Hello all. I assume that I am not the first to ask this question. But first some facts: [tm-ppc]$ uname -a Linux ana 2.0.25 #2 Tue Nov 12 00:07:08 EET 1996 i586 [tm-ppc]$ powerpc-elf-ld -v GNU ld version 2.8.1 (with BFD 2.8.1) [tm-ppc]$ powerpc-elf-as -v GNU assembler version 2.8.1 (powerpc-elf), using BFD version 2.8.1 file koe.s: --------------------- .globl _start _start: addi r0,r0,0 ba hui hui: ba _start ------------------------- [tm-ppc]$ powerpc-elf-as -mregnames -m403 koe.s -o koe.elf Assembly works fine, nice... But, what causes the gnu ld to act like this: (three examples follow, note that only the address of text segment changes) 1) [tm-ppc]$ powerpc-elf-ld -Ttext 0xffff8000 -o x.elf koe.elf powerpc-elf-ld: x.elf: Not enough room for program headers (allocated 2, need 3) powerpc-elf-ld: final link failed: Bad value [tm-ppc]$ 2) [tm-ppc]$ powerpc-elf-ld -Ttext 0x0fff8000 -o x.elf koe.elf koe.elf(.text+0x4): relocation truncated to fit: R_PPC_ADDR24 text koe.elf(.text+0x8): relocation truncated to fit: R_PPC_ADDR24 text [tm-ppc]$ 3) [tm-ppc]$ powerpc-elf-ld -Ttext 0x00ff8000 -o x.elf koe.elf [tm-ppc]$ In example 3. ld works, but I really need to locate at 0xffff8000, not to 0x00ff8000. How can I relocate to 0xffff8000? PowerPC reset vector is at 0xffffffc, and would like to keep the ROM at 0xffff8000 ... 0xffffffff. Also, what is the .got section on the following disassembly? [tm-ppc]$ powerpc-elf-objdump --disassemble-all x.elf x.elf: file format elf32-powerpc Disassembly of section .text: 00ff8000 <_start>: ff8000: 38 00 00 00 li r0,0 ff8004: 48 ff 80 0a ba ff8008 <hui> 00ff8008 <hui>: ff8008: 48 ff 80 02 ba ff8000 <_start> Disassembly of section .sdata2: Disassembly of section .data: Disassembly of section .got: 01038010 <.got>: 1038010: 4e 80 00 21 blrl ... Disassembly of section .sdata: [tm-ppc]$ Regards, Ana
