Hi, experts:

I am studying u-boo.bin format(which is got from u-boot, an ELF format bin).

I run the below command:

Objdump -h -b binary -m arm u-boot.bin

Found only a .data section was displayed.

So , does u-boot.bin include only a .data section?

u-boot.bin does not really include sections - it is just a binary file, not ELF format. It includes data from the .text, .data. and .rodata sections among others. You are telling objdump that it is an ARM binary file and asking it to print a list of sections. I suspect it creates a .data section just for fun - there aren't really any sections in the file. Of course if you examine the file you will see the contents of .text, .data, .rodata etc. from the original ELF format file, but the header information that distinguishes them is not present in u-boot.bin.
