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!

I have successfully compiled u-boot and ,as you know, there areseveral object files produced after"make all", one of which is u-boot(in ELF binary format) . Now, i run the u-boot(in ELF binary format) in target board (Embedded Planet EP405)with Linux kernel and NFS file system. # ./u-boot then appears the error echo: Segmentation fault will you please tell me what's the problem and how to solve it?
U-Boot is a boot loader and not an application programm which can be run under Linux.
