[ECOS] On ecos startup squeue:copy vectors

[zhlg_shuhan]

Hi all.
  1. in file vectors.s of ppc,Firs copy vectors to 0x0000(if nessesary)but at this point,RAM was not inited,so how to acess address 0x0000?
  2.in one file I have found two ".text" ,no subsection following.
so these two parts code will be located where individually?
  3."__exception_\name@L",i guess @L means lower half of a 32 bit address,but i can't get detailed info from assembler.
  4 many symbols,such as:
                __bss_start
                 __bss_end
                __sbss_start
                __sbss_end
 appeared in both *.ld and *.ldi,but could you tell me  how compiller to use these two files ?
and these two files' roles in whole project?
                                                     
tks&regards!
