The LayGO PDK is distributed as a gzipped tar file which includes the C and C++ include files, static libraries and object files necessary to build eCos programs for the PXS. Also included are several test programs and makefiles. To install, simply extract the distribution file to a directory. For instance, to install the PDK in /opt:
mv laygopdk-3.10.tar.gz /opt cd /opt tar xzf laygopdk-3.10.tar.gz ln -s laygopdk-3.10 laygopdk
Finally, if you want to use the PDK makefile system to build either the PDK test programs
or your own programs, create an environment variable in your shell named
PDKHOME containing the path to the PDK install directory. For
the Bourne shell, place this line in your .bashrc file:
export PDKHOME=/opt/laygopdk
PDF documentation for the eCos operating system is located in the doc/ecos
directory.
arm-elf Toolchain
The GNU arm-elf toolchain is required to build programs using the
PDK. Source and binary RPMs are located on the Advanced Relay web site.
Typically, you will only need to install the following 3 binary RPMs:
Download the RPMs to /opt/laygopdk/tools/linux.
You need to be root to install the RPMs:
# su Password: # cd /opt/laygopdk/tools/linux # rpm -v --install *.rpm # exit
By defualt, the RPMs install the tools into /usr/local/bin.
Make sure this directory is included in your PATH environment variable.
If you are using the Cygwin environment on Windows, the tools are packaged together in arm-elf-tools.tar.gz.
PDF documentation for the tools in the arm-elf toolchain is available for
download in gnu-tools-doc.tar.gz.
