Hi,

   We are using LPC1756 DMA interface on UART1 module. We are able to get DMA interrupt for transmit packets. Also we are getting the RX DMA interrupt for number of bytes same for RX FIFO level.

   However, whenever we send less bytes than RX FIFO level we are not receiving DMA timeout interrupt.

Please suggest if you have any solution.lpc175x
