Getting the "Hello world" example on the A8 running

Jane Perera78562

I have installed VM Virtual box and the SDK on my pc and have compiled the example "Hello world" for the a8.  Now I want to boot the Linux file system from my development host as outlined in the EZ software developer's guide.  I changed the environmental variables  as so:

setenv autoload no

setenv bootfile uImage

setenv ipaddr 10.0.x.x (address from ifconfig command result shors inet addr:)

Then I boot up (Type "boot" from serial console window). 

After that I was expecting to be able to see the executable that I moved to the VirtualBox directory targetfs/home/root/dm816x in the directory /home/root/dm816x of the EVM

but I do not.  see it there.  Did I miss something else I need to do?  Is there a quick way to exchange files between the systems.  Ftp and sftp do not work.

    Following is my configure commands, and it can work correctly. 

    setenv ipaddr 192.168.9.180

    setenv serverip 192.168.1.253

    setenv gatewayip 192.168.1.1

    setenv bootcmd 'tftpboot 0x81000000 uImage_dvr;bootm 0x81000000';

    setenv bootargs 'mem=128M console=ttyO2,115200n8 root=/dev/nfs rw rootfstype=jffs2 nfsroot=192.168.1.253:/home/dvrsdk/target/rfs ip=192.168.9.180:192.168.1.253:192.168.1.1:255.255.0.0::eth0:off varm=20M'

    boot
