Today we completed the publication of the last remaining Epiphany SDK source tree repositories to the Adapteva GitHub account, including all the drivers and library files. The two repositories can be found at: http://github.com/adapteva
epiphany-sdk
This repo is the master archive that integrates the various Epiphany-SDK components into a release/installation tree. It contains the master eSDK build script (build-sdk.sh) and some non-binary and non-runtime critical components like the documentation and examples.
epiphany-libs
This repo contains all the Epiphany SDK source code (minus the the Epiphany GNU compiler and binutils which can be found in the Parallella GitHub repository)
1. The e-hal library (the Epiphany Hardware Abstraction Layer, or simply “driver”), which is required to transfer data from the host to the Epiphany and back;
2. The e-loader library used by a host application to load a program to the Epiphany accelerator;
3. The e-xml library, which is the parser of an .xml text file (“Hardware Description File” – HDF) containing information about the hardware platform;
4. The e-server, which is our implementation of a remote-serial-protocol (RSP) gdb debug server, used to bridge between the e-gdb frontend and the hardware. The gdb <-> server communications works over TCP/IP and enables remote debugging of an Epiphany program;
5. The e-lib library, which is the Epiphany run-time library;
6. The e-utils directory, which contains wrapper scripts for some GNU binutils.
7. The bsps directories, which contain the files specific to each system configuration – HDF, LDF’s and a driver.
The epiphany-libs repo contains a master build script, called build-libs.sh that builds the above packages. Each buildable package is given as an Eclipse project that one can import to an Eclipse workspace for convenience.
All source repos are released under the GNU Public License v3 (GPL) or Lesser GPL (LGPL). See the license files in each project for specific licensing details.
Note that the repos reflect the current, in-the-works status of these packages, and will be modified in the future. Also note that in order to obtain the complete eSDK, one needs to download the Epiphany GNU sources, currently posted at the Parallella GitHub page. In the near future, we will integrate these packages within one streamlined build package.
Enjoy!
