Hi Guillermo,

With the "cortex-strings" enabled, it crashed somewhere in the boot process. I assumed this option provided some optimised functions using NEON instructions. However I never verified exactly what that option does. Maybe someone else can clarify?
What hardware do you use? SAMA5D3 lacks NEON instructions, but SAMA5D4 does support it.
'cortex-strings' seems to be enabled in the 'arm-v7a-linux-gnueabihf' of 'OSELAS toolchain 2013.12.2', but disabled in more recent versions of the toolchain.
Regards,
Jean-Claude
