Uhm. I am using a SAMA5D3 Xplained board (so no NEON). However Linaro's README file for the cortex-strings project states that these should also be available for CPUs without NEON support: https://git.linaro.org/toolchain/cortex-strings.git/blob/HEAD:/README As stated, I used the arm-v7a-linux-gnueabihf from OSELAS.Toolchain-2013.12.2 without any modifications or changes and the system boots and seems to work just fine. I'll keep an eye on this. It would be good to konw why cortex-strings was disabled in more recent versions of the OSELAS.Toolchain. Can someone shed some light here?
