This article covers the Raspberry Pi RP2040 device, an arm Cortex-M0+ dualcore MCU with up to 133 MHz Clock. It is the first MCU designed and published by Raspberry Pi. The RP2040 is present on the Raspberry Pi Pico evaluation board.

Features (selection)

Stat Specification
Core Dualcore M0+
RAM 264kB SRAM
Internal flash No internal flash (ext. QSPI supported)
Pins (multifunc) 30 GPIOs
Pins (dedicated) 6 SPI IOs

J-Link Support

The Raspberry Pi RP2040 is fully supported by J-Link. Support was implemented with J-Link Software Pack V6.96.

Note:There seems to be a chip specific issue when trying to reconnect to the target device or if you switch connecttion to the second core. Instead of power cycling this can be solved by connecting Reset (Pin 15) from the J-Link to Pin "RUN" (Chip enable/Reset) of the RP2040.

Evaluation boards

There are multiple RP2040 evaluation boards. For all of the ones listed below, sample applications are available.

Sample projects

SEGGER Embedded Studio provides a RP2040 board support package for the RP2040 Pico. It is easily adjusted to all other available RP2040 boards, especially, as the QSPI pin-out is not modifiable. Additionally, the articles listed under Evaluation boards all provide sample applications.
