In the past three days I'm trying to figure out how to enable OMAP3530
DSP.
According to Jserv diagram http://jserv.blogspot.com/2009/09/0xdroid-beagleboardomap3.html,
it's really clear I need to find and build OpenMAX IL & DSP Bridge
library / drivr. & DSP codec binary.
Then I found TI has release these software needed.

http://gitorious.org/ti-dspbridge
https://gforge.ti.com/gf/project/openmax/frs/

I have download these packages and build successful.

My question is

1.What else should I do to get it work with 0xdroid ? (Maybe it's a
complex task, sorry to ask such a question.)
2.The 0xdroid shell leaks of "mknod" to create dspbridge device node.
How to create device node runtime ?
3.What about gstreamer & gst-openmax, do I need it ?

hi Steve,

I'm glad to hear someone interested in the enablement of OMAP353x DSP.

Yes, it is supposed to be integrated into OMAP Android:

[...]

OMAP Android did it, but it is mainly dedicated to Zoom2 hardware as
far as I know.

You can either
(1) use statically-linked busybox
(2) modify init/devices.c to add the node

You don't need them at least for Android integration.

Steve,

Though my answer is not specific to 0xdroid, here is my comment wrt
(q3).

If you are using Android/GStreamer build, (documented here -
http://labs.embinux.org/index.php/Android_For_OMAP3_with_Gstreamer_In...
), you should be able to use GstOpenmaxIL and DSP transparently as
GStreamer abstracts rest of the software stack / hardware.

Hi All

I do get DSP works, Thanks.

Also I found some problem would like let you know.
The DSP doesn't work with last version dsplink-1_61_03 and 0xkernel
because the default 0xkernel config enables <OMAP 3 Camera Support> &
<IOMMU Support> and blocks IRQ 28 which required by DSPLINK.
