Introduction
The Overlay is a tar file that includes modified versions of processor configuration dependent files that are required by various toolchain tools, such as binutils, gcc, and gdb. The overlay described here has a specific layout and is intended for toolchain generators, such as buildroot or crosstool-NG.
Creating the overlay
The overlay file shipped by Tensilica uses a flat directory structure, which is not suitable for buildroot or crosstool-NG at the moment. It is part of the generated processor package, and can be found in the XtDevTools directory:
XtDevTools/install/build/$VERSION/$XTENSA_CORE/src/xtensa-config-overlay.tar.gz
The following script converts the directory structure of that file by creating a new overlay file, called xtensa-overlay.tgz, and extracting the necessary files from the Tensilica overlay. Simply provide the path and name of the overlay provided by Tensilica when running the script:
./script xtensa-config-overlay.tar.gz
This will create the file xtensa-overlay.tgz required by buildroot or crosstool-NG. For more information how to configure those generators, please see Buildroot or crosstool-NG.
