Problems of UART on DM355

Hello:

      Is there anyone can provide some advice to solve my UART problems?

      We used dm355 for video codec. It seems everything is right at the beginning ,however after the system running for a while,perhaps several hours, the UART just hung up. The cpu is still running, and we can watch the live on the another PC in LAN. The UART keeps printing messages ,however we can't key in any words. In other words , the TX is OK but the RX hung up.

     Could anyone tell me how to solve it? Many thanks,

    We are encountering the same problem. When our board is used for 4 hours or more, the UART RX hung up. We still see TX send out debug msg. But RX is not responding to any input. Did you resolve this problem? Or could anybody help to resolve this?
