GPDMA and EMC

Hi to all!

I'm using LPC1810 for my application.

Now I want to read data from an external SRAM and write those data to another SRAM.
To do this I have to use the EMC module.

I'd like to know if I could use the GPDMA module in order to transfer (read and write) data between external SRAM.

To do this, should I configure the GPDMA with a memory to memory DMA control?

Thanks in advance,
Giovanni.

Hi, Giovanni,

DMA with mem to mem between external SRAM should work.

Thanks,
