    Hello Vinayak,
    The SDK has a "Capture demo" application that provides an example of copying the ADC data to the DSP L3 memory. This can then be read using CCS. The SDK user guide (software-dl.ti.com/.../mmwave_sdk_user_guide.pdf) provides the details about using this demo. See section 3.4.3 which specific to running capture demo on AWR1642 device.

    Please note that this version of the demo application enables copying ADC data of single RX chain.

    Hi Vivek,
    The information you provided was useful, but thing is, I imported the demo project into CCS and did all steps according to User's guide of mmWave SDK. But when I give give build to it, it shows nothing on the console window, and in debug mode I ran it according to steps, but I'm getting some files are missing, like e.g, boot.c etc.
    I can run it continuously, and I'm not getting any ADC data in memory location.
    So please help me with it.

    Hello Vinayak,

    If you want to debug Capture demo with CCS then here the steps you need to follow (mostly same as user guide)

    • Create CCXML file as given in section 4.3.3.1 (you may have done this already)
    • Launch and connect to both cores. section 4.3.3.2
    • Download 'xwr16xx_capture_demo_dss.xe674' to C674x and 'xwr16xx_capture_demo_mss.xer4f' to Cortex_R4. These debug images are built by the makefile given in mmWave-SDK Capture demo.
    • Resume execution of both cores.
    • Connect UART COM port as mentioned in section 3.4.3 and proceed with commands.

    Note-  Flash ccsDebug image to the device as given in section 3.3.2 before starting with above-said steps.

    mmWave-SDK has the makefile framework to build the demo applications. Even though you can create CCS project for demo at your end.  Follow this e2e post to create CCS project for mmWave device.

    Hello Jitendra,
    Thanks for the information.
    I have done all the steps you mentioned, except UART COM port commands, I'm not getting how to open CLI window to connect UART COM .
    Please give inputs to it.
    Thanks,
    Vinayak

    Hello Jitendra,
    I have one doubt, to capture ADC data, AWR1642BOOST EVM is alone sufficient or do I also need MMWAVE-DEVPACK or LAUNCHPAD with it?
    Please reply asap.
    Thanks

    Hello Vinayak,
    In the standalone AWR1642 EVM you can capture 640KB of data and store it in the internal L3 memory. If this is sufficient then you dont need external board.
    If you need a larger capture size you would have to use an external capture card that would take the ADC data over LVDS. An example of this is the TSW1400 capture card (www.ti.com/.../tsw1400evm). To interface to this board you would need the MMWAVE-DEVPACK as well .
