IWR1642: mmWave Demo Visualizer customization to get the data from XDS110 debug probe

Part Number: IWR1642


Hello,

As I discussed in the following thread,

e2e.ti.com/.../2582024

Visualizer would need to be customized to get the data from XDS110 debug probe. Could you please describe what customization is required? Is the customization possible by a user who are not TI engineer?

The target device is IWR1642, the circuitry is modified from IWR1642BOOST. Pin assignment of XDS110 debug probe is clarified in the thread.

Best Regards,
Katsuhiro

  • Hi Katsuhiro,

    On the EVM, TM4C is a on-board XDS110 emulator.

    If you don't want to put a XDS110 on your board, you can use external USB<->UART cable to connect your board and PC.

    For mmwave demo, 2 UART is required for data and configuration transmit.

    Application/User Uart: Configuration port 115200bps: UART_RX/TX port <-> USB-UART cable <-> PC

    Auxilliary Data Port: Data port 921600bps: MSS_LOGGER-> USB-UART cable -> PC

    To process this data: See the Visualizer User's Guide, section 4.4, to understand what the data contains. Information on the actual data is available in the doxygen - <mmWave_SDK_Install_DIR>\packages\ti\demo\xwr16xx\mmw\docs\doxygen\html\index.html.

    User's Guide: www.ti.com/.../swru529a.pdf

    Also, you can use the ti online GUI compose to customized your own GUI. Link:

  • Hi Wesley,

    XDS110 debug probe will be used to communicate with IWR1642.
    ⇒ PC<->XDS110 debug probe<->IWR1642 on the customer's board

    These pins/signals on three connectors of XDS110 debug probe is to be used to communicate with IWR1642 on the customer's board.
    2.3 CTI-20
    supports
    1 - TMS
    2(15) - NTRST or nRESET
    3 - TDI
    7 - TDO
    8 - GND
    11 - TCK
    13 - GPIOOUT0 - if SOP2 is pulled up over XDS110 interface
    17 - GPIOIN0 - PMICGOOD or POWER GOOD (optional)

    2.4 Aux - 14pin
    5 - GND
    12 - UARTTx (connected to N4 - RS232_RX (AR_RS232RX) of IWR1642)
    14 - UARTRx (connected to N5 - RS232_TX (AR_RS232TX) of IWR1642)

    2.5 Probe Expansion Header
    9 - GND
    17 - UART7 Rx (this is connected to MSS_Logger_TxUart

    To use mmWave Demo Visualizer:

    Could you please describe what modification is required exactly?

  • Hi Katsuhiro,

    For SDK demo execution, 2 UART is required for data and configuration transmit.

    Application/User Uart: Configuration port 115200bps: UART_RX/TX port <-> USB-UART cable <-> PC

    Auxilliary Data Port: Data port 921600bps: MSS_LOGGER-> USB-UART cable -> PC

    For CCS DEBUG, JTAG(TDI, TDO, TCK and TMS) should be used to load program though CCS.

    If you have any other questions, please let me know. Thanks.

    Regards,

    Wesley

  • Hi Wesley,

    Two UART and JTAG you mentioned is to be connected via XDS110 debug probe. That has already been discussed in the thread.

    What I am asking is what modification would be required to mmWave Demo Visualizer. If it is required, how?

    Best Regards,
    Katsuhiro
  • Hi Katsuhiro,

    If you the online visualizer can meet your requirement, you can use it directly. You don't need to do any change on Visualizer.

    Select the right UART COM port, then run the demo.

    Regards,

    Wesley

  • Hi Wesley,

    Understood. It's been clear.
    Thanks a lot!
