[ECOS] Question about RAM available

[ECOS] Question about RAM available

[cguwinds]

When I use redboot to boot my computer,
the RAM available is shown two RAM available.
My question list :
     1.Why RAM's available is "0x00084950-0x00000000" 
                     but not "0x00000000-0x00084950"?
     2.RAM's available "0x00000000-0x00000000" means what?
May someone give me a hand on it?
Waiting for your answers.
 
Sincerely,
winds.

Hi, there,

I have a AT91 ARM board with 256KB SRAM for data access (programme runs from
Flash memory) and a CS8900A Ethernet controller. I just wondered if it's
enough to run TCP/IP network?

Thanks a lot.

David

Have a read of
http://sources.redhat.com/ml/ecos-discuss/2001-07/msg00808.html

Tight, but potentially possible.
