Hi,

I have implemented a UART interrupt handler, basically it handler is invoked on a RX interrupt.When ever am sending a character from terminal it is calling handler ,but it is stuck there(am not clearing interrupt in handler,after it returns from handler i cleared interrupt), please guide me how to solve this problem.

Hi Surya,

How did you implemented handler. In which API it stuck? When are you clearing interrupt as it is asynchronous call. It should be done in handler only.
