There are two types of CC3100 and CC3200 devices: production devices (PG1.33) and pre-production devices (ES1.32 or lower). Both devices are not considered secured devices.
Uniflash version v3.2.0.00123 or earlier had the option to format the device as secured (in case it is not) and also create secured files. However, secured file system support is deprecated from other Uniflash v3 versions since this feature is not supported on CC3100/CC3200.
Support for the secured file system was added for the next generation of SimpleLink Wi-Fi devices. For more information, go to ti.com/simplelinkwifi.
