Why my olinuxino A13 has only 256MB

[Ted87]

I have Olinuxino which looks exactly as this one https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino/open-source-hardware. I mean 3 USB and no WI-FI.

However, on my serial console I have (also pay attention to last "M" Board: A13-OlinuXinoM ):

Why I have 256mb of DRAM?

What are you booting?  Are you sure it's not built to look only for (or to assume only) 256MB?

Also, is it reserving any RAM?

because you try to boot A13-OLinuXino-MICRO Debian image on A13-OLinuXino
