Overview

The QuickFeather development board is a platform with an on-board QuickLogic EOS S3 Sensor Processing Platform.

Hardware

  • QuickLogic EOS S3 MCU Platform
  • mCube MC3635 accelerometer
  • Infineon DPS310 pressure sensor
  • Infineon IM69D130 MEMS microphone
  • 16 Mbit of on-board flash memory
  • User button
  • RGB LED
  • Integrated battery charger

Detailed information about the board can be found in a QuickFeather repository_.

Supported Features

Connections and IOs

Detailed information about pinouts is available in the schematics document_.

Programming and Debugging

.. zephyr:board-supported-runners::

Flashing

The QuickFeather platform by default boots from flash. Currently the Zephyr port only enables loading the program directly to SRAM using either OpenOCD and a SWD programmer or SEGGER JLink.

OpenOCD

In order to connect to the target a SWD programmer supported in OpenOCD is needed. To connect to the board run:

.. code-block:: console

openocd -f /path/to/swd-programmer.cfg -f tcl/board/quicklogic_quickfeather.cfg -c "init" -c "reset halt"

The QuickFeather OpenOCD config_ can be found in the OpenOCD mainline repository.

To connect to the QuickFeather board with JLink please follow instructions in the QuickFeather User Guide_.

Debugging

To debug the QuickFeather board please connect to the target with either OpenOCD or JLink and use GDB distributed in Zephyr's SDK in arm-zephyr-eabi/bin directory.

To load basic sample via GDB:

  • Build the sample in an usual way:

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

  • Connect to the target using either OpenOCD or JLink
  • Connect via GDB and load an ELF file:

.. code-block:: console

/path/to/zephyr-sdk/arm-zephyr-eabi/bin/arm-zephyr-eabi-gdb target remote <port_number> file </path/to/zephyr.elf> load continue
