Just get the most recent release from here http://buildroot.uclibc.org/downloads/buildroot-2014.11.tar.gz and use load following configuration in "menuconfig": --->--- BR2_arcle=y BR2_TOOLCHAIN_BUILDROOT_LARGEFILE=y BR2_LINUX_KERNEL=y BR2_LINUX_KERNEL_DEFCONFIG="fpga" BR2_PACKAGE_PERF=y BR2_TARGET_ROOTFS_INITRAMFS=y --->--- Then say "make" and you'll see the problem. If you experience any problems trying to follow my advice please let me know and I'll try to help you. -Alexey
