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
application on to the board. The ROM bootstrap typically
requires that the eCos application be blown into EPROMs or
equivalent technology."
