output
You can run this utility in two modes:
- Normal mode - Binary generated in this mode is an unencrypted binary file.
- Encryption mode - Binary generated in this mode is an encrypted binary file.
*In normal mode:*
A sample CSV file is provided with the utility. You can run the utility using below command::
python nvs_partition_generator.py sample.csv sample.bin
*In encryption mode:*
You can run the utility using below commands:
- By taking encryption keys as an input file. A sample encryption keys file is provided with the utility::
python nvs_partition_gen.py sample.csv sample_encrypted.bin --encrypt True --keyfile testdata/keys.txt
- By enabling generation of encryption keys::
python nvs_partition_gen.py sample.csv sample_encrypted.bin --encrypt True --keygen True
.. note:: In encryption mode, this utility creates a binary file named `encryption_keys.bin` containing the encryption keys used. This binary file is compatible with NVS key-partition structure. Refer to :ref:`nvs_key_partition` for more details.
You can also provide the format version number while running this utility:
- Multipage Blob Support Enabled (v2)
- Multipage Blob Support Disabled (v1)
*Multipage Blob Support Enabled (v2):*
You can run the utility in this format by setting the version parameter to v2, as shown below.
A sample CSV file is provided with the utility::
python nvs_partition_gen.py sample_multipage_blob.csv partition_multipage_blob.bin --version v2
*Multipage Blob Support Disabled (v1):*
You can run the utility in this format by setting the version parameter to v1, as shown below.
A sample CSV file is provided with the utility::
python nvs_partition_gen.py sample_singlepage_blob.csv partition_single_page.bin --version v1
python nvs_partition_gen.py [-h] [--input INPUT] [--output OUTPUT]
[--size SIZE] [--version {v1,v2}]
[--keygen {true,false}] [--encrypt {true,false}]
[--keyfile KEYFILE]
+------------------------+----------------------------------------------------------------------------------------------+
| Arguments | Description |
+========================+==============================================================================================+
| input | Path to CSV file to parse. Will use stdin if omitted |
| --input INPUT | Path to CSV file to parse. |
+------------------------+----------------------------------------------------------------------------------------------+
| output | Path to output converted binary file. Will use stdout if omitted |
| --output OUTPUT | Path to output generated binary file. |
+------------------------+----------------------------------------------------------------------------------------------+
| size | Size of NVS Partition in bytes (must be multiple of 4096) |
| --size SIZE | Size of NVS Partition in bytes (must be multiple of 4096) |
+------------------------+----------------------------------------------------------------------------------------------+
| --version {v1,v2} | Set version. Default: v2 |
+-------------------------------+---------------------------------------------------------------------------------------+
| --keygen {True,False} | Generate keys for encryption. Default: False |
| | (Applicable only if encryption mode is true) |
| --version {v1,v2} | Set version. Default: v2 |
+------------------------+----------------------------------------------------------------------------------------------+
| --encrypt {True,False} | Set encryption mode. Default: False |
| --keygen {true,false} | Generate keys for encryption. Creates an `encryption_keys.bin` file (in current directory). |
| | Default: false |
+------------------------+----------------------------------------------------------------------------------------------+
| --encrypt {true,false} | Set encryption mode. Default: false |

You can run this utility in two modes:
- Normal mode - Binary generated in this mode is an unencrypted binary file.
- Encryption mode - Binary generated in this mode is an encrypted binary file.
**In normal mode:**
*Usage*::
python nvs_partition_gen.py [-h] --input INPUT --output OUTPUT
--size SIZE [--version {v1,v2}]
[--keygen {true,false}] [--encrypt {true,false}]
[--keyfile KEYFILE]
You can run the utility using below command::
python nvs_partition_gen.py --input sample.csv --output sample.bin --size 0x3000
**In encryption mode:**
*Usage*::
python nvs_partition_gen.py [-h] --input INPUT --output OUTPUT
--size SIZE --encrypt {true,false}
--keygen {true,false} | --keyfile KEYFILE
[--version {v1,v2}]
You can run the utility using below commands:
- By taking encryption keys as an input file. A sample encryption keys binary file is provided with the utility::
python nvs_partition_gen.py --input sample.csv --output sample_encrypted.bin --size 0x3000 --encrypt true --keyfile testdata/sample_encryption_keys.bin
- By enabling generation of encryption keys::
python nvs_partition_gen.py --input sample.csv --output sample_encrypted.bin --size 0x3000 --encrypt true --keygen true
*To generate* **only** *encryption keys with this utility* ( Creates an `encryption_keys.bin` file in current directory ): ::
python nvs_partition_gen.py --keygen true
.. note:: This `encryption_keys.bin` file is compatible with NVS key-partition structure. Refer to :ref:`nvs_key_partition` for more details.
You can also provide the format version number (in any of the two modes):
- Multipage Blob Support Enabled (v2)
- Multipage Blob Support Disabled (v1)
**Multipage Blob Support Enabled (v2):**
You can run the utility in this format by setting the version parameter to v2, as shown below.
A sample CSV file is provided with the utility::
python nvs_partition_gen.py --input sample_multipage_blob.csv --output partition_multipage_blob.bin --size 0x3000 --version v2
**Multipage Blob Support Disabled (v1):**
You can run the utility in this format by setting the version parameter to v1, as shown below.
A sample CSV file is provided with the utility::
python nvs_partition_gen.py --input sample_singlepage_blob.csv --output partition_single_page.bin --size 0x3000 --version v1
.. note:: *When flashing the binary onto the device, make sure it is consistent with the application's sdkconfig.*
Caveats
-------
- Utility doesn't check for duplicate keys and will write data pertaining to both keys. User needs to make sure keys are distinct.
