What the SDK provides in each feature area, the CONFIG_* keys that turn it on, and a hands-on walk-through on the IPRO7AI Reef EVK. New to the SDK? Build your own application first in Create Your First Application.

  • Architecture

    Layers, the FreeRTOS and Zephyr paths, components, directory layout and BSP, traced through the out-of-box firmware.

  • Build System & Configuration

    Build flow, .config and autoconf.h, the Reef configurations, memory layout, new applications.

    The Reef OV5640 camera: DVP, ISP, hardware MJPEG, the USB webcam, RTSP and software JPEG decoding.

  • AI & NPU

    Prebuilt inference runtime, model storage and loading, the Reef AI applications.

  • IPRO AI Teach

    Image, voiceprint and sensor recognition in one Reef firmware: collect, train and deploy from IPRO AI Studio.

  • Networking

    lwIP and mbedTLS; Wi-Fi on the Reef through the IPRO6S FIN card over SDIO; RMII Ethernet.

  • Zephyr RTOS
