BeagleBoard/DSP Howto - Helps are needed


Sorry, my bad. I made the modules and modules_install in a wrong
directry which caused the error of "no target".

In the correct directory, I did
  make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm modules --> OK
but with some warning
  export INSTALL_PATH > OK
  make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm modules_install


The modules are insatlled in $HOME/MOD/lib/modules/2.6.28-omap1/

What should I do to install the modules to the SD card for BeagleBoard
to use?

Best regards,



Create a soft link “” to in your root file system.



boot, which I mentioned. Well that’s the story so far :slight_smile:
I really need to get the DSP working properly on Beagleboard and I’d
appreciate the help.


If you just need to do get DSP working even if with an older kernel like 2.6.27-omap1, I may be able to help you.




That'd be great, 2.6.27 would be good enough. I'd only need DSP and
drivers (which I had already in 2.6.22). looking forward to hearing


hi. paul

as you modules had been compiled out, please copy you $HOME/$MOD/lib/modules/2.6.28-omap1/

to you root file system /lib/modules/2.6.28-omap1/ . wish you DSP can be run as quickly as much.



Aren’t there any good howto tutorials to introduce the DSP seting up correctly?

More or less, it can be tested by many users, and not the one which is out of date.

any help and documents is welcome.



Are you implying that the one I wrote is "not good"? I just tried the
'outdated' instructions and it works just fine. Of course you need to
use 'v2.6.27-omap1'.

Is it not working for you? Then please specify what is not working.

Note that if you can't compile a vanilla 'v2.6.27-omap1' and make it
run, then of course the one with DSP patches wouldn't work either.
Same goes for 'v2.6.28-omap1' and my 'v2.6.28-tidspbridge' branch.

My guess is the problem is the Angstrom images expect an extremely
patched kernel. I'll try to provide a simple image, but in the
meantime Daniel Díaz is working on some recipes for Poky Linux AFAIK.

Wow, that is timing -- I was just sending you an email about that.

I've written a small HOWTO on getting a basic image (based on
Poky/OpenEmbedded) with a Kernel that includes DSP Bridge, and with
some useful packages included, such as OpenMAX and GStreamer plug-ins.
It's here:

This doesn't seem to work:


Should I give you the kernel image and DSP bridge drivers, or do you want help in building the kernel source I use. Either way, I can help you. By the way, I use the baseimage.dof from tiopenmax-0.3. And cross compiler I use is [1]. First DSP application I used is Felipe’s dsp-dummy application.





Thanks, Felipec, for trying this out.


This doesn't seem to work:
git clone git://
git checkout ddiaz/gitomapzoom

I tried this instead:
git clone git://
cd meta-texasinstruments
git checkout -b gitomapzoom origin/ddiaz/gitomapzoom

Noted. Corrected on the wiki.

Still, I'm getting this:
bitbake omap-image-min-gst

it to increase performance.

ERROR: Nothing PROVIDES 'omap-image-min-gst' (but '[]' DEPENDS on or
otherwise requires it)

My bad. I missed a "/conf/" in the path of the configuration. Instead of:
  cp -p $POKY/meta-texasinstruments/conf/misc/local.conf $POKY/build/local.conf
should have been like this:
  cp -p $POKY/meta-texasinstruments/conf/misc/local.conf

Wiki has been updated with your input.

Thanks and greetings!

Hello Jesslyn,

It would be great if you can provide a package (for the BeagleBoard)
includes a uImage, a file system contains DSP bridge drivers and all
the stuff needed to run ping.out and Felipe's Example dsp node.

If I don't ask too much, a uImage plus a RamDisk file (rd-ext2.bin)
for DSP bridge driver and application would make beginners' lives

Of course I also like to know how to build the all things myself. But
I would like to have something working before heading the long

Best regards,


Hi Paul,

Follow this link for the kernel and root file system. Use the root file system over NFS. It saves a lot of time.

Thanks for providing the package of resources. I am kind of busy
today. Please allow me to update you the test results tomorrow.

Best regards,



I'm using the latest files from
on a B5 beagleboard, I've tried to follow the steps you mentioned but
in steps 4 and 6 I got the following output:

I've tried using the following commands as recommended in

modprobe cmemk phys_start=0x88000000 phys_end=0x89000000
modprobe dsplinkk
modprobe lpm_omap3530

Does somebody have an idea of what could be the problem???

My SD card stops working maybe due to too many re-writes. I need to
get a new SD card. So I will update later, sorry.

Best regards,


hi, on the link , i can’t see nothing.

does it? or something else is wrong?

Hello Jesslyn,

Finally, I got my new SD card. And I got ping.out working finally.

I downloaded you package two days ago. SD card broken and could not
test until the new SD card arrived today. Bellow is my procedure..

1. Downloaded DSPBridgeResources.tar.bz2 from (but just
like Tang said, it is removed as I checked it today.)

2. On my Windows PC, I uncompress DSPBridgeResources.tar.bz2 with
WinRAR v3.7 to get uimage.dsp, target.tar.bz2 and README.

3. I run Utu 7.10 in a VMware Virtual Machine (VM) on my Windows PC.

4. Copy target.tar.bz2 to the Ubuntu VM, /home/jars/tmp.
       $ bunzip2 target.tar.bz2
       $ sudo tar xvf target.tar
   Then I get /home/jars/target

5. Make a RamDisk with 32Mbyte size
       $ dd if=/dev/zero of=rd-jessylyn bs=1k count=32768
       $ mkfs.ext2 rd-jessylyn

6. Mount the RamDisk and copy target/* to the root of the RamDisk
       $ sudo mkdir /mnt/jessylyn
       $ sudo mount -o loop rd-jessylyn /mnt/jessylyn/
       $ sudo cp -R target/* /mnt/jessylyn/
       $ sudo umount /mnt/jessylyn/

7. Gzip the RamDisk, then rename it to rd-ext2.bin
       $ gzip -9 rd-jessylyn
       $ cp rd-jessylyn.gz rd-ext2.bin

8. Copy the uimage.dsp in Step #2 and the rd-ext2.bin in Step #7 to
teh SD card. The card has files like
        2009/03/17 下午 05:50 16,740 MLO <--
downloaded from
        2009/03/17 下午 05:50 717,372 u-boot.bin <--
downloaded from
        2009/03/17 下午 05:49 9,808 x-load.bin.ift <--
downloaded from
        2009/02/17 下午 08:42 1,819,728 uImage <--
copied from uimage.dsp of Step #2
        2009/04/02 下午 08:26 10,566,254 rd-ext2.bin <--
copied from rd-ext2.bin of Step #7

9. Plug the SD card to my Beagle board and boot up. Remember to stop
the autoboot by pressing a key. In the U-boot console, set the
bootargs as
        Audio Tone on Speakers ... complete
        Hit any key to stop autoboot: 0
        OMAP3 # setenv bootargs
console=ttyS2,115200n8 ramdisk_size=32768 root=/dev/ram0 rw

        OMAP3 # run bootcmd

        mmcblk0: mmc0:616d SD01G 1006080KiB
        mmcblk0: p1

        [root@(none) /]#

10. Follow README (see Step #2), ping.out works like a charm.
        [root@(none) /]# ./bridgeinstall
        INFO: For help run script as ./install_bridge help
        /install_bridge: command substitution: line 38: unexpected EOF

        Ping: Id 1.000000 Msg 49.000000 Mem 2408232.000000

11. Felipe's dummy also works, but it will make the system in a loop
for a looooong time.
        [root@(none) /]# dynreg.out -r /lib/dsp/dummy.dll64P
        [root@(none) /]# dummy
        DSPNodeCreate succeeded
        DSPNode_run succeeded
        dmm_buffer_map: 0x12008

        dmm_buffer_invalidate: 0x12028
        dmm_buffer_flush: 0x12008
        dmm_buffer_invalidate: 0x12028

Finally, I got ping.out and dummy work, even the DSP system is not
built by myself. Thanks to all, especially to Jesslyn, Felipe and

Best regards,



I had to take down the link due to request from TI. Apparently it contained the DSP firmware which were not re-distributable. I am involved some other work these days. Please give couple of days time to upload the root file system without the TI proprietary DSP firmwares.



Who contacted you?

Isn't the situation the same for dsp-link firmware that AFAIK is being
distributed in Angstrom images?
