Overview

BL602/BL604 is a Wi-Fi+BLE chipset introduced by Bouffalo Lab, which is used for low power consumption and high performance application development. The wireless subsystem includes 2.4G radio, Wi-Fi 802.11b/g/n and BLE 5.0 baseband/MAC design. The microcontroller subsystem includes a 32-bit RISC CPU with low power consumption, cache and memory. The power management unit controls the low power consumption mode. In addition, it also supports various security features. The external interfaces include SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR and GPIO.

The BL602 Development Board features a SiFive E24 32 bit RISC-V CPU with FPU, it supports High Frequency clock up to 192Mhz, have 128k ROM, 276kB RAM, 2.4 GHz WIFI 1T1R mode, support 20 MHz, data rate up to 72.2 Mbps, BLE 5.0 with 2MB phy. It is a secure MCU which supports Secure boot, ECC-256 signed image, QSPI/SPI Flash On-The-Fly AES Decryption and PKA (Public Key Accelerator).

Samples

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

# From the root of the zephyr repository
west build -b bl604e_iot_dvk samples/hello_world
west flash

1. Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyACM0. For example:

   $ minicom -D /dev/ttyACM0 -o
   

   The -o option tells minicom not to send the modem initialization string. 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 v4.1.0 ***
   Hello World! bl604e_iot_dvk/bl604e20q2i
   

Congratulations, you have bl604e_iot_dvk configured and running Zephyr.
