J-LINK¶

SEGGER J-Links are the most widely used line of debug probes available today. They’ve proven their value for more than 10 years with over 400,000 units sold, including OEM versions and on-board solutions. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments. Official reference can be found here.

Configuration ¶

You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):

[env:myenv]
platform = ...
board = ...
debug_tool = jlink

If you would like to use this tool for firmware uploading, please change upload protocol:

[env:myenv]
platform = ...
board = ...
debug_tool = jlink

; SWD interface
upload_protocol = jlink

; JTAG interface
upload_protocol = jlink-jtag

More options:

Custom Server ¶

[env:debug_jlink]
platform = ststm32
framework = mbed
board = nucleo_f446re

debug_tool = jlink
debug_port = :2331

debug_server =
  /full/path/to/JLinkGDBServerCL
  -singlerun
  -if
  SWD
  -select
  USB
  -port
  2331
  -device
  STM32F446RE

Multiple debug probes ¶

In case there are several J-Link probes connected to the same host machine, it’s possible to specify the precise serial number of the desired probe to avoid erroneous device selection.

[env:nrf52_dk]
platform = nordicnrf52
framework = arduino
board = nrf52_dk
upload_flags =
    -SelectEmuBySN
    123456789

Drivers ¶

Windows

Start debugging session using PlatformIO IDE. PlatformIO will install J-Link software dependencies
Navigate to core_dir/packages/tool-jlink/USBDriver
Run InstDrivers.exe.

Mac

Not required.

Linux

Please install “udev” rules 99-platformio-udev.rules. If you already installed them before, please check that your rules are up-to-date or repeat steps.
