Other Parts Discussed in Thread: SPRC234

Hi,

We are using TMS320C6455 DSP for our design and referring sprc234 CSL as a reference code.

But here, we dint find the code for McBSP used as a Serial port(UART).

Please share the code for McBSP interface used as a Serial Port or Let us know the configuration need to be done to work it has a Serial port(UART).

Regards,

Sujan Kumar

    Actually we don't have a exact McBSP to UART implementation but you can refer to the following document which helps to understand and make changes as per C6455.

    Hi Titus S,

    We have referred the same document and implemented the driver for McBSP to UART.

    But, we are facing issue on transmitting data from target board to PC.

    The transmitted and received data's are as follow

    Transmit data : "McBSP UART Testing"

    Received data  :"xxxxxUART Testing "

    As shown above, the data after the first space are receiving properly.

    If i don't give any space in my Transmit data, all the data's are received as a junk character.

    Please let me know the solution\ possible cases  for the issue.

    Regards,

    Sujan Kumar
