Configuration

Please use efm32pg_stk3401 ID for board option in “platformio.ini” (Project Configuration File):

[env:efm32pg_stk3401]
platform = siliconlabsefm32
board = efm32pg_stk3401

You can override default SLSTK3401A Pearl Gecko PG1 settings per build environment using board_*** option, where *** is a JSON object path from board manifest efm32pg_stk3401.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:efm32pg_stk3401]
platform = siliconlabsefm32
board = efm32pg_stk3401

; change microcontroller
board_build.mcu = efm32pg1b200f256gm48

; change MCU frequency
board_build.f_cpu = 40000000L

Uploading

SLSTK3401A Pearl Gecko PG1 supports the next uploading protocols:

  • blackmagic
  • jlink
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:efm32pg_stk3401]
platform = siliconlabsefm32
board = efm32pg_stk3401

upload_protocol = mbed

Debugging

Debugging - “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).

SLSTK3401A Pearl Gecko PG1 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
