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.

• Device activation is not supported at the moment. If you are interested in activation implemented by SEGGER, please get in touch with us directly: https://www.segger.com/support/technical-support/.

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.

1. TI Simplelink Wi-Fi Toolbox.
2. TI Simplelink Wi-Fi SDK.
3. TI SYSCONFIG Utility or TI Code Composer Studio with built-in SYSCONFIG Utility.

Usage

DevPro -operation [operation_name] -if SWD -speed 4000 [-SetConfigVal parameter_name=value] -ScriptFile PCode_DevPro_TI_CC35xx.pex
