[okl4-developer] linking boot image

[Nelson Tam]

Hi Tomas,

If you look closely, the elfadorn command actually contains a call to  
the linker (ld).  The -Ttext option is actually passed to the linker,  
not elfadorn.  If you take a look at the linker man page, you'll find  
that -Ttext determines the absolute address that the .text section  
will be linked to.  This is important because the bootloader should  
start execution from this very address after bootstrap.

Of course, depending on your setup, it is possible to change this  
address and still have a working system (for example, simply telling  
the bootloader to start at a different address).

Which platform are you working on, and what linker is being used?

Nelson.
