DSPLink (DSP-side component was not initialized)

[Christian Tausch]

Hi beagleusers,

i am a student, currently working on sound-processing using the beagleboard in revision C4. 

Currently I try to explore the possibilities of the DSP-part of the OMAP SOC, but ran into problems.

my setup:

an angstrom image build from source using the setup-script and a custom image recipe:

<my-image.bb>

require x11-image.bb

IMAGE_INSTALL += "\

task-xfce46-base \

task-xfce46-extras \

ti-dsplink-module \

ti-dsplink-examples \

task-sdk-native \

alsa-utils \

"

export IMAGE_BASENAME = "image-20100712-beagleboard-xfce"

</my-image.bb>

X-Loader: Texas Instruments X-Loader 1.4.4ss (May 28 2010 - 03:38:15)

U-Boot: U-Boot 2010.03-dirty (Jul 11 2010 - 20:28:31)

I limit the memory used by the kernel with the following u-boot line:

optargs=mem=99M@0x80000000

For what i read, this should be the smaller variant that is also suiteable for devices with just 128 MB.

Loading the module with the shell-script in the dsplink example directory gives no error:

root@beagleboard:/usr/share/ti/ti-dsplink-examples# ./ti-dsplink-examples-loadmodules.sh 

You have 81456kB total memory for Linux

In every tutorial and howto i read about using dsplink, this worked out of the box without further configuration. 

What am i missing? Any ideas?

Thanks for the links. 

My error is mentioned in the first one: http://processors.wiki.ti.com/index.php/Troubleshooting_DSPLink_configuration_issues#Problem:_PROC_start_failed_with_configuration_mismatch.2Ffailure

Sadly the one with most possible causes. 

Maybe a inconsistent memory-map-setting between GPP and DSP. But if this is the cause shouldn't there be a useful default value in the sources? 

http://processors.wiki.ti.com/index.php/Changing_DSPLink_Memory_Map talks about a 1+1MB default configuration.

It obviously worked for the authors of the tutorials.

Somebody here, for whom it worked out-of-the-box without changing the memorymap?

Otherwise my next step would be to build the kernel and dsplink outside the oe-framework.

I think this is because the DSP doesn't support running different
programs one after another. This is pointed out, somewhat
cryptically, in section 9.4 of the DSPLink OMAP3530 install guide.
The DSP needs to be reset between program invocations, for example
using the LPM example utilities. (Thanks to Koen Kooi for pointing
this out to me a while back.)

Hmm, from what I see, CodecEngine power cycles the DSP (using LPM)
between loading different codec servers, so there is no need to run
LPM stuff manually.

[vladimir]

ah, of course that only applies to CodecEngine, for pure DSPLink
it is still needed...
