Loading DSPLink Module on xM

For the last couple of days am trying to setup the DSP side of DM 3730
on my Beagleboard-xM (Rev A3) with a Angstrom 2011 build.
During boot, the kernel message shows

so i made a look into "/usr/share/ti/gst/omap3530/loadmodules.sh" ,
which shows

#!/bin/sh

Did you use boot.scr to set the memorymap?

Did you use boot.scr to set the memorymap?

No, jost copied the MLO, u-boot.bin & uImage from /boot of the
Angstrom image to 'boot'(Primary, FAT32 partition)

The ram of the XM needs to be partitioned/reserved.
A portion reserved for linux. Another for DSP.

To do that you need a script that tells the initial bootloader to do
that.

Google mkimage boot.scr setenv beagleboard.
You'll find a tutorial.
