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 quick_feather 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
