TI CC35xx Device Provisioning
The CC35xx series of devices comes with enhanced security features. SEGGER implemented support for these features via a dedicated utility called Device Provisioner. For more information about this, please refer to the Device Provisioner article. CC35xx Security features are implemented in the PCode_DevPro_TI_CC35xx.pex script file.
Important information
TI CC35xx series of devices uses a dedicated Cortex-M3 core for device activation, managing debug access to main Cortex-M33 core, programming flash memory, etc. Every action will require an appropriate service firmware for Cortex-M3 core, e.g. ti_debug.CC35XXE.sign.bin inside Simplelink Wi-Fi Toolbox is used for opening debug access. After application is created it must be signed using Simplelink Wi-Fi Toolbox post-build script. It will generate a signed application binary for programming using a debug_action_request.sign.bin file, which is used to open debug access for J-Link/Flasher.
Prerequisites
The following tools and software development kits must be installed in order to get access to signed Cortex-M3 firmwares and to sign a built application.
- TI Simplelink Wi-Fi Toolbox.
- TI Simplelink Wi-Fi SDK.
- TI SYSCONFIG Utility or TI Code Composer Studio with built-in SYSCONFIG Utility.
