description "
When targetting the CME555 board it is possible to build
the system for either RAM bootstrap or ROM bootstrap. RAM
bootstrap requires that the MPC555 internal flash contains a
suitable ROM monitor or equivalent software that allows GDB
to download the eCos application on to the board. The ROM
bootstrap requires that the eCos application be blown into
the MPC555 internal flash array. Both types of startup require
the internal flash array to be enabled. Both startup types expect
the boards RAM to be present on CS0 and the external flash on
CS1. CS2 is not used by eCos and can e.g. be used for memory
mapped I/O by your application. Typical use of the board could be
to build GDB-stubs for ROM bootstrap, use AXIOM's monitor to
program it in internal flash, and then change the necessary
switches and jumpers to enable internal flash and get the memory
map right. Consult the CME555 manual to make sure you have all
jumper settings correct."
