Bouffalo Lab BL618 G0 evaluation board

Overview

The Bouffalo Lab BL618 G0 is an evaluation board based on the Bouffalo Lab BL618 SoC. The BL618 is a Wi-Fi 6 + BLE 5.3 + IEEE 802.15.4 (Zigbee/Thread) capable RISC-V microcontroller with a maximum clock frequency of 320 MHz and 480 KB of SRAM.

The board features:

  • BL618M05Q2I Soc with BL618 core

  • W25Q64 8 MB external SPI flash

  • 32 MB embedded PSRAM

  • On-board CK-Link debugger (no external probe needed)

  • USB 2.0 HS OTG via USB-C

  • MicroSD (TF) card slot

  • IPEX antenna connector

  • Expansion headers with all unused GPIOs broken out

  • Support for optional expansion modules: I2S audio, SPI display, DVP camera

  • One user LED (GPIO32)

  • One user button (GPIO33)

  • Reset and Boot buttons

System Clock

The BL618 G0 evaluation board is configured to run at maximum speed (320MHz).

Serial Port

The bl618g0 board uses UART0 as default serial port. It is connected to the on-board CK-Link USB-to-UART interface and used for both flashing and console output.

Programming and Debugging

The bl618g0 board supports the runners and associated west commands listed below.

flash debug

Samples

  1. Build the Zephyr kernel and the Hello World sample application:

    # From the root of the zephyr repository
west build -b bl618g0 samples/hello_world
west flash

  2. Run your favorite terminal program to listen for output:

    $ screen /dev/ttyACM0 115200

    Connection should be configured as follows:

    • Speed: 115200

    • Data: 8 bits

    • Parity: None

    • Stop bits: 1

    Then, press and release RST button

    *** Booting Zephyr OS build v4.4.0 ***
Hello World! bl618g0/bl618m05q2i

Congratulations, you have bl618g0 configured and running Zephyr.
