IWR1642: control via USB-UART adaptor

IWR1642: UART without TM4C1294NCPDT

Part Number: IWR1642
Other Parts Discussed in Thread: TM4C1294NCPDT, , , UNIFLASH

Hello,

I want to control IWR1642 without TM4C1294NCPDT using USB-UART adapter.

so, I referenced the IWR1642 datasheet and the IWR1642BOOST schematic, but I'm confused where the UART line is.

I guess AR_RS232RX(N4) and AR_RS232TX(N5) are Application/User COM port and AR_MSS_LOGGER is Data COM port(only transmit). Is my guess correct?

If yes, can I get data from IWR1642 by connecting this line directly to the USB to UART adapter?

Thanks and regards.

    Hello JINHYEONG LEE,

        Your understanding is correct, i.e. AR_RS232RX(N4) and AR_RS232TX(N5) are Application/User COM port and AR_MSS_LOGGER is Data COM port(only transmit)

    Yes, you can  get data from IWR1642 by connecting this line directly to the USB to UART adapter as shown below.

    Care must be taken some of the USB to UART may not reproduce escape character, then Uniflash tool may not understand properly. 

        

    Thanks and regards,

    Thank you for reply

    Referring to the origin question, I'll use FTDI based USB to UART converter.

    Can I get the source code of TM4C1294NCPDT for reference?

    Hello,

        Unfortunately, TM4C1294NCPDT code used as XDS110 emulator is closed, only binary is available to use. 

    Thanks and regards,
