UART DMA

Hello everybody,

Now I'm working for a project which is need data transfer from UART. My data are too many so the transfer speed is too long and make the processor stop working and cannot continue the calculation. I want to make the data from UART is saved directly to the RAM using DMA. Is that possible? Is there any tutorial to make it?

Sorry for my English, Thx before

I'm not aware if it is possible to DMA PS UART data directly to the DDR3. I don't think so. I have not seen any discussion or tutorial that shows how to do this.

If may be possible to put the UART controller in the PL and then design a wrapper around that PL function and DMA that into DDR3, but again, I have not seen that anyone has already done that.
