Dear Sir.

Thank's your advise. It is very useful to me.

My work log is see below.

  poplinux@raw rangeley $ > ./tools/ifdtool -x ./oem_dumped.bin
  File ./oem_dumped.bin is 8388608 bytes
    Flash Region 0 (Flash Descriptor): 00000000 - 0000ffff
    Flash Region 1 (BIOS): 00010000 - 007fffff

    Flash Region 3 (GbE): 00fff000 - 00000fff (unused)
    Flash Region 4 (Platform Data): 00fff000 - 00000fff (unused)

The Flash Region 2~3 is (unused). Is it corrent?


And descriptor.bin's content is see below.
