All testing has been conducted using the NuttX buildroot toolchain. However,

the make system is setup to default to use the Code Red toolchain. To use

the CodeSourcery, devkitARM, or buildoor toolchain, you simply need add one

If you are not using CONFIG_LPC17_BUILDROOT, then you may also have to modify

the PATH in the setenv.h file if your make cannot find the tools.

NOTE: the CodeSourcery (for Windows), devkitARM, and Code Red (for Windows) are

Windows native toolchains. The CodeSourcey (for Linux), NuttX buildroot and

Code Red (for Linux) toolchains are Linux native toolchains (The buildroot may

Code Red IDE

------------

Code Red is a Eclipse-based that is highly tuned from the LPCxxx MCUs. You

Execute-Only Build
|

------------------
|

|

You should be able configure Eclipse to simply load the NuttX executable built
|

outside of Code Red: Files->import->C/C++->C/C++ Executable.

Makefile Build
|
||||
--------------
|

|
||||
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
|
||||
simply use the NuttX makefile to build the system. That is almost for free
|
||||
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
|
||||
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
|
||||
there is a lot of help on the internet).

------------

I should be possible to build NuttX as a "normal" IDE project. I do not

trying. But here are a few tips before you start such an effort:

2) Start the NuttX build at least one time from the Cygwin command line

Startup files will probably cause you some headaches. The NuttX startup file

Using Code Red GNU Tools from Cygwin
|
||||
------------------------------------
|
||||
|
||||
Under Cygwin, the Code Red command line tools (e.g., arm-non-eabi-gcc) cannot
|
||||
be executed because the they only have execut privileges for Administrators. I
|
||||
worked around this by:
|
||||
|
||||
Opening a native Cygwin RXVT as Administrator (Right click, "Run as administrator"),
|
||||
then executing 'chmod 755 *.exe' in the following directories:
|
||||
|

/cygdrive/c/nxp/lpcxpreeso_3.6/bin, and

/cygdrive/c/nxp/lpcxpreeso_3.6/Tools/bin
