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.
JLink¶
To connect to the QuickFeather board with JLink please follow instructions in the QuickFeather User Guide 4.
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
