Hmm. I don't think so. See:

---------------------------
This is precompiled version
---------------------------
nickolay@nickolay:~/IXP425$ arm-elf-objdump --private-headers 
redboot_RAM.elf
redboot_RAM.elf:     file format elf32-bigarm
Program Header:
   LOAD off    0x00008000 vaddr 0x00020000 paddr 0x00020000 align 2**15
        filesz 0x00026f9c memsz 0x0003603c flags rwx
private flags = 202: [APCS-32] [FPA float format] [software FP] [has 
entry point]

---------------------------
This is builded version
---------------------------
root@nickolay:/opt/ecos/build3# arm-elf-objdump --private-headers 
install/bin/redboot.elf
install/bin/redboot.elf:     file format elf32-bigarm
Program Header:
   LOAD off    0x00008000 vaddr 0x00080000 paddr 0x00080000 align 2**15
        filesz 0x0002600c memsz 0x00034420 flags rwx
private flags = 402: [APCS-32] [VFP float format] [has entry point]


This is how i building redboot:

root@nickolay:/opt/ecos/build3# /opt/ecos/ecos-2.0/tools/bin/ecosconfig 
--srcdir=/opt/ecos/ecos-2.0/packages/ new ixdp425 redboot
U CYGSEM_HAL_USE_ROM_MONITOR, new inferred value 0
U CYGIMP_HAL_COMMON_INTERRUPTS_USE_INTERRUPT_STACK, new inferred value 0
root@nickolay:/opt/ecos/build3# /opt/ecos/ecos-2.0/tools/bin/ecosconfig 
--srcdir=/opt/ecos/ecos-2.0/packages/ import 
/opt/ecos/ecos-2.0/packages/hal/arm/xscale/ixdp425/current/misc/redboot_RAM.ecm
root@nickolay:/opt/ecos/build3# /opt/ecos/ecos-2.0/tools/bin/ecosconfig 
--srcdir=/opt/ecos/ecos-2.0/packages/ tree
root@nickolay:/opt/ecos/build3# make &> make.out

root@nickolay:/opt/ecos/build3# ls -l install/bin/
итого 1788
