Configure the debugger and chip and you are in business.
- To Debug Code:
- Debugging the NuttX Object File:

will be recognized by the file menu.
Select the project name, the full path to the NuttX object (called
just nuttx with no extension), and chip. Take the time to resolve
all of the source file linkages or else you will not have source

toolchain options.
1. The CodeSourcery GNU toolchain,

4. The NuttX buildroot Toolchain (see below).
The NuttX make system can be configured to support the various different

toolchain. To use alternative toolchain, you simply need to add change of
the following configuration options to your .config (or defconfig) file:

NOTE about Windows native toolchains
------------------------------------
The CodeSourcery (for Windows), Atollic, and devkitARM toolchains are
Windows native toolchains. The CodeSourcery (for Linux), NuttX buildroot,
and, perhaps, the generic GCC toolchains are Cygwin and/or Linux native
toolchains. There are several limitations to using a Windows based
toolchain in a Cygwin environment. The three biggest are:
There are basically three kinds of GCC toolchains that can be used:
1. A Linux native toolchain in a Linux environment,
2. The buildroot Cygwin tool chain built in the Cygwin environment,
3. A Windows native toolchain.
There are several limitations to using a Windows based toolchain (#3) in a
Cygwin environment. The three biggest are:
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
performed automatically in the Cygwin makefiles using the 'cygpath' utility
but you might easily find some new path problems. If so, check out 'cygpath -w'
performed automatically in the Cygwin makefiles using the 'cygpath'
utility but you might easily find some new path problems. If so, check
out 'cygpath -w'
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links
are used in Nuttx (e.g., include/arch). The make system works around these
problems for the Windows tools by copying directories instead of linking them.
But this can also cause some confusion for you: For example, you may edit
a file in a "linked" directory and find that your changes had no effect.
That is because you are building the copy of the file in the "fake" symbolic
directory. If you use a Windows toolchain, you should get in the habit of
making like this:

An alias in your .bashrc file might make that less painful.
3. Dependencies are not made when using Windows versions of the GCC. This is
because the dependencies are generated using Windows pathes which do not
work with the Cygwin make.

NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
-Os.
NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that
