[U-Boot-Users] vmlinux kernel image(IN ELF BINARY format) for making uImage

[Swapnil Ashok Narkhede]

Hi,

I have several doubts.

1>>
The README of U-boot says
for generating uImage we have to get
vmlinux image in ELF BINARY FORMAT.
How do i know if the vmlinuz image that 
i have is in ELF BINARY format?
2>>
I have a vmlinux image compiled 
from MontaVista Linux for COnsumer
Edition. The size of this image is
28 MB but when i use this image in
generating uImage the linux.bin that is genrated 
is of 1.7MB and after gzipping it and finally
making uImage the uImage is of 775Kb.
How is this possible?
What is exactly happening out here?
Is it a right way to pass MontaVista Kernel
image to Uimage?
Why is there so much of reduction in size?

Please help me clear this concept
