ℹ️ All setups using open-source toolchains are located in the osflow folder. See the README there for more information how to run a specific setup / configuration.

Adding Your Project Setup

Please respect the following guidelines if you'd like to add (or link) your setup to the list.

• check out the project's code of conduct
• add a link if the board you are using provides online documentation (and/or can be purchased somewhere)
• use the 📁 emoji (:file_folder:) if the setup is located in this repository; use the 🌍 emoji (:earth_africa:) if it is a link to your local project
• please add a README to give some brief information about the setup and a .gitignore to keep things clean

Setup-Specific NEORV32 Software Framework Modification

In order to use the features provided by the setups, minor optional changes can be made to the default NEORV32 setup.

• To change the default data memory size take a look at the 📚 User Guide section General Software Framework Setup
• To modify the SPI flash base address for storing/booting software application see 📚 User Guide section Customizing the Internal Bootloader
