Use the following links to download and install the software, if not already installed: Additionally 4 jumper wires are needed.Ĭonnections are as below: Raspberry Pi Pico SWD Connection Setup & Tools I’m using the JTAG/SWD breakout board from Adafruit. The Raspberry Pi Pico includes a 3-pin debug header with GND, SWDIO and SWDCLK:īecause the Pico does not use a standard 2×5 pin debug header, I have to connect the pins including VCCsense with an adapter board. I’m using here the J-Link EDU Mini which is well worth the $20. Hardware ConnectionĪs debug probe, any J-Link can be used. While this is great, there is an easy way to use any existing J-Link and Eclipse IDE too, so this is what this article is about. There are plenty of tutorials out there, for example how to use the Pico board as debug probe to debug another Pico board. It can be easily used with C/C++ or MicroPython, and the Raspberry Pi Pico board only costs around $5. It is a very versatile microcontroller, with a rich eco-system and set of tools. Raspberry Pi Pico with J-Link, with a NXP sensor board The RP2040 is the first microcontroller from Raspberry Pi: a dual-core ARM Cortex-M0+ running up to 133 MHz, 264 KByte on-Chip RAM and up to 16 MByte external FLASH. It is not only inexpensive, it is (at least for now) available which makes all the difference. So it is not a surprise that the Raspberry Pi RP2040 gets used more and more in projects. In this time where many micro-controllers have 100+ weeks estimated delivery time, it makes sense to look at alternatives.
