Kashin lin,
I assume you are trying to communicate between ARM & DSP using DSPLink.
You can refer to sample applications provided with the DSPLink release
as a reference for how the APIs can be used. The sample applications are
available within the /dsplink/gpp/src/samples and
/dsplink/dsp/src/sa
Hello,
I try to change the memory map of the DSP to enlarge the DDR.
It looks like this:
baselen end
LINUX 80003D09000 83D09000
HEAP83D09000BCF7000 8FA0
DDR 8FA020

JFTR: To solve this problem I had to rebuild the dsp-libs!

when the gstreamer v4lsrc plugin opens the davinci /dev/video0 driver it
calls ioctl with VIDIOCGCAP to get the capabilities. When i run this it
returns with EPERM. does anyone know why this is happening.

Hi,
thanks for your reply.
i still have some questions:
i have had a look at the samples and user guide in DSPLink. it has a
directory(DspBios) includes dsp/bios application in each sample
(message, loop...) and we can build them in DSPLink make system. but without
telling how to create the dsp/b
Hi,
i got a error when building dsp/bios link and need some help.
the environment of the building:

perl version: 5.8.8

i modified some variables
Thank you Ashuari,
Could you or somebody tell me how I would go about setting the virtual
resolution for the frame buffer. Just looking through the davincifb.c code
it doesn't seem obvious. The IOCTL commands don't seem like they can
accomplish it. Is there any written documention on the davincif
Ok, I've figured out how to set the Virtual Resolution using ioctl commands
and/or fbset utility.
Now I'm having a hard time understanding the yres_virtual parameter. The
xres_virtual parameter seems to be doing what I think it should. For example
if I have an 720x480 image being displayed on the

When a dma channel is opened, clear all pending events.
This was causing problems if UBOOT initialized the SDCard.

Hello,
I need some help to mount/umount MMC card when my application is running.
I don't have any problem to mount/umount It manually.
I have also another problem with mmc card, It is not detected correctly on
booting the OS (error to read the sector 0)
thank you.

Can you build with VERBOSE=1
gmake debug VERBOSE=1
With this, you will get prints of all the commands during make, and will know
exactly which one is failing.

Kashin Lin,
The method doesn't really differ that much ... By using our own make
system, we enable easy building on different targets, and also enable
the same build system to be used for Linux-based build. However, we use
the same tool-chains & DSP/BIOS. The final generated executable when you

Hi All,
ITCM/DTCM of ARM subsystem has been enabled in the U-boot. Is there a way to
