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®ards!
zhlg
