I could boot the SAMA5D3-Xplained board using the 'arm-v7a-linux-gnueabihf’ config of OSELAS toolchain 2014.12.0.

I’ve done a custom config based on the 'arm-cortexa8-linux-gnueabihf' toolchain. I had to remove the 'PTXCONF_GLIBC_EXTRA_ADDONS="cortex-strings”’ option. Please check the attached file and the diff’s.
Warning: I’m no expert in toolchains. Although it seems to run fine, I haven’t done much testing. It might be safer to go with the standard 'arm-v7a’ config.

Regards,
Jean-Claude
