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. Vendor information…

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:

Drivers ¶

Windows:

Start debugging session using PlatformIO IDE. PlatformIO will install J-Link software dependencies
Navigate to home_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.

Frameworks ¶

Name	Description
Arduino	Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
CMSIS	The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices.
ESP-IDF	Espressif IoT Development Framework. Official development framework for ESP32.
libOpenCM3	The libOpenCM3 framework aims to create a free/libre/open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC 11xx, 13xx, 15xx, 17xx parts, Atmel SAM3, Energy Micro EFM32 and others.
mbed	The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.
Simba	Simba is an RTOS and build framework. It aims to make embedded programming easy and portable.
SPL	The ST Standard Peripheral Library provides a set of functions for handling the peripherals on the STM32 Cortex-M3 family. The idea is to save the user (the new user, in particular) having to deal directly with the registers.
STM32Cube	STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency.
