Hi Sugar,

the toolchain you need is the one with the aarch64-linux-gnu triplet.

Hi yvan, I saw linaro have released gcc-linaro-arm-linux-gnueabihf-4.9-2014.08_linux.tar.bz2. I have compiled cortex-a53 by 'arm-linux-gnueabihf', but its binary is 'ELF 32-bit LSB executable', not 'ELF 64-bit'. Is it only compile to aarch32? If I want to compile aarch64, which toolchains I should choose? Or what options should pass to compiler.

Thanks.
