LAUNCHCC3220MODASF: SLImageCreator and Restore To Factory Configuration

Part Number: LAUNCHCC3220MODASF

Tool/software:

Hello all,

I use UniFlash 9.1 and want to create a UniFlash Image for the CC3220MODASF MCU using the command line tool SLImageCreator.
In the resulting UniFlash-Image all Reset-To-Factory specific features must be disabled.

SinceI could not find any documentation about the JSON configuration file mentioned in the TI documentation SWRU469H, I created an empty UniFLash Project myProject with the desired settings and exported it as the usual ZIP-File.

I extracted the file myproject.json from the ZIP file.
This file contains two JSON keys that contain the string "Factory"

"EnableReturnToFactory":"none", 
"ReturnToFactoryGPIO":"1", 

Next steps using the SLImageCreator command line interface:
* creation of a new UniFlash project myproject based on that mentioned extracted JSON file
* add some certificate files
* add and signs mcu file
* add service pack
* set the TI Dummy certstore

SLImageCreator project new --project_path %cd%\temp\projects --name myproject --device CC3220SF --cfg_json myproject.json --overwrite

SLImageCreator project add_file --project_path %cd%\temp\projects --name myproject --file %cd%\vendor\cert_rootca --fs_path "cert_rootca" --overwrite

SLImageCreator project add_file --project_path %cd%\temp\projects --name myproject --file %cd%\vendor\cert_codesign --fs_path "cert_codesign" --overwrite

SLImageCreator project add_file --project_path %cd%\temp\projects --name myproject --file %cd%\mybin.bin --mcu --priv %cd%\vendor\cert_rootca_key.pem --cert cert_rootca --overwrite

SLImageCreator project set_certstore --project_path %cd%\temp\projects --name myproject --file %cd%\vendor\my_catalogue.lst --sign %cd%\vendor\my_catalogue.lst.signed.bin

SLImageCreator.exe project set_sp   --project_path %cd%\temp\projects --name myproject --file %cd%\sp_3.21.0.1_2.7.0.0_2.2.0.7.bin

SLImageCreator project export --project_path %cd%\temp\projects --name myproject  --file %cd%\myproject.zip


The process ends without errors.

The resulting project is as expected, with the exception that the entries relating to Restore-to-Factory have been overwritten and this functionality has been reactivated.
The JSON configuration files is overwritten by the first command.

SLImageCreator project new --project_path %cd%\temp\projects --name myproject --mode production --device CC3220SF --cfg_json myproject.json --overwrite


How can I create a UniFlash Project with the Reset-To-Factory settings disabled using the SLImageCreator.exe in combination with the JSON file?
Is there any documentation about the keys and values used in the JSON configuration file?

Many thanks,
Roman
