 GNU Toolchains

 ^^^^^^^^^^^^^^

 

-The build logic in these directories assume that you are using the GNU

-toolchain with the Atmel patches.  The patch file, pre-patched tool sources,

-and pre-built binaries are available from the Atmel website.

+Atmel Toolchain:

 

-  CONFIG_AVR32_AVRTOOLSW=y  # Use the windows version

-  CONFIG_AVR32_AVRTOOLSL=y  # Ue the Linux version

+  The build logic in these directories assume that you are using the GNU

+  toolchain with the Atmel patches.  The patch file, pre-patched tool

+  sources,and pre-built binaries are available from the Atmel website.

 

-NOTE: The NuttX builtroot cannot be used to build the AVR32 toolchain.

-This is because the Atmel patches that add support for the AVR32 are not

-included in the NuttX buildroot.

+WinAVR:

+

+  Another option for use under Windows is WinAVR:

+  http://sourceforge.net/projects/winavr/files/.  WinAVR includes the

+  AVR32 toolchain as well as the AVR toolchain and various support

+  libraries and header files.
