RTOS/IWR6843ISK: Getting the ROS Texas module to work with FTDI

Part Number: IWR6843ISK

Tool/software: TI-RTOS

Hi, 

I am currently using the MMWAVEBOOST board + IWR6843ISK under ROS (followed your guide). 

 I wonder if it is possible to get the same configuration, but with the mmwaveboost's ftdi instead of the xds110?

I tried to check possible paths of the UART through the mux, and it seems like it is possible to me. In practice, it did not work, and I'm starting to doubt that it is possible, as the XDS creates two ports /dev/ttyACM0 and /dev/ttyACM1 (Can I know how, by the way?)

Regards

    Hi,

    The XDS110 shows 2 COM ports
    1. User / config port - UART RX/TX
    2. Data port - BSS Logger

    The BSS logger is not routed to the FTDI. Unless modification is made in SW to route the data via SPI or other ports on the FTDI, the data will not be available to the FTDI

    Regards,

    Dear Charles, 

    First of all thanks for your answer. 

    I still have several questions 

    - What do you mean by "SW" ? 

    - I read the schematic, and what i find routed to the XDS110 is: JTAG, USB, UART, I2C, and part of sthing with "BSS and MSS" (CLK and CS) ; which one of these ports is the BSS one? 

    I thought of switching J14 and J15, with no success 

    Is it possible to have a mux configuration, even with extra wire, to use the FTDI instead of XDS110 in that case? 

    If not, is it thinkable, in a custom pcb design to include the XDS110 hardware part and to flash the binary (found it in ccs/ccs_base/common/uscif/xds110)? 

    Thanks a lot

    RADAR_MSS_LOGGER_SPIB_CLK  - MSS logger

    RADAR_BSS_LOGGER_SPIB_CS - BSS Logger

    This should be possible, You will need to confirm if the FTDI driver supports it.

    Yes, The XDS110 driver, firmware and update procedure is available online
