GETTING UART INTERRUPT TWICE

Jump to solution

I am working with uart interrupt example given in SDK. I changed it to in normal mode and Rx FIFO threshold i kept 1 byte. I am observing following things

                             No of bytes sent   No Of interrupt received

                                     1                               2

                                     2                               3

                                     3                               4

                                     5                               6

What could be the reason.

And one more thing ...when i am just loading the .elf, i am getting interrupt twice(Here I disconnected the terminal still)

Hi,

Can you please check how many bytes are you received in the RXFIFO, are you confirming the number of bytes sent from console or received in RXFIFO.
