| |
| Overview |
| ******** |
| |
| The Raspberry Pi Pico 2 and Pico 2W are second-generation products in the Raspberry Pi |
| Pico family. From the `Raspberry Pi website <https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html>`_ is referred to as Pico 2. |
| |
| The Pico 2 supports running code on either a single Cortex-M33 or a Hazard3 |
| (RISC-V) core. |
| |
| As with the Pico 1, there's no support for running any code on the second core. |
| |
| Hardware |
| ******** |
| |
| - Dual Cortex-M33 or Hazard3 processors at up to 150MHz |
| - 520KB of SRAM, and 4MB of on-board flash memory |
| - USB 1.1 with device and host support |
| - Low-power sleep and dormant modes |
| - Drag-and-drop programming using mass storage over USB |
| - 26 multi-function GPIO pins including 3 that can be used for ADC |
| - 2 SPI, 2 I2C, 2 UART, 3 12-bit 500ksps Analogue to Digital - Converter (ADC), 24 controllable PWM channels |
| - 2 Timer with 4 alarms, 1 AON Timer |
| - Temperature sensor |
| - 3 Programmable IO (PIO) blocks, 12 state machines total for custom peripheral support |
| - Infineon CYW43439 2.4 GHz Wi-Fi chip (Pico 2W only) |
| |
| - Flexible, user-programmable high-speed IO |
| - Can emulate interfaces such as SD Card and VGA |

| Connections and IOs |
| =================== |
| |
| The default pin mapping is unchanged from the Pico 1 (see :ref:`rpi_pico_pin_mapping`). |

| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| The overall explanation regarding flashing and debugging is the same as for :zephyr:board:`rpi_pico`. |
| See :ref:`rpi_pico_programming_and_debugging` in :zephyr:board:`rpi_pico` documentation. N.b. OpenOCD support requires using Raspberry Pi's forked version of OpenOCD. |
| |
| Below is an example of building and flashing the :zephyr:code-sample:`blinky` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: rpi_pico2/rp2350a/m33 |
| :goals: build flash |
| :flash-args: --openocd /usr/local/bin/openocd |
| |
| The blinky sample is not yet supported on Pico 2W, so try the :zephyr:code-sample:`wifi-shell` application to connect to the network: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/net/wifi/shell |
| :board: rpi_pico2/rp2350a/m33/w |
| :goals: build flash |
| :flash-args: --openocd /usr/local/bin/openocd |
