Help required for the dsp bridge

Hello All,
I would like to change the EXTMEM to suit my codec requirements using
the DSP bridge on beagle board.
Currently, I modified dsp/tconf/modules/shm.tci as follows:
if(dspbridge.module("BRIDGE").C64P)
{
....
_EXTMEMSIZE=0X0120030C
.....
}
and the changes got refelcted in ddspbase_tiomap3430_x64p.map,
         name origin length used unused
attr fill

Hi Aparna,

I have no experience with DspBride. I'm using good old DspLink instead.
Without looking much at your case I have a vague idea what might go wrong.

Just a question: Does the error happens all the time, or does it work
once and the problem starts the second/third time youcommunicate with
the DSP. If this is the case I may be able to help.

Cheers,
    Nils

Hello Nil,

Thanks for the reply..
Ya the error happens every time I run the ./cexec.out
This has to be run because otherwise the processor doesn't get
attached and the applications wont work...
Please help me out...

Aparna

Hello Nil,
   Just one more thing to discuss...

     I'm trying to integrate H.264 codec into the dspbridge and
     I'm successful running the arm side.
     But when I try to run the DSP side it is giving the
     following error:
           error:cant allocate .far, size 0100030c (page 0) in EXTMEM
           (avail: 003e0000)
           When I got this error, I tried updating the EXTMEM with
0100030c
           by changing the value 003e0000..
       Then this error was solved but... then when I run on the board
I'm getting the oher error(./cexec.out..)
   root@beagleboard:/home/trials# ./cexec.out ../test_dsp/
       ddspbase_tiomap3430.dof64P

          DSP device detected !!
         ////////DSPProcessor_Start succeeded.---->this statement is
missing
        Hit any key to terminate cexec.
So this is the whole thing...
Please guide me... !!
Regards and Thanks
Aparna

Sorry, i can't help you. I'm only using dsplink, not dsp-bridge.

If the DSP would have worked on the first try but hanged on subsequent
runs I would have had a good candidate and possible solution for the
problem.

Good luck,
