Linker Flags in NiosII IDE

Could anyone tell me what I'm doing wrong?

My aim is to place an array at a particular address, as an example 0x10000.

Help files descibe one way of declaration section as a linker flag 

--section-start SECTION=ADDRESS

I set 
--section-start FRAME=0x10000

and in с file 

char Frame __attribute__ ((section ("FRAME")));

But the linker says: 

nios2-elf-g++: FRAME=0x10000: No such file or directory

I've missed something, haven't I?

Regards

    I've managed it!

    In autogenerated file generated.x I added the section description 

    SECTIONS
{
    ............................
    . = 0x10000;
    .frame : { *(.frame) }
}

    And here it is! The array Frame[] is placed at 0x10000

    It's a good idea to browse through Redhat's website, as well....for any of the binutils (http://sources.redhat.com/binutils/) tools. The syntax of linker scripts is covered here....

    For those who really want to know how it works.
