Downloading the SDK

First, you should create a directory for your build environment, for example ${HOME}/epiphany-sdk. We will then extract the various parts of the SDK into this build environment, so that the final structure will look something like this:

epiphany-sdk/
   gcc/
   binutils/
   gdb/
   newlib/
   cgen/
   sdk/
   epiphany-libs/

These subdirectories can be retrieved from the adapteva github repositories, for example with: git clone https://github.com/adapteva/epiphany-gcc gcc.

However, the more convenient method of downloading the sources is to use this script.

wget https://raw.github.com/adapteva/epiphany-sdk/master/download-toolchain.sh
chmod +x download-toolchain.sh

# You can either download them as zip packages(faster)
./download-toolchain.sh

# Or, alternatively, you can clone the github repositories(significantly slower, but simplifies updates)
./download-toolchain.sh --clone

Note: Currently, if you use the script, epiphany-libs will not be downloaded automatically. You will have to additionally perform git clone https://github.com/adapteva/epiphany-libs.git.
