[U-Boot-Users] 回复: About the u-boot (in ELF binary format)

[腾飞龙 <jinlongwei@gmail.com>]

Hi,
   As you said, one must download the .bin file to flash and not the
ELF file, and U-Boot is a boot loader and not an application programm
which can  be
run under Linux. then, what is the u-boot(in ELF binary format) for ?
  I red the book"Building Embeded Linux systems " written by Karim
Yaghmour,in section 9.5 it described like this:
  If you intend to debug U-Boot itself ,copy the ELF binary also:
  $ u-boot ${PROJECT}/images/u-boot-0.2.0
  Here ${PROJECT}/images is a directory to which u make a copy of the
relevant bootloader images. so, i guess the ELF file may be downloaded
to target to debug u-boot. Is it so and how does the file work?
  Thank you in advance!
