I am using LPC1763. Already verified the UART operation on my product. Now needs to use DMA for UART, especially UART0. Based on the example code provided by NXP, upated my source code. While I transmit data through UART0 by using DMA, I am not getting the expected data at the receive side of the other device. I am only receiving the value 0xFF. My message packet contains 0xFF as a first byte, maybe I am receiving only one byte data in the other side. Verified the transfer size set in the register, everything looks fine. Also to mention I am getting DMA interrupt for every Tx.
