The Parallella is an SBC with Xilinx Zynq SoC and 16-core Epiphany-III co-processor.

I had contributed a device tree for the Parallella to v3.17 (with a network/clock issue just reported by Olof Johansson to be investigated).

Recently I started packaging a gcc49 cross-compiler for the Epiphany - it succeeded building for x86_64 and armv7hl but doesn't compile a trivial C program yet. Investigating why, cleaning up the .spec files and finding a better home than home:a_faerber:epiphany is the scope of this project.

Additionally, packaging of host libraries for Epiphany deployment from the Parallella as well as target libraries for Epiphany development could be investigated.

Another related topic would be investigating USB support for the Parallella, based on patches from Xilinx.

Looking for hackers with the skills:

      Updated cross-epiphany-newlib package from downstream 1.20.0 to official 2.1.0.

      Found the remaining bug for cross-epiphany-gcc49: Not just the gcc target files shouldn't be stripped by OBS, also the newlib files (libc.a, libepiphany.a, etc.). With that fixed, a simple C program compiles now.

        While the packaged Epiphany SDK is not yet working with my upstream kernel, it seems to work with downstream 3.12 kernel.

          Turns out some clocks were not enabled. kernel patch

      The reported network issue did not occur during my Hackweek testing. The USB patches compiled and resulted in the device being recognized, but no OTG-attached devices showed up in lsusb.
