Introduction

This builds a test binary which contains the NLUnitTests and can be flashed onto a device. The device is controlled using the included RPCs, through the python test runner.

Building

• Download the Simplicity Commander command line tool, and ensure that commander is your shell search path. (For Mac OS X, commander is located inside Commander.app/Contents/MacOS/.)

• Download and install a suitable ARM gcc tool chain: GNU Arm Embedded Toolchain 9-2019-q4-major

• Install some additional tools(likely already present for CHIP developers):

#Linux sudo apt-get install git libwebkitgtk-1.0-0 ninja-build

#Mac OS X brew install ninja

• Supported hardware:

  MG12 boards:

  • BRD4161A / SLWSTK6000B / Wireless Starter Kit / 2.4GHz@19dBm
  • BRD4164A / SLWSTK6000B / Wireless Starter Kit / 2.4GHz@19dBm
  • BRD4166A / SLTB004A / Thunderboard Sense 2 / 2.4GHz@10dBm
  • BRD4170A / SLWSTK6000B / Multiband Wireless Starter Kit / 2.4GHz@19dBm, 915MHz@19dBm
  • BRD4304A / SLWSTK6000B / MGM12P Module / 2.4GHz@19dBm

  MG21 boards: Currently not supported due to RAM limitation.

  • BRD4180A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@20dBm

  MG24 boards :

  • BRD4186A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@10dBm
  • BRD4187A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@20dBm

OR use GN/Ninja directly

      ```
      cd ~/connectedhomeip/src/test_driver/efr32/
      git submodule update --init
      source third_party/connectedhomeip/scripts/activate.sh
      export EFR32_BOARD=BRD4161A
      gn gen out/debug
      ninja -C out/debug
      ```

• To delete generated executable, libraries and object files use:

    ```
    cd ~/connectedhomeip/src/test_driver/efr32/
    rm -rf out/
    ```
  

Running The Tests

Build the runner using gn:

```
cd <connectedhomeip>/src/test_driver/efr32
gn gen out/debug
ninja -C out/debug runner
```

Or build using build script from the root

```
cd <connectedhomeip>
./scripts/build/build_examples.py --target-glob '*nl-test-runner' build
```

The runner will be installed into the venv and python wheels will be packaged in the output folder for deploying.

• To run the tests:

  python -m nl_test_runner.nl_test_runner -d /dev/ttyACM1 -f out/debug/chip-efr32-device_tests.s37 -o out.log
