A section is missing in S-Record

[Torsten Mohr <tmohr at s dot netic dot de>]

Hi everybody,

i configured, compiled and installed binutils-2.13 and gcc-3.2.1
for the target v850-unknown-elf on a linux host.

I'd like to use this tool chain for a NEC V850/SF1, an embedded
controller.  This controller has its interrupt vectors in the
range 0x0000 to 0x0340, so i wrote a v850.ld:

MEMORY
{
  vectors (rx) : ORIGIN = 0, LENGTH = 0x340
  rom (rx) : ORIGIN = 0x340, LENGTH = 0x40000
  ram (!rx) : ORIGIN = 0xffffb000, LENGTH = 0x2000
}

SECTIONS
{
  .vectors : { *(.vectors)} >vectors
  .rodata : { *(.rodata) } >rom
  .text : { *(.text) } >rom
....

In crt0.s i wrote:
	.section	.vectors
	.offset		0
	jr		start

When i link it all together i get this in the map file:


Memory Configuration

Name             Origin             Length             Attributes
vectors          0x00000000         0x00000340         xr
rom              0x00000340         0x00040000         xr
ram              0xffffb000         0x00002000         !xr
*default*        0x00000000         0xffffffff

Linker script and memory map


.vectors        0x00000000        0x4
 *(.vectors)
 .vectors       0x00000000        0x4 out/crt0.o

.rodata
 *(.rodata)


So the section vectors made it into the ELF file, but when i
try to generate an S-Record with this command:

v850-unknown-elf-objcopy -O srec --srec-forceS3 qwe.elf qwe.srec

There is NOTHING at address 0x0000, it all starts at 0x340.


Where are the interrupt vectors?


Thank you for any hints,
Torsten.
