Can LPC18xx do DMA transfer from SRAM (USB) to external SDRAM (EMC) ?

There are no examples and the only time memory to memory DMA is mentioned in the user manual is to write to the GPIO ports.

If so, how do you setup a DMA transfer to EMC?

Perfect.  That did the trick.  I now have DMA running to my SDRAM.

Thanks

Hi MX21,
LPCopen has GPDMA speed example. It transfers data from memory to memory. You can use this example. Please see link below
