Initialisation source code

Hi all,

Does anyone know where to get the init() called in main.cpp (and for that matter the complete run time library) source code ?

I have downloaded and from but all they have are the same binaries as provided in


The init() function is in hardware/arduino/sam/variants/arduino_due_x/variant.cpp.

The GCC runtime library is in NewLib libc, which is part of any ARM Embedded GCC distribution.
