Raspberry Pi Pico Build Prerequisites

Prior to building a no-OS project for Raspberry Pi Pico, it is required to install the Pico SDK and debugging tools.

Note

Pico platform builds are supported on Linux only.

Prerequisites

  • Clone the Raspberry Pi Pico SDK.

  • Set the PICO_SDK_PATH environment variable to the pico-sdk cloned repository path:

    $ export PICO_SDK_PATH=/path/to/pico-sdk

  • Install the J-Link software.

  • Set the JLINK_SERVER_PATH environment variable to the JLinkGDBServerCLExe path (the default path should be /opt/SEGGER/JLink/JLinkGDBServerCLExe):

    $ export JLINK_SERVER_PATH=/opt/SEGGER/JLink/JLinkGDBServerCLExe

  • (Optional) For visual debugging and building, install Visual Studio Code, and the Cortex-Debug extension.

Building a project

To build a project, type:

$ make PLATFORM=pico

The build process creates a build directory in the project folder:

build
├── app
├── bsp
├── obj
├── project_name.elf
└── tmp

Running/Debugging

Once the .elf file has been generated, make sure the board is powered on, cable connected and use the following commands to upload the program to the board:

$ make run
