i use objcopy as follow(the brec_flash is elf file)
        mipsel-linux-objcopy -O binary brec_flash brec_flash.bin

i use mipsel-linux-objdump -h brec_flash and get messages as follow


brec_flash:     file format elf32-tradlittlemips

Sections:
Idx Name          Size      VMA       LMA       File off  Algn

                  CONTENTS, ALLOC, LOAD, READONLY, DATA, LINK_ONCE_SAME_SIZE
  5 .pdr          000011a0  00000000  00000000  0001ca88  2**2

                  CONTENTS, READONLY
  7 .comment      000000ea  00000000  00000000  0001dc28  2**0

                  CONTENTS, ALLOC, LOAD, READONLY, DATA

the 0x72xxxxxx should be 0xa2xxxxxx, because i can't pass by set
0xa2000000,so i change the .text to 0x72000000, and it can get the
.bin correctly.
