Beagle Experiments

For more comprehensive look into the combined world of Beagle+open source, see to the provided here:

There’s an example of a DSP node for the dsp-bridge:
http://github.com/felipec/dsp-dummy

It’s simply sending buffers back and forth.

There are instructions about how to get all the tools, compile, and
run it at:
http://elinux.org/BeagleBoard/DSP_Howto#Developing

Also,the GStreamer/OpenMAX IL specific stuff is at:
http://elinux.org/BeagleBoard/gst-openmax

This is not following TI’s documentation, which I find overly
complicated. There are a few tricks to avoid the usage of extra tools,
headers, and messy dependencies, which actually don’t seem to work
anyway.

Enjoy!

Reliable libbridge

Use this version of libbridge:
http://omapzoom.org/gf/download/frsrelease/117/724/dspbridge_mpu_api.tar.gz

The IRQ -33 is a different issue and a kernel patch is available to
workaround it:
http://marc.info/?l=linux-omap&m=122349732218782&w=2

Many have realised this to be a reliable patch.

DSP Binaries

You must have seen the elinux DSP How to at

http://elinux.org/BeagleBoard/DSP_Howto

But the readymade binaries are at

http://people.freedesktop.org/~felipec/beagle/beagle-gstreamer-dsp.tar.bz2

except the DSP nodes, which you need to download, install
and accept the license agreement yourself.

These binaries work with systems compiled with latest images from
codesourcery (arm-2007q3), just put them on /opt and do the following:
export PATH=$PATH:/opt/gst/bin
export LD_LIBRARY_PATH=/opt/gst/lib:/opt/omx/lib
export GST_PLUGIN_PATH=/opt/gst/lib/gstreamer-0.10

Also the kernel stuff:

http://people.freedesktop.org/~felipec/beagle/bridgedriver.ko

http://people.freedesktop.org/~felipec/beagle/linux-2.6.27-rc7-omap1-05018-g43

The following gst-omapfb element is used to render YUV data
efficiently on the beagle:

Enjoy!

TMSC64X DSP

I’ve started looking for the high-end multimedia processer +C64X in the beagle.

The processors needs

(1)a linux based DSP compiler

(2)a DSP bridge

(3)kernel driver and other tools

They are collectively repo’ed at the following link:

http://elinux.org/BeagleBoard/DSP_Howto

I doubt if we use the compiler for linux separately for DSP, whether JTAG is needed or not…Also the demo version of CCS is not supporting JTAG and other emulation tools.
