# NEORV32 Software Framework
|
|
|
|
This folder provides the core of the NEORV32 software framework.
|
|
This is a short description of the main folders.
|
|
|
|
|
|
## [bootloader](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](common)
|
|
|
|
NEORV32-specific common files for all bootloader and application programs:
|
|
linker script for executable generation and processor start-up code.
|
|
|
|
|
|
## [example](example)
|
|
|
|
Several example programs for testing and for getting started.
|
|
|
|
|
|
## [image_gen](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](isa-test)
|
|
|
|
NEORV32 RISC-V Architecture Test Framework.
|
|
See [sim/README](../sim/README.md).
|
|
|
|
|
|
## [lib](lib)
|
|
|
|
Core libraries (sources and header files) and helper functions for using the processor peripherals and the CPU itself.
|
|
|
|
|
|
## [ocd-firmware](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](openocd)
|
|
|
|
Configuration file for openOCD to connect to the NEORV32 on-chip debugger via JTAG.
|
|
|
|
|
|
## [svd](svd)
|
|
|
|
Contains a CMSIS-SVD compatible system view description file including _all_ peripherals.
