From 6f71dcb7cdaff53d8b44ea7c13ddb48d274663e7 Mon Sep 17 00:00:00 2001 From: Hesham ALMatary Date: Thu, 21 May 2015 17:53:53 +0100 Subject: Epiphany: Add the first epiphany_sim BSP v4 This BSP in intended to run on the simulator that should be built from RSB. When building RTEMS for Epiphany --disable-networking must be provided part of the configure command. --- c/src/aclocal/rtems-cpu-subdirs.m4 | 1 + c/src/lib/libbsp/epiphany/Makefile.am | 8 +
