Detailed information about the board can be found in a QuickFeather repository 1.

Supported Features

The QuickFeather configuration supports the following hardware features:

Interface

Controller

Driver/Component

UART

on-chip

serial port

The default configuration can be found in the Kconfig file boards/arm/quick_feather/quick_feather_defconfig.

Connections and IOs

Detailed information about pinouts is available in the schematics document 2.

Programming and Debugging

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:

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

The QuickFeather OpenOCD config 3 can be found in the OpenOCD mainline repository.

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:

# From the root of the zephyr repository
west build -b quickfeather samples/hello_world
  • Connect to the target using either OpenOCD or JLink

  • Connect via GDB and load an ELF file:

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