Projet_SETI_RISC-V/neorv32/sw

Software Framework

This folder provides the core of the NEORV32 software framework. This is a short description of the main folders.

bootloader

Source(s) of the default NEORV32 bootloader. A pre-built image is already installed into the rtl design via the rtl/core/neorv32_bootloader_image.vhd file.

common

NEORV32-specific common files for all bootloader and application programs: linker script for executable generation and processor start-up code.

example

Several example programs for testing and for getting started.

image_gen

This folder contains a simple program that is used to create NEORV32 executables (for upload via bootloader) and VHDL memory initialization files (for memory-persistent applications and for the bootloader). This program is automatically compiled using the native GCC when invoking one of the application compilation makefiles.

lib

Core libraries (sources and header files) and helper functions for using the processor peripherals and the CPU itself.

ocd-firmware

Firmware (debugger "park loop") for the on-chip debugger. This folder is just for documenting the source code. Modifying the sources is not recommended as this could break the on-chip debugger.

openocd

Configuration file for openOCD to connect to the NEORV32 on-chip debugger via JTAG.

svd

Contains a CMSIS-SVD compatible system view description file including all peripherals.
