BOOSTXL-AFE031-DF1: Can not connect to BOOSTXL-AFE031-DF1 GUI

Hi expert,

I am supporting my customer testing BOOSTXL-AFE031-DF1.

they follow the guide and program the code into F28004X launchpad.

they connect these two boards and connect to PC.

but it can not connect to the GUI.

using Putty to connect, it can communication. but it is not same with the guide. It always give NACK, when I input 'enter', and I can not input any other charactors 

and I also test with another C2000 demo code on uart. It can work fine. so the hardware of F280049 Launchpad is right.

do you think I missed somethin for HW or SW?

    Hi Emma,

    It has been some time since I've used this GUI, so it may take me a little time to remember some details.

    The initial things I can think of being the issue are the COM port settings (BAUD rate and such) or the F280049C LaunchPad's SCI GPIO hardware configuration. Please make sure your Putty serial settings match the below:

    • Use a serial terminal program (e.g. PuTTY) to configure the serial port (230400,N,8,1), connect to the LaunchPadTM and send commands to the Transmitter in real time.

    The 'boostxl_afe031_f28004x_dacmode' example uses GPIO28/29 for SCI. Make sure the F280049C LaunchPad's switch settings match the respective states documented in https://www.ti.com/lit/spruii7 Table 4. Alternate Function Switch Settings for 'SCIA to virtual COM port'.

    Best,

    Kevin
