Hi,

You are absolutely right. I am talking about ARM code located in start.S file. I am not able to figure out from from the referred link. I also consulted " http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044d/IHI0044D_aaelf.pdf " which talks about arm code relocation but it is also not helpful. It nowhere talks about ".rel.dyn" section which i referred to in my previous post. Can You provide any pointer from where i can get understanding of this section.

Regards,, Sandeep

Hi,

...

I am analyzing U-Boot code for "relocate_code" function. In this function after copying the text section and before clearing the bss section we are doing "fix .rel.dyn relocations". I want to know that what actually we are doing in this section of code. What does this section actually contains and what kind of fix we are doing in this. What are relative and absolute fix that we are doing in this section.

Any kind of help will we highly appreciated.

Hi Sandeep,

I assume you are specifically talking about ARM code in start.S? This code is an implementation of the relocation mechanism defined in the ELF specifications. Look up <http://en.wikipedia.org/wiki/** Executable_and_Linkable_**Format#Referenceshttp://en.wikipedia.org/wiki/Executable_and_Linkable_Format#References> for details.

Amicalement,

Albert.
