Software Framework

This folder provides the core, hardware abstraction layer, drivers, etc. of the NEORV32 software framework.

  • 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.
