MCBSP operation - hing...@arlut.utexas.edu - Oct 27 8:27:48 2006



Hi, I am having trouble with the mcbsp. Whenever I use the following code in my main
program - 
"MCBSP_start(hMcbsp1, MCBSP_SRGR_START | MCBSP_SRGR_FRAMESYNC, 0x300u);
MCBSP_start(hMcbsp1, MCBSP_XMIT_START, 0x0u); "

my interrupts are disabled and my interrupt service routines won't work. I am pretty sure that
the 2nd line is what is disabling my interrupts, because when I comment out that line my isrs
get serviced, but then of course my output to the mcbsp1 doesn't work without that line. Even
when I try to enable interrupts after this code they still don't get enabled.  Any suggestions
would be greatly appreciated. Thanks.
