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
http://labs.embinux.org/index.php/TI_DSP_Bridge_Resources. (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

2009/02/17 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 beagleboard.org # setenv bootargs
console=ttyS2,115200n8 ramdisk_size=32768 root=/dev/ram0 rw

10. Follow README (see Step #2), ping.out works like a charm.
[root@(none) /]# ./bridgeinstall

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

DSPNode_run succeeded

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
Farazv.
Best regards,
Paul
