uClinux detects less RAM memory than I have

Hi all, 

 

Can anyone explain me why uClinux detects less RAM memory than I have? I have a 16 MBytes SDRAM, but uClinux can see just 12,2 MBytes. I apologize if this is a stupid question. 

 

I already tried to force "mem=16M" in <Processor type and features> --> <Default kernel command string>, but with no results. 

 

Thanks in advance  

 

Marco
