Problem about dm8168 ramdisk filesystem boot param when use 2g ddr

Hi all:

I develop on dm8168 board use dvrrdk4.0, and i use ramdisk file system 

and now i want to use 2048M ddr for my application,

but when i set the boot params like follow ramdisk(32M) boot:

setenv bootargs 'mem=512M console=ttyO2,115200n8 root=/dev/nfs rw nfsroot=root=/dev/ram0 rw initrd=0x82000000,40M ramdisk_size=450000 ip=192.168.1.101:192.168.1.175:192.168.1.1:255.255.255.0::eth0:on vram=20M notifyk.vpssm3_sva=0xbfb00000 vmalloc=476M ddr_mem=2048M earlyprintk'

it fails when i set initrd=0xC0000000 it boots,but load.sh run error,

How to set the boot params then?

I have set the uImage boot from 0xc0008000 ,

mkimage -A arm -O linux -T kernel -C none -a 0xc0008000 -e 0xc0008000 -n 'Linux-2.6.37' -d arch/arm/boot/zImage uImage_DM816X_UD_DVR

as NFS is like follow which works ok
setenv bootargs 'mem=512M console=ttyO2,115200n8 root=/dev/nfs rw nfsroot=192.168.1.175:/root/nfs_target/rfs_816x ip=192.168.1.101:192.168.1.175:192.168.1.1:255.255.255.0::eth0:on vram=20M notifyk.vpssm3_sva=0xbfb00000 vmalloc=476M ddr_mem=2048M earlyprintk'

best regards

    Can you try with ramdisk_size=45000?

    http://processors.wiki.ti.com/index.php/TI81XX_PSP_User_Guide

    TI8168_EVM# setenv bootargs 'mem=200M console=ttyO2,115200n8 root=/dev/ram0 initrd=0x82000000,40M 
                          ramdisk_size=45000 ip=dhcp'
TI8168_EVM# bootm 0x81000000

    Regards,
