 # Matter Shell Application

 A [chip-shell](../README.md) project on the Texas Instruments CC13XX_26XX family
 of Wireless MCUs.

 ## Building

 ### Preparation

 Some initial setup is necessary for preparing the build environment. This
 section will need to be done when migrating to new versions of the SDK. This
 guide assumes that the environment is linux based, and recommends Ubuntu 20.04.

 -   Download and install [SysConfig][sysconfig]. This can be done simply with
     the following commands.

     ```
     $ cd ~
     $ `wget https://dr-download.ti.com/software-development/ide-configuration-compiler-or-debugger/MD-nsUM6f7Vvb/1.15.0.2826/sysconfig-1.15.0_2826-setup.run`
     $ chmod +x sysconfig-1.15.0_2826-setup.run
     $ ./sysconfig-1.15.0_2826-setup.run
     ```

 -   Run the bootstrap script to setup the build environment.

     ```
     $ cd ~/connectedhomeip
     $ source ./scripts/bootstrap.sh

     ```

 ### Compilation

 It is necessary to activate the environment in every new shell. Then run GN and
 Ninja to build the executable.

 -   Activate the build environment with the repository activate script.

     ```
     $ cd ~/connectedhomeip
     $ source ./scripts/activate.sh

     ```

 -   Run the build to produce a default executable. By default on Linux both the
     TI SimpleLink SDK and Sysconfig are located in a `ti` folder in the user's
     home directory, and you must provide the absolute path to them. For example
     `/home/username/ti/sysconfig_1.15.0`. On Windows the default directory is
     `C:\ti`. Take note of this install path, as it will be used in the next
     step.

     ```
     $ cd ~/connectedhomeip/examples/shell/cc13x2x7_26x2x7
     OR
     $ cd ~/connectedhomeip/examples/shell/cc13x4_26x4
     $ gn gen out/debug --args="ti_sysconfig_root=\"$HOME/ti/sysconfig_1.15"
     $ ninja -C out/debug

     ```

     If you would like to define arguments on the command line you may add them
     to the GN call.

     ```
     gn gen out/debug --args="ti_sysconfig_root=\"$HOME/ti/sysconfig_1.15.0\" target_defines=[\"CC13X4_26X4_ATTESTATION_CREDENTIALS=1\"]"
     ```

 ## Programming

 Loading the built image onto a LaunchPad is supported through two methods;
 Uniflash and Code Composer Studio (CCS). UniFlash can be used to load the image.
 Code Composer Studio can be used to load the image and debug the source code.

 ### Code Composer Studio

 Programming with CCS will allow for a full debug environment within the IDE.
 This is accomplished by creating a target connection to the XDS110 debugger and
 starting a project-less debug session. The CCS IDE will attempt to find the
 source files on the local machine based on the debug information embedded within
 the ELF. CCS may prompt you to find the source code if the image was built on
 another machine or the source code is located in a different location than is
 recorded within the ELF.

 Download and install [Code Composer Studio][ccs].

 First open CCS and create a new workspace.

 Create a target connection (sometimes called the CCXML) for your target SoC and
 debugger as described in the [Manual Method][ccs_manual_method] section of the
 CCS User's Guide.

 Next initiate a project-less debug session as described in the [Manual
 Launch][ccs_manual_launch] section of the CCS User's Guide.

 CCS should switch to the debug view described in the [After
 Launch][ccs_after_launch] section of the User's Guide. The SoC core will likely
 be disconnected and symbols will not be loaded. Connect to the core as described
 in the [Debug View][ccs_debug_view] section of the User's Guide. Once the core
 is connected, use the `Load` button on the toolbar to load the ELF image.

 Note that the default configuration of the CCXML uses 2-wire cJTAG instead of
 the full 4-wire JTAG connection to match the default jumper configuration of the
 LaunchPad.

 ### UniFlash

 Uniflash is Texas Instrument's uniform programming tool for embedded processors.
 This will allow you to erase, flash, and inspect the SoC without setting up a
 debugging environment.

 Download and install [UniFlash][uniflash].

 First open UniFlash. Debug probes connected to the computer will usually be
 displayed under the Detected Devices due to the automatic device detection
 feature. If your device does not show up in this view it my be disconnected, or
 you may have to create a New Configuration. If you already have a CCXML for your
 SoC and debug connection you can use that in the section at the bottom. Once
 your device is selected, click the `Start` button within the section to launch
 the session.

 Select the ELF image to load on the device with the `Browse` button. This file
 is placed in the `out/debug` folder by this guide and ends with the `*.out` file
 extension. For OTA enabled applications, the standalone image will instead end
 with the `*-bim.hex` file extension. This this is a combined image with
 application and and `BIM` included.

 Finally click the `Load Image` button to load the executable image onto the
 device. You should be able to see the log output over the XDS110 User UART.

 Note that programming the device through JTAG sets the Halt-in-Boot flag and may
 cause issues when performing a software reset. This flag can be reset by
 power-cycling the LaunchPad.

 ## Running the Example

 By default the log output will be sent to the Application/User UART. Open a
 terminal emulator to that port to see the output with the following options:

 | Parameter    | Value    |
 | ------------ | -------- |
 | Speed (baud) | `115200` |
 | Data bits    | `8`      |
 | Stop bits    | `1`      |
 | Parity       | `None`   |
 | Flow control | `None`   |

 ## Running the Example

 Once a device has been flashed with this example, it can now join and operate in
 an existing Matter network. The following sections assume that a Matter network
 is already active, and has at least one [OpenThread Border
 Router][ot_border_router_setup].

 For insight into what other components are needed to run this example, please
 refer to our [Matter Getting Started Guide][matter-e2e-faq].

 For help with the shell itself, refer to the
 [shell example README](../README.md).
