Tool/software:
I am trying SCI peripheral in F2800137 mcu.
I replicated the sci_ex2_loopback_interrupts example on my project.
But my Rx interrupt is only triggered once and then it would never been triggered again, while my Tx interrupt was working well.
I tried to config my project exactly as the example, and now I do not see any difference between them.
And I tried both internal and external connections between Tx and Rx Pin.
Here are my configs


and here is my code:

Did anyone meet this problem before? please let me know.
And I noted that when I increase the FIFO level for interrupt my received package seemed to be not in the correct order, Can anyone explain this to me?
Thanks for reading.
