strange memory reading on DE2

Hello everyone,

Board: Altera DE2 with cyclone2

NOMMU

Sysfile: system0.ptf from DE2_NET Example (v 1.6 Terasic Homepage)

System: uclinux from nios2-linux-20090730.tar up to date git version,

fresh build (make menuconfig, make)

I followed the InstallNios2Linux guides from nioswiki.

At bootup or after dmesg it says:

Memory available: 5012k/2898k ram, 0k/0k ROM (1938k kernel code, 960k data)

Thats a little bit strange to me ...

make vendor_hwselect SYSPTF=DE2_NET.ptf

Looks the following:

--- Please select which CPU you wish to build the kernel against:

(1) cpu_0 - Class: altera_nios2 Type: f Version: 6.0

Selection: 1

--- Please select a device to execute kernel from:

(1) sram_0

Class: sram_16bit_512k

Size: 524288 bytes

(2) sdram_0

Class: altera_avalon_new_sdram_controller

Size: 8388608 bytes

(3) epcs_controller

Class: altera_avalon_epcs_flash_controller

Size: 2048 bytes

(4) cfi_flash_0

Class: altera_avalon_cfi_flash

Size: 4194304 bytes

Selection: 2

Hmm whats the problem?

Is it a problem?

Feedback would be great!
