### [`bootloader`](https://github.com/stnolting/neorv32/tree/master/sw/bootloader)
|
|
|
|
Source(s) of the default NEORV32 bootloader. A pre-built image is already installed into the rtl design via the
|
## [bootloader](bootloader)
|
`rtl/core/neorv32_bootloader_image.vhd` file.

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

### [`image_gen`](https://github.com/stnolting/neorv32/tree/master/sw/image_gen)
|
|
|
|
This folder contains a simple program that is used to create NEORV32 executables (for upload via bootloader) and VHDL memory

|
initializiation 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.

|
|
|
|
NEORV32 RISC-V Architecture Test Framework.
|

|
### [`lib`](https://github.com/stnolting/neorv32/tree/master/sw/lib)
|
|
|
## [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.
