Hi,

I'm trying to get the arm-elf-gcc cross-compiler from GNUARM.org 
(2008-10-19) to generate a binary for me, however I get an empty binary 
file out of objdump. The best conclusion I can draw is that my linker 
command isn't working right.

The compiler generates the listings right, so I can only assume the 
objects are correct. Judging by the output of arm-elf-size, it looks 
like objdump is doing its job alright as well. Through arm-elf-size, I 
seem to be missing the data, text, and bss sections. These really ought 
be there.

I've posted my linker script (taken and lightly modified from 
at91sam7s_example_gamma) as well as what happens when I attempt to 
compile the executable to http://pastebin.com/d6c63a237.

To clarify two things, I intend to target the AT91SAM7SE256, however 
right now am just sticking to the AT91SAM7S512/AT91SAM7S-EK.

Can anyone help me out?

Thanks,

Hi,

The -ffunction-sections and -fdata-sections did the trick. It's good to 
know about the unused code removal points as well.
