IT WORKS!!!!!!!!!!!

Kristiansen, you were right!, just moved the _bss_end=. lines from the
bottom of the lpc2368.ld to the line 45 and it works fine, no other
modifications needed. I wasn't understanding well your intructions
when i first readed your post, and that's why it wasnt working (my
fault).

Richard,

Do you want me to send the lpc2368.ld file? Maybe it can help other
people getting a demo running out-of-the-box.

Now its time to explore this wonderful piece of software :).

Thank you guys!.
