Nut/OS Directory Trees
This document describes how to install the Nut/OS development environment on Windows.
Source tree. With the Configurator you will later create sibling directories called build trees (e.g. nutbld-mega256) and application trees (e.g. nutapp-ctrl). This way different Nut/OS configurations for different platforms can be derived from the same source tree and can be used concurrently.
Sample applications, from simple system event or timer tests to FTP and HTTP servers.
ImageCraft project templates for the sample applications.
Architecture specific system code, device drivers, linker scripts, runtime initialization etc.
Application binaries will be copied to this directory with 'make install'.
Ethernut boot loaders.
Hardware independant C runtime routines. May be used for platforms without libc, but not used with the compilers listed above, as they provide their own.
Nut/OS configuration scripts, used by the Configurator.
C++ support, probably limited.
Hardware dependant C runtime routines, mainly I/O and date/time.
Device drivers, which are configurable for all platforms. These are just a few. Most drivers are not yet portable and are therefore located in nut/arch.
API documentation including copyright statements.
Nut/OS file systems.
Collection of all C header files, which are related to Nut/OS source files. You compiler may provide similar, in which case it is important, that this directory is searched first.
Pre-build Nut/OS libraries. You may try these, if your compiler somehow fails to create them.
Network related code. The TCP/IP stack can be found here.
Nut/OS kernel code and some useful APIs, which are not really needed by the kernel.
High level network code, like DHCP, HTTP etc.
Source code and binaries of various tools. Your PATH environment should point to nut\tools\win32 in the first place. For example, make.exe may be also included in your compiler package, but it may not work with the Nut/OS Makefiles, which sometimes use very specific features.
A few main tools are not located in the tools directory, but in the application folder.
Nut/OS Configurator. GUI tool to setup Nut/OS for your specific environment.
Command line version of the Nut/OS Configurator. Useful for automatic builds.
This tiny utility is new with Nut/OS release 4.2. It scans local networks for Nut/OS nodes and allows to configure them remotely. Provided, that the application activates this service.
