Question regarding VisualDSP++ 4.0

Started by Unknown February 20, 2006
HI guys,
I am working on project involving adsp-21160 and I am using VisualDSP++
4.0.
At my main file I have setup both the corresponding DMA channels (DMA
chaining) for receiving (SPORT0) and transmiting (SPORT1) and SPORTs. I
have setup the streams in order to simulate I/O:
Source Target                            Destination Target
TX1                                           File(output.dat)
FILE(input.dat)                           RX0
After several minutes I got the following message:
*** Sport0 input file hit EOF *** with PC at: 0x40456

which showed me that the input buffer is full (interrup). And here I
met problem. In order to continue the simution I found it is possible
to do it using only Step debug F11, but cause the core algorithm is
huge it is not so smart to press F11 a couple of times. I tried to use
F5 using several breakpoints but unsuccessfully.
Does anyone has had similar troubles?
Any ideas to simulate faster?

What exactly happened? What does "unsuccesfully" mean in this context? Please explain clearly why you say it is unsiccesfull, so someone around can help.
