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 ?

for debuggung. You need an ELF file to load into GDB.

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

Yes, and you should read more of this book, and especially more of the U-Boot manual, too.

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?

You guessed wrong. Instead, read the documentation.
