CCS/TM4C129ENCPDT: UART Char put hanging problem

George Mathew

Part Number: TM4C129ENCPDT

Tool/software: Code Composer Studio

Hi,

I  have successfully used UARTCharGet and UARTCharPut  for sending and receiving a small number of bytes less than the size of 16. Now I am sending more than 16 bytes and the UARTCharPut  function hangs indefinitely. What possible reason can explain this behaviour ?

Regards

George

    Hello George,

    Can you post the code used so I can test it on a LaunchPad?

    I have seen one other report of this but we were not able to verify the issue on our end though we never received full source code. Our attempts at recreation did not show an issue. I just tried doing the same at different baudrates and I haven't run into any issues with UARTCharPut.

    If I can get the code you used I can test it myself and debug from there, but until I see the issue it is really not possible for me to advise on what is going on here.
