Apache NuttX RTOS on FPGA

This repository contains information and reference designs for running Apache NuttX RTOS on FPGA devices. Only Open-Source tools are considered. When ready this repository should be integrated similar way to nuttx-apps.

Software

Open source toolchain for AMD Xilinx devices: openXC7
For other devices, particularly Lattice ECP5: OSS CAD Suite
