TIDA-01570: How to collect raw data of TIDA-01570 using DCA1000?

Part Number: TIDA-01570
Other Parts Discussed in Thread: AWR1642BOOST, UNIFLASH, DCA1000EVM


I want to collect raw data of TIDA-01570  using DCA1000. 

I have connected the LVDS interface and serial port (The TX and RX pin on the J4).

SOP0 and SOP1 has been set to 1, SOP2 has been set to 0 .

Other operations are exactly the same as using AWR1642BOOST.

But when I connect RS232 in mmWaveStudio, the following error occurs:

[10:03:09]  [RadarAPI]: Error: Connection failed: Calling_ConnectTarget returned 3

It seems that the serial connection failed, but I have already connected the configuration serial port (The TX and RX pin on the J4).

Do I need to connect the data serial port as well? I noticed that the data serial port (same pins as AWR1642BOOST) is connected to the CAN transceiver.

Thank you


  • Hi eehzux,

    RS232 is the same UART which is being used for flashing binary to the device using UniFlash.

    Let's first check if you are able to flash the binary to the device using these UART lines. Please refer document (section 3.1) to flash the binary to the board over UART.

    And on this board SOP_2 is controlled via J3 jumper whereas SOP_1 and SOP_0 are controlled by the resistors.

    Table 3 of this document shows the SOP setting for all the mode of the device (flashing/debug/functional).

    Ideally this board is meant for functional and flashing not for debug mode, so can't connect mmWave Studio directly to this board.

    Other option to use mmw demo which provides an option to stream raw ADC data over LVDS which you can capture using DCA1000EVM.

    Please refer mmwave_sdk_user_guide.pdf (section 3.3.2) from mmWave SDK 3.3 for this purpose. 

    Note- DCA1000EVM_CLI_Control.exe is available in mmwave Studio installation.



  • Hi Jitendra,

    Thank you for your patience.I have found a solution.

    1. Need to connect TIDA to DCA1000 through the third COM port of AR-DevPack-EVM-012;

        The serial ports AWR_RS232_RX and AWR_RS232_TX for configuring the radar are not only connected to the header but also to the high-speed interface QSH-030-01-L-D-A. That is to say, when using the pin on the pin header to connect, the serial port may be connected to the capture card through the high-speed interface at the same time, and the serial port of the other end of the capture card is at the default level. success. When the serial port on the pin header is disconnected (unplugged) and the third COM port of the AR-DevPack-EVM-012 of the capture card is connected, the connection is successful, which verifies this conclusion.

    2. Unsuccessful when connecting SPI directly in mmWaveStudio. The resistors R76, R77, R79, and R82 need to be removed.

        Cause: AWR_SPIA_SCLK, AWR_SPIA_MOSI, AWR_SPIA_MISO, and AWR_SPIA_nCS are connected to the high-speed interface QSH-030-01-L-D-A and the CAN transceiver TCAN4550RGYRQ1 at the same time. The connection at the CAN transceiver side needs to be disconnected.



  • Hi eehzux,

    Glad you are able to resolve the issue and thanks for posting the solution here for other forum members.
