NEORV32 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.
isa-test
NEORV32 RISC-V Architecture Test Framework. See sim/README.
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.
