Hi,
Do you use source from SVN head ?
Yes.
Do you have any information in obj-ppc/build.log ?
This is somewhat interesting:
powerpc-440-linux-gnu-strip openbios-qemu.elf
BFD: st4PszLi: warning: allocated section `.bss' not in segment
BFD: st4PszLi: warning: allocated section `.sbss' not in segment
The "nostrip" version of openbios-qemu.elf looks much better:
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x000094 0xfff00000 0xfff00000 0x42044 0x4bcb4 RWE 0x4
LOAD 0x0420d8 0xfffffffc 0xfffffffc 0x00004 0x00004 R E 0x1
GNU_STACK 0x000000 0x00000000 0x00000000 0x00000 0x00000 RWE 0x4
Section to Segment mapping:
Segment Sections...
00 .text.vectors .text .rodata .data .sdata
01 .romentry
02
So something goes wrong in the strip process.
