Please use gapuino ID for board option in “platformio.ini” (Project Configuration File):

platform = riscv_gap
board = gapuino

You can override default GAPuino GAP8 settings per build environment using board_*** option, where *** is a JSON object path from board manifest gapuino.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = riscv_gap
board = gapuino

; change microcontroller
board_build.mcu = gap8

; change MCU frequency
board_build.f_cpu = 250000000L


Debugging - “1-click” solution for debugging with a zero configuration.


You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

GAPuino GAP8 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
