Trigger multiple DMA\'s off same event?

Started by Brian C. Lane November 23, 2005
Is it possible to trigger 2 DMA\'s off the same McBSP event?

Eg. McBSP codec receive event triggers a receive DMA which reads data
from that McBSP.

Same receive event triggers a different DMA that writes to a different
McBSP\'s transmit register.

Can this be done?

If it was just your program, I would say that it was trying to read
inaccessible memory ... from a bad pointer, or something like that. But if
the examples programs are doing the same, there may be bad memory on your
board. If you have the board test program, I would run it.
