Arduino Zero (Programming/Debug Port)

System

Platform Atmel SAM: Atmel | SMART offers Flash- based ARM products based on the ARM Cortex-M0+, Cortex-M3 and Cortex-M4 architectures, ranging from 8KB to 2MB of Flash including a rich peripheral and feature mix.

Microcontroller

SAMD21G18A

Frequency

48MHz

Flash

256KB

RAM

32KB

Vendor

Arduino

Configuration

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

[env:zero]
platform = atmelsam
board = zero

You can override default Arduino Zero (Programming/Debug Port) settings per build environment using board_*** option, where *** is a JSON object path from board manifest zero.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:zero]
platform = atmelsam
board = zero

; change microcontroller
board_build.mcu = samd21g18a

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Arduino Zero (Programming/Debug Port) supports the next uploading protocols:

  • cmsis-dap

  • blackmagic

  • jlink

  • atmel-ice

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:zero]
platform = atmelsam
board = zero

upload_protocol = cmsis-dap

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

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).

Arduino Zero (Programming/Debug Port) has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
