LP-MSPM0G3507: UART DMA interrupt multiple byte TX RX to and from console

Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: SYSCONFIG

Hi TI. i am developing on application with lpmspm0g3507 . Trying to send and receive data to and from console using UART. and for that i am using two example codes. .UART tx dma interrupt and uart rx dma interrupt. but after running i am stuck at first transition only.  my question is . is it possible do UART tx rx at same time using DMA? if i configured bot interrupt for DMA will it work together?  also if i  am combining two different example codes as mentioned above what sysconfig setting i need to do?

    Hi Mehul,

    You should be able to do this, sending and receiving console data via UART. You mean like the UART external loopback example, but using DMA instead of manually moving the received character into the TX buffer?

    The interrupts should continue to work fine as long as you enable them and set them up correctly. 

    In Sysconfig, you should just make sure that the settings for both the TX and RX are applied.  There is no special consideration to make when you are trying to merge two of our existing examples.

    You may want to try starting with our UART external loopback example, and then adding in the DMA functionality.
