Deploying the Firmware with Native Windows

This document explains how to deploy the software using CMake and Ninja. If you are not using native Windows MSVC build tools and instead using a Linux emulation tool such as WSL, refer to Deploying the Firmware with Linux or macOS.

To install Ninja follow install instructions at https://ninja-build.org/ or on Windows install with winget by running the following commands in PowerShell:

# Install
winget install Ninja-build.ninja
# Reload user Path
$env:Path=[System.Environment]::GetEnvironmentVariable("Path","User")

Building the Host Applications

This application requires a host application to create the flash data partition. Run the following commands in the root folder to build the host application using your native Toolchain:

Note

Permissions may be required to install the host applications.

Note

A C/C++ compiler, such as Visual Studio or MinGW, must be included in the path.

Before building the host application, you will need to add the path to the XTC Tools to your environment.

set "XMOS_TOOL_PATH=<path-to-xtc-tools>"

Then build the host application:

cmake -G Ninja -B build_host
cd build_host
ninja install

The host applications will be installed at %USERPROFILE%\.xmos\bin, and may be moved if desired. You may wish to add this directory to your PATH variable.

Building the Firmware

Run the following commands in the root folder to build the firmware:

cmake -G Ninja -B build --toolchain=xmos_cmake_toolchain/xs3a.cmake
cd build
ninja example_ffd_<speech_engine>

Running the Firmware

Before running the firmware, the filesystem and model must be flashed to the data partition.

Within the root of the build folder, run:

ninja flash_app_example_ffd_<speech_engine>

After this command completes, the application will be running.

After flashing the data partition, the application can be run without reflashing. If changes are made to the data partition components, the application must be reflashed.

From the build folder run:

xrun --xscope example_ffd_<speech_engine>.xe

Debugging the Firmware

To debug with xgdb, from the build folder run:

xgdb -ex "connect --xscope" -ex "run" example_ffd_<speech_engine>.xe
