You can run the utility to generate factory images for each device using the command below. A sample CSV file is
provided with the utility:
python mfg_gen.py generate samples/sample_config.csv samples/sample_values_
singlepage_blob.csv Sample
→
The master value CSV file should have the path in the file type relative to the directory from which you are running
the utility.
To generate encrypted factory images for each device:
You can run the utility to encrypt factory images for each device using the command below. A sample CSV file is
provided with the utility:
• Encrypt by allowing the utility to generate encryption keys:
python mfg_gen.py generate samples/sample_config.csv samples/sample_values_
singlepage_blob.csv Sample
→
Note: Encryption key of the following format <outdir>/keys/keys-<prefix>-<fileid>.bin is cre-
ated.
Note: This newly created file having encryption keys in keys/ directory is compatible with NVS key-partition
structure. Refer to NVS key partition
• Encrypt by providing the encryption keys as input binary file:
python mfg_gen.py generate samples/sample_config.csv samples/sample_values_
singlepage_blob.csv Sample
→
To generate only encryption keys: Usage:
python mfg_gen.py generate-key [-h] [--keyfile KEYFILE] [--outdir OUTDIR]
