Hi ,
I don't know if this will help but is your board from spectrum digital? If yes,there was a thread in this group sometime back http://www.dsprelated.com/groups/c6x/show/12246.php.
So there is a limit on data transfer. I used labview for RTDX and I found that I could not transfer more than 253 bytes. (Strange number!!).

Thanks
Nishank

Hi,

I\'m reading the book of Rulph Chassaing, Digital Signal Processing and Applications with the C6713 and C6416 DSK.

I have C6416 DSK, CCS 3.1, Matlab 2007a and I have a little problem with the communication of matlab and DSK. The program is this of Example 9.4 page 311.

It seems that Matlab can not read from DSK since the command

outdata = readmsg(cc.rtdx, \'ochan\' ,\'int16\ ');

print the error

Read RTDX Channel: Timed out waiting for CCS to confirm completion.

and DSK can not read from Matlab since it stacks in the line

RTDX_read(&ichan, buffer,sizeof( buffer));

Is there anything I can do? I suppose also that the communication is through the internal JTAG of DSK, which is connected with my computer through a usb port.

Thanks in advance

Hi again,

Sorry for my ignorance but I'm trying to find out what's wrong and I can't.

I used the the Diagnostic RTDX tool from CCS 3.1 and it seems that it passes all the three tests.

So the problem must be from the side of Matlab...But what can I do?

Thanks in Advance
