AWR2944EVM: DCA1000 + AWR2944EVM

Part Number: AWR2944EVM
Other Parts Discussed in Thread: DCA1000EVM, AWR2944

Tool/software:

Hello TI Team,

I was working with AWR2944EVM with the DCA1000. I was following the DCA1000 training video and the associated pdf. 

But, whenever I am connecting one micro-USB to the RADAR_FTDI port on DCA board, the FTDI ports do not appear in my device manager. However, when I am connecting the micro-USB to the FTDI port of the AWR board, the FTDI ports do appear in the device manager. Although it seems to be a temporary solution, I am getting "Connection failed: Calling_ConnectTarget returned 3" error in the mmWave studio output (picures attached). Also, the "RS232 Connectivity Status" remains disconnected in the RADAR_API (pictures attached). Can you please help me in solving the issue?

    Hello,

    With AWR2944EVM the USB should be connected to the FTDI port on the AWR2944EVM only. You should not be connecting USB to any ports on the DCA1000EVM with AWR2944EVM. This is described in section 2.9 of the AWR2944EVM user guide.

    Also, with AWR2944EVM the RS232 connection should be made with the highest number FTDI port. For example, if you see four ports instantiated like below, you need to select COM109 for the RS232 connection.

    Thank you, Adrian!

    I followed the steps you mentioned. Now, the only micro-USB is connected to the FTDI port of AWR2944EVM, as in the following figure

    This time, the XDS ports disappeared from the device manager. However, according to your suggestion, I did choose the highest number FTDI port for the RS232 connection

    However, the "RS232 Connectivity Status" still remains disconnected


    with the same output error

    Can you please take a closer look to see if you can help me with some additional suggestion(s)?

    Best Regards,

    Sabbir

    Hello,

    Can you confirm if you followed the requirement to power on the board before you plug in the USB?

    Hello,

    Thank you! This is something I didn’t know. However, it seems to be working perfectly now. I’m not quite sure what the issue was. I did press the reset button once or twice and then tried again with your suggested sequence. If I remember correctly, most of the time I was plugging in the USBs before powering up the board. I did try the opposite as well, though. I’m still not sure what the exact issue was, but I’m glad it worked.

    Once again, thank you for your guidance!

    Best regards,
    Sabbir

    Hello,

    Thank you for pointing that out. It worked. However, I was facing some issues with the FPGA on the DCA1000 board. It seems like, the green FPGA_DONE_LED on the DCA1000 board is not lighting up. I tried to flash the FPGA image, but couldn't do it. Since, connecting USB to the FPGA_JTAG (J4), the two new com ports (as indicated in the FPGA programming section of the DCA1000EVM Data Capture Card user's guide) do not appear in my device manager. Although the FTDI drivers are already installed in my system. For the same reason, the Diamond Programmer can't detect it.

     

    I think, for the same reason, during the DCA1000 set up stage in mmwave studio software, the FPGA version never appears.

    In addition, I was following the DCA1000 training video #4 by TI, but in my case, the GUI never lets me set the clock configuration and LVDS lane configuration, which is different from the case in the video.

    Can you please help me in solving these issues?

    Hello,

    For AWR2944 the clock rate is fixed so it is expected that you will not be able to configure the clock.

    When you power on the DCA1000 do you see any LED illuminated?

    Hello,

    Thank you for the clarification. Upon powering on the DCA1000, it is just the 5V LED that is turned on, nothing else.

    Regards,
