We are using LPC4357. We are connecting USART1 to an embedded ethernet module. We would like to set up DMA for that connection. Right now, we have set up DMA for receive path (that is when ethernet module receives a packet, we use DMA). When we setup transfer size as 10, we get a DMA interrupt after 10 bytes. Right now, we are using a test software and we send more than 10 bytes. However, the packet size varies. We would like to get DMA interrupt after receiving the entire packet. Any idea?
