Hello, All
I am sure I have only 64M DDR Memory in my EVM board.
And
If I have only 64M DDR Memory in my EVM board,It seems that I sure set the
mem<=64M in the uboot, but I have set my mem=256M once and it boot the linux
successfully!Below is my setting of the uboot
##############################################################################
bootdelay=3
baudrate=115200
ethaddr=00:0e:99:02:51:46
netmask=255.255.255.0
rootpath=/home/beny/workdir/filesys
fileaddr=80700000
bootfile=DVEVM/uImage
ipaddr=dhcp
serverip=192.168.1.1
bootcmd=dhcp;bootm
serveip=192.168.11.1
gatewayip=192.168.11.1
nfshost=192.168.11.1
bootargs=console=ttyS0,115200n8,noinitrd rw ip=dhcp root=/dev/nfs nfsroot=192.16
8.11.1:/home/beny/workdir/filesys,nolock mem=256M
stdin=serial
stdout=serial
stderr=serial
###################################################################################
And when I enter in the Linux OS ,I use top command to check the memory,it
display like this:
#######################################################################################
Tasks: 25 total, 1 running, 24 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.7% us, 0.3% sy, 0.0% ni, 99.0% id, 0.0% wa, 0.0% hi, 0.0% si
Mem: 257180k total, 26844k used, 230336k free, 0k buffers
Swap: 0k total, 0k used, 0k free, 9344k cached
######################################################################################
It seems that the system has 256M physical Memory!
Why?How to explain this?
Thanks for any reply!
Regards!
