OMAP-L138 uPP DMA issue

Hi,

I currently have a CPLD passing data to the uPP of an OMAP-L138 processor. The port is controlled by the DSP.

I have two input buffers for the uPP which is used in a Ping-Pong fashion. Everything is working as expected. I would like to add a function that allows me to stop the uPP at any time, point it to a third input buffer and make it start a new window there.

 My question is this: Is there a quicker way of achieving this than by putting the uPP in a software reset?

Thank you in advance.

Regards, 

Reino
