I have loaded a raw image of MPC 8548 CDS (6.4.1) on 8548 board. The board came up and able to ping using tsec0 
interface.

From qnx prompt, when I try to get a file using tftp, it is saying "No such file or directory" error.

We ensured that the tftp server is running and file also present in tftp server. because same server setup is used to 
load the image from uboot. In /etc/services file tftp entry also present.

Please suggest me, if I miss anything.

The following is log info from MPC8548 board:
