Overview

The Synaptics Astra™ SR100 Series of AI MCUs is designed to deliver high-performance, AI-Native, multimodal compute to consumer, enterprise, and industrial Internet of Things (IoT) workloads.

  • The Astra Machina Micro SR100 Evaluation Platform Kit features the following key components:

    • Synaptics SR110 (122-FCCSP) Audio & Vision AI processor
    • Debug IC Synaptics SR100 (84-WCCSP)
    • Storage: 128 Mbit QSPI NOR Flash
    • PMIC: Buck-Boost DC/DC for SR100 VBAT
    • Highly sensitive ambient light sensor: TCS34303
    • 3-axis accelerometer: MC3479
    • M.2 E-key 2230 receptacle: Supports SDIO, UART, and PCM for Wi-Fi/BT modules
    • 2x USB 2.0 Type-C™ ports: Peripheral mode (Hi-Speed) and system power input
    • Push buttons for system reset and wake-up
    • Slide switches for image programming, mute control, and debugging
    • Several LEDs, including two user-controllable LEDs

  • Daughter card interface options:

    • 2x MIPI CSI-2® 2-lane RX interfaces (1.5 Gb/s max bandwidth): CSI0 on Samtec™ connector (shared with DVP), CSI1 on 15-pin FPC connector
    • 1x MIPI CSI-2® TX interface (1.5 Gb/s max bandwidth) on 15-pin FPC connector
    • SWD JTAG daughter card for debugging
    • 2x 20-pin headers with GPIOs are for additional application
    • 4-pin header for UART debugging
    • 3-pin header for PIR

  • System power supply:

    • USB Type-C
    • 2-pin, 2.0 mm pitch header for 1-cell Li-ion battery
    • 3-pin header for system power source selection

Building

To build an application, use the standard Zephyr command. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sr100_rdk :goals: build

Flashing

Connect the board using the USB-C connector to your host machine. Make sure you can see the CMSIS-DAP endpoint using lsusb:

.. code-block:: console

$ lsusb | grep CMSIS-DAP Bus 001 Device 058: ID cafe:4006 Synaptics, Inc SR100 CMSIS-DAP

Next, run the west debugserver command.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sr100_rdk :goals: debugserver

Now, in a separate terminal, run the flashing script provided by Synaptics:

.. code-block:: console

python openocd_flash.py build/zephyr/zephyr.bin 0x0 0x0 1
