int _init_startup

(

void

)

Low-level initialization routine called during startup, before the main function.

This version comes in replacement to the default one provided by the Newlib add-ons library. Newlib add-ons' _init_startup only calls init_exceptions, but Newlib add-ons' exception and interrupt vectors are defined in the same section and Newlib add-ons' interrupt vectors are not compatible with the interrupt management of the INTC module. More low-level initializations are besides added here.

int main

(

void

)

Main function. Execution starts here.

Return values

42	Fatal error.
