Hi all,

I have DMA working with UART on the embedded artists board. However, I want to echo each characted received as well as the usual processing on received strings.

I mainly want DMA for the transmitted data since there is a lot of it. Not much data will be received. Is it possible to use DMA for transmitted data but interrupts for received data? Or is there a way of getting an interrupt for each byte when receiving by DMA?

Any ideas?
