Bare-Metal Demos

Bare-metal example projects for the Efinix Sapphire SoC.

These demos cover a wide range of functionality — from basic UART communication and GPIO interrupts to Dhrystone benchmarking and multi-core processing. Each example is self-contained and includes a makefile with complete C source code.

The following guides provide step-by-step instructions for setting up and executing each demo:
