Getting Started with MCU+ SDK

The MCU+ SDK is only a dependency when:

Building OpenPRU projects that include code for an MCU+ core
Building OpenPRU projects, where the PRU firmware includes code in the MCU+ SDK (such as macros)

Install the MCU+ SDK

Users can either install the prebuilt MCU+ SDK, or clone the MCU+ SDK repository. In general, we suggest using the prebuilt MCU+ SDK:

The prebuilt SDK is packaged specifically for a single device, so it takes up less hard drive space than the MCU+ SDK repo
The CCS files in the OpenPRU project need modification to work with the MCU+ SDK repository

The prebuilt MCU+ SDK installer can be downloaded here:

If the MCU+ SDK repository is used, please follow the steps on page Getting Started with the MCU+ SDK Repo

Note

Refer to the documentation associated with your specific SDK release

Install the versions of the tools that are listed in these pages:

MCU+ SDK docs > Getting Started > Download, Install, and Setup SDK and Tools
MCU+ SDK docs > Getting Started > Download, Install, and Setup CCS
- Developers using a Linux computer, make sure to follow the additional steps at "CCS Linux Host Support"
- If section Create Target Configuration says to “Bypass not used CPUs”, do NOT bypass the ICSS / ICSS_G cores. The CCS debugger cannot connect to a PRU core if the PRU core has been bypassed

The imports.mak file contains the information that the OpenPRU makefiles need in order to build on your computer.

Copy open-pru/imports.mak.default into a new file, open-pru/imports.mak.

For ease of use, the new imports.mak file is already excluded from git tracking.

Open imports.mak and update the settings based on your specific computer. Follow the UPDATE comments to see which settings need to be modified.

After the OpenPRU repository has been set up, refer back to the README for build steps.
