DSK6711 is driven me crazy: CSL & McBSP0 problem!

Hi decent members,

I am working on my Master's Project, and having troubles with the DSK
I have to work on: TMS320C6711

One of my tasks consists in acquiring some digital data: I am thinking
about using the Jack Input from MotherBoard to get it done.

Therefore, I am trying to access McBSP0 with CSL tools: but it is
getting me crazy, I can't figure out how to make the McBSP0 work!
However, using the DaughterBoard PCM3003 and McBSP1 works perfectly
with CSL.

Following code is what I try to do to read MotherBoard's input and
send it MotherBoard's output.

As you can see, the code is not that long!

Please folks, any comment is appreciate. Regards!

Visitor,

In the recent history, say the last 6 months, there was a program posted on this e-list that
successfully used both the McBSPs.
It did not use the interrupts.
There was several comments about the source code that you might also read, as expressed in later posts.

It seems to me that the interrupts should not be enabled until after the interrupt vector value is
placed in the vector table.

BTW:
Shouldn't the interrupt routine end in a RTI (return from interrupt) instruction, not just run off
the end of the function?
I seem to remember that the mcbsp open function has three parameters and the read/write functions
have 2 parameters.
But my memory isn't perfect, so that code may be right.

It looks like a non maskable interrupt is being enabled, maybe I'm misunderstanding the line of code
(IRQ_nmiEnable();)

a question:
is the mcbsp0 routed to the motherboard jack that you mentioned?

Hi all,

I'm really interested in the program that Richard's speaking about. Could anyone re-post it please? (i can't find it)
Thank you very much

Miguel
