GNU Toolchain Options
|
||||
=====================
|
||||
|
||||
As of this writing I have used only the CodeSourcery GCC toolchain for windows.
|
||||
As of this writing, all testing has been performed using the NuttX buildroot
|
||||
toolchain described below. I have also verified the build using the
|
||||
CodeSourcery GCC toolchain for windows. Most any contemporary EABI GCC
|
||||
toolchain should work will a little tinkering.
|
||||
|
||||
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-M0 toolchain, one can be downloaded from the NuttX
|
||||
SourceForge download site (https://sourceforge.net/projects/nuttx/files/buildroot/).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||
|
||||
cd tools
|
||||
./configure.sh nutiny-nuc120/<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/cortexm0-eabi-defconfig-4.6.3 .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
|
||||
details PLUS some special instructions that you will need to follow if you are
|
||||
building a Cortex-M3 toolchain for Cygwin under Windows.
