Lpc2000

Hi to all group members,
                         Iam using LPC2214 for my project.
 i am using external memory for my project.Iam getting some problems 
with my .ld file.Coz i dont know how to write it.I have an .ld file wc
which is deined for internal flash and ram.But i have to define one 
more segment for External memory.
          so plese some body can send .ld file which is used for 
three memory regions(flash,ram and external  memory ranging from 
0x80000000).
    Thanks in advance.
