TMS320F28388D: UART Echoback example not working in F28388D

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi,

I deployed the following example from c2000Ware 5.02 

1) uart_Config_C28x to the cpu1 core of the F2838x

2) uart_ex1_echoback to the arm core of the F2838x.

I am using an FTDI cable connecting the Tx and Rx pins of the FTDI cable to the Rx(Pin 152-GPIO85) and Tx(Pin 151 - GPIO84) respectively.

This is how I am getting the putty output

 

These are my COM Port settings:

I am not sure what I am doing wrong. Could someone please guide me?

Thanks,

Mukul

  • Hi Mukul,

    Can you verify that you are using the correct COM port? To do this you can open the Device Manager on your PC and check which COM port has a UART connection. For example, in this screenshot I would use COM 27:

       

    In most cases it would be the highest numerical COM port number.

    Also, can you verify that your cm_common_config_c28x.c file configures GPIO84 and GPIO85 and that you are running that .out on the main CPU before running the other .out on the CM core? The main CPU has to be run first to boot up the CM core.

    Best Regards,
