I have tested the same code using a big-endian qemu with the cortex-strings tests which are taken from glibc: http://bazaar.launchpad.net/~linaro-toolchain-dev/cortex-strings/trunk/view/head:/tests/test-memcpy.c I haven't built glibc big-endian yet, but I can do that if you think it would be valuable. -- Will Newton Toolchain Working Group, Linaro
