hi all
I have a problem with my MCBSP on DM640 right after my software is loaded on
dsp. after my software is loaded, MCBSP wouldn’t work(it doesn’t
start xmit, rceive nor interrupts) until I restart the whole software by hand.
after the first restart is done, it works properly. can any one help me about
that?
thanks.

does MCBSP needs for an extra restarting the software to work?

Normally, when I have this problem, it is because something in my code
is out of sequence.
If operation A must be performed before operation B and your code
performs B before A, you get the correct sequence on the combination
of 1st and 2nd run. B-A..B-A contains the proper sequence A-B.
You need to carefully review your code - explaining it in detail to
someone else might help.
If all else fails, you might have to troubleshoot. Like load the
program, run it, halt it, and see if interrupts are enabled.
