* Fixed build of LM3X6918 using the CodeSourcery Windows native toolchain. There
were lots of issues with Cygwin paths and Cygwin symbolic links. These changes
may work with the devarmKIT as well, but that remains untested.

These copied directories make work a little more complex, but otherwise work well.

<li>
<b>Dependencies</b>
NuttX uses the GCC compiler's <code>-M</code> option to generate make dependencies. These
dependencies are retained in files called <code>Make.deps</code> throughout the system.
For compilers other than GCC, there is no support for making dependencies in this way.
For Windows native GCC compilers, the generated dependencies are windows paths and not
directly usable in the Cygwin make. By default, dependencies are surpressed for these
compilers as well.
</li>
<p><small>
NOTE: dependencies are suppress by setting the make variable <code>MKDEPS</code> to point
to the do-nothing dependency script, <code>tools/mknulldeps.sh</code>.
Dependencies can be enabled for the Windows native GCC compilers by setting
<code>MKDEPS</code> to point to <code>$(TOPDIR)/tools/mkdeps.sh --winpaths $(TOPDIR)</code>.

README
^^^^^^
Development Environment
^^^^^^^^^^^^^^^^^^^^^^^
Either Linux or Cygwin on Windows can be used for the development environment.
The source has been built only using the GNU toolchain (see below). Other
toolchains will likely cause problems.
GNU Toolchain Options
^^^^^^^^^^^^^^^^^^^^^
The NuttX make system has been modified to support the following different
toolchain options.
1. The NuttX buildroot Toolchain (see below).
2. The CodeSourcery GNU toolchain,
3. The devkitARM GNU toolchain, or
All testing has been conducted using the NuttX buildroot toolchain. To use
the CodeSourcery or devkitARM GNU toolchain, you simply need to build the
system as follows:
make # Will build for the NuttX buildroot toolchain
make CROSSDEV=arm-eabi- # Will build for the devkitARM toolchain
make CROSSDEV=arm-none-eabi- # Will build for the CodeSourcery toolchain
make CROSSDEV=arm-elf- # Will build for the NuttX buildroot toolchain
Of course, hard coding this CROSS_COMPILE value in Make.defs file will save
some repetitive typing.
NOTE: the CodeSourcery and devkitARM toolchains are Windows native toolchains.
The NuttX buildroot toolchain is a Cygwin toolchain. There are several limitations
to using a Windows based toolchain 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'
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 not 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:
make clean_context; make CROSSDEV=arm-none-eabi-
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.
Support has been added for making dependencies with the CodeSourcery toolchain.
That support can be enabled by modifying your Make.defs file as follows:
- MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+ MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
If you have problems with the dependency build (for example, if you are not
building on C:), then you may need to modify tools/mkdeps.sh
NOTE: The CodeSourcery toolchain (2009q1) may not work with default optimization
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
-Os.
NuttX buildroot Toolchain
^^^^^^^^^^^^^^^^^^^^^^^^^
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
different from the default in your PATH variable).
If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
This GNU toolchain builds and executes in the Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
cd tools
./configure.sh eagle100/<sub-dir>
2. Download the latest buildroot package into <some-dir>
3. unpack the buildroot tarball. The resulting directory may
have versioning information on it like buildroot-x.y.z. If so,
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
4. cd <some-dir>/buildroot
5. cp configs/cortexm3-defconfig-4.3.3 .config
6. make oldconfig
7. make
8. Edit setenv.h, if necessary, so that the PATH variable includes
the path to the newly built binaries.
See the file configs/README.txt in the buildroot source tree. That has more
detailed PLUS some special instructions that you will need to follow if you are
building a Cortex-M3 toolchain for Cygwin under Windows.

Toolchain
^^^^^^^^^
Development Environment
^^^^^^^^^^^^^^^^^^^^^^^
Either Linux or Cygwin on Windows can be used for the development environment.
The source has been built only using the GNU toolchain (see below). Other
toolchains will likely cause problems.
GNU Toolchain Options
^^^^^^^^^^^^^^^^^^^^^
The NuttX make system has been modified to support the following different
toolchain options.
1. The NuttX buildroot Toolchain (see below).
2. The CodeSourcery GNU toolchain,
3. The devkitARM GNU toolchain, or
All testing has been conducted using the NuttX buildroot toolchain. To use
the CodeSourcery or devkitARM GNU toolchain, you simply need to build the
system as follows:
make # Will build for the NuttX buildroot toolchain
make CROSSDEV=arm-eabi- # Will build for the devkitARM toolchain
make CROSSDEV=arm-none-eabi- # Will build for the CodeSourcery toolchain
make CROSSDEV=arm-elf- # Will build for the NuttX buildroot toolchain
Of course, hard coding this CROSS_COMPILE value in Make.defs file will save
some repetitive typing.
NOTE: the CodeSourcery and devkitARM toolchains are Windows native toolchains.
The NuttX buildroot toolchain is a Cygwin toolchain. There are several limitations
to using a Windows based toolchain 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'
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 not 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:
make clean_context; make CROSSDEV=arm-none-eabi-
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.
Support has been added for making dependencies with the CodeSourcery toolchain.
That support can be enabled by modifying your Make.defs file as follows:
- MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+ MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
If you have problems with the dependency build (for example, if you are not
building on C:), then you may need to modify tools/mkdeps.sh
NOTE: The CodeSourcery toolchain (2009q1) may not work with default optimization
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
-Os.
NuttX buildroot Toolchain
^^^^^^^^^^^^^^^^^^^^^^^^^
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
be modified to point to the correct path to the SH toolchain (if
be modified to point to the correct path to the ARM toolchain (if
different from the default).
If you have no SH toolchain, one can be downloaded from the NuttX
If you have no ARM toolchain, one can be downloaded from the NuttX
SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
1. You must have already configured Nuttx in <some-dir>nuttx.
