When targetting the ec555 board it is possible to build

the system for either RAM bootstrap or ROM bootstrap. RAM

bootstrap generally requires that the board

is equipped with ROMs containing a suitable ROM monitor or

equivalent software that allows GDB to download the eCos

ROM monitor may process exceptions or interrupts generated from the
