LPC1788 SDRAM GPDMA

Hi,

 

I'm trying to use GPDMA M2M transfers using an external SDRAM memory connected to an LPC1788. The idea behind this is to automate copy of data between 2 different buffers (front buffer and back buffer), in a video application.  There must be transferred 768000 bytes from one buffer to the other every time the apllication does the "buffer switching". Has anyone did it already? Is it possible? Could anyone post an example on how to configure the hardware? Should I use linked lists to enable transfers of more data?

 

Thanks in advance.
