Astra MCU SDK Documentation

The Astra MCU SDK is the unified development platform for Synaptics MCUs, purpose-built for edge AI, vision, and audio applications. It standardizes workflows across devices and kits with both VS Code and command-line paths for setup, build, flash, and debug.

It combines optimized libraries, a production-grade build system, and integrated tooling so teams can move from evaluation to production quickly:

• Optimized AI stack with TensorFlow Lite Micro and CMSIS-NN accelerations.

• Kconfig + CMake + Ninja build system with reproducible defconfigs and fast incremental builds.

• Cross-platform toolchain support for GCC, Arm Compiler 6, and LLVM Clang on Windows, Linux, and macOS.

• Rich examples and out-of-tree workflows to keep applications cleanly separated from the SDK.

• Integrated tooling for image conversion, flashing, logging, and memory analysis.

• Optional VS Code development environment.

Getting Started

Step 1: Obtain the SDK

Extract or clone the SDK to a local directory (for example, /path/to/Astra_MCU_SDK). This folder is your SDK root, in the rest of this document it will be refered to as .

• On Windows keep the path short (less than 100 characters) to avoid path length issues.

• Note: In order to clone the Astra MCU SDK repository you must first install Git LFS. For more details, see https://git-lfs.com/.
