DVSDK on Angstrom

How to get the DSP-specific parts from DVSDK to run on Angstrom linux
that comes out-of-the box on a BeagleBoard-XM?

First step: dsplink kernel module.

root@beagleboard:/lib/modules/2.6.32# find |grep dsp
find |grep dsp
./kernel/drivers/dsp
./kernel/drivers/dsp/lpm_omap3530.ko
./kernel/drivers/dsp/dsplinkk.ko

After "modprobe dsplinkk" :

@beagleboard:/lib# dmesg |grep DSP
[ 1018.494140] DSPLINK Module (1.65.00.03) created on Date: Jan 25 2011 Time: 20:51:12


In the current DSVSK 4.03 :

So let's look at those first, see what they are.
