Edge Impulse Firmware for TI LAUNCHXL-CC1352P

Edge Impulse enables developers to create the next generation of intelligent device solutions with embedded machine learning. This repository contains the Edge Impulse firmware for TI LAUNCHXL-CC1352P development board. This device supports all of Edge Impulse's device features, including ingestion, remote management and inferencing.

Note: Do you just want to use this development board to collect data with Edge Impulse? No need to build this firmware. View the getting started guide for a pre-built firmware image and flashing instructions. Or, you can use the data forwarder to capture data from any sensor.

Requirements

Hardware

• TI LAUNCHXL-CC1352P.
• BOOSTXL-SENSORS - contains additional sensors and allows to connect (more) external sensors.
• CC3200AUDBOOST - adds audio to your project.

Hardware Setup

The add-on boards can be stacked on each other with the CC3200AUDBOOST stacked on the BOOSTXL-SENSOR add-on. However hardware modifications are required to get the CC3200AUDBOOST to work for CC1352P.

See Hardware Setup > Codec Setup - CC3200AUDBOOST in Quick Start Guide and follow steps for CC13x2.

Software

• Edge Impulse CLI.
• Install the following tools separately or install TI CCSTUDIO which comes bundled with:
  • XDCTools
  • SYSCONFIG
  • ARM GCC Toolchain 7
• Install UniFlash.
• Download TI Simplelink SDK.
• Download FreeRTOS 202107.00.

Texas Instruments Simplelink SDK

• Uses the TI Simplelink SDK simplelink_cc13x2_26x2_sdk_5.20.00.52.
• Set SIMPLELINK_CC13X2_26X2_SDK_INSTALL_DIR in gcc/makefile to the path to TI SimpleLink SDK, referred to as <TI SDK FOLDER>.
• Set the following variables in <TI SDK FOLDER>/imports.mak:
  • SYSCONFIG_TOOL e.g. /home/user/ti/sysconfig_1.8.2/sysconfig_cli.sh
  • GCC_ARMCOMPILER e.g. /home/user/ti/ccs1040/ccs/tools/compiler/gcc-arm-none-eabi-7-2017-q4-major:
  • FREERTOS_INSTALL_DIR e.g. /home/user/FreeRTOS/

Building the application

The FreeRTOS kernel must be built before the applicaiton can be built. To do so,

• Replace the FreeRTOSConfig.h in <TI SDK FOLDER>/kernel/freertos/builds/cc13x2_cc26x2/release with gcc/FreeRTOSConfig.h and then in a terminal:

   $ cd <TI SDK FOLDER>/kernel/freertos
   $ make

Or do all steps by:

   $ cd gcc
   $ make build-kernel

1. Build the application by calling make as follows:

   $ cd gcc
   $ make
   

2. Connect the board to your computer using USB.

3. Flash the board

   Windows

   $ dslite.bat -c tools\user_files\configs\cc1352p1f3.ccxml -l tools\user_files\settings\generated.ufsettings -e -f -v gcc\build\firmware-ti-launchxl.out
   

   Linux, macOS

   $ export PATH=/home/user/ti/:${PATH}
   $ dslite.sh -c tools/user_files/configs/cc1352p1f3.ccxml -l tools/user_files/settings/generated.ufsettings -e -f -v gcc/build/firmware-ti-launchxl.out
   

   Note: the above expects UniFlash is installed and dslite.sh/dslite.bat to be in the system path.

Or build with Docker

1. Build the Docker image:

   $ docker build -t ti-build .
   

2. Build the application by running the container as follows:

   Windows

   $ docker run --rm -it -v "%cd%":/app ti-build /bin/bash -c "cd gcc && make build-kernel && make"
   

   Linux, macOS

   $ docker run --rm -it -v $PWD:/app:delegated ti-build /bin/bash -c "cd gcc && make build-kernel && make"
   

3. Connect the board to your computer using USB.

4. Flash the board:

   $ dslite.sh -c tools/user_files/configs/cc1352p1f3.ccxml -l tools/user_files/settings/generated.ufsettings -e -f -v gcc/build/firmware-ti-launchxl.out
   

Troubleshooting

Flashing

If during flashing you encounter flashing issue.

Then ensure:

1. your device is properly connected and/or your cable is not damaged.
2. you have the proper permissions to access the USB device.

If on Linux you may want to try copying tools/71-ti-permissions.rules to /etc/udev/rules.d/. Then re-attach the USB cable and try again.

Out of (RAM) Memory: (-1002)

TI LAUNCHXL-CC1352P has 80kB of RAM which may not always be enough to run your model. If this is the case try reducing the RAM usage of your model.
