IWR6843ISK: IWR6843 not getting recognized on the mmWave Demo Visualizer software.

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843, MMWAVEICBOOST, UNIFLASH,

Hi,

I am a new user of TI's IWR6843 mmWave sensor kit. I have a whole setup of IWR6843 + mmWAVEICBooster + DCA1000 data acquisition module setup connected to a 5 V source. The current consumed by this setup is close to 880 mA. The mmWAVEICBooster kit is connected to my Windows 7 laptop through the XDS110 microUSB port. I see there are two COM ports on my Device Manager list - XDS110 Class Application/User UART (CFG_port) and XDS110 Class Auxilliary Data Port (Data_port). 

My problem now is that, the mmWave Demo Visualizer web app is not able to recognize the board. I keep getting the "Hardware Not connected" message again and again. I opened the COM ports using Putty to verify my results. I came across this post on the Forum and as it says, is there an issue with the FTDI/XDS Drivers on Windows? Please, do let me know. I have attached the photo of the mmWAVEICBoost and my setup.

Thanks,

Vijay

    Hi Vijay,

    For running the Out of box demo with the mmWaveDemoVisualizer, please configure the MMWAVEICBOOST in stand-alone mode using the correct Jumper settings.

    1. Disconnect the DCA1000 EVM (the blue cable) as it is not needed to run the  SDK out of box demo.

    2. Configure the switches and SOP jumpers on the Carrier Board for standalone mode as shown in the quick start instructions on this page and follow the quick start instructions to run the SDK demo.

    MMWAVE SDK Demo - 68xx Lab User's Guide

    3. Make sure that you are using a 5V 3A power supply (The power supply be able to supply at least 3A).

    Regards

    Hi Nitin, Thanks for your immediate response, I appreciate it very much.

    I have configured the Mux on mmWaveICBoost for standalone mode. I have the jumper on SOP0 and removed the jumpers on SOP and SOP2. Still, the Demo Visualizer says "Hardware Not Connected". I flashed the demo .bin file using UniFlash as well. There is no improvement. The current, however, has dropped from 870 mA to 340 mA. Is it because I have disconnected the Data Acquisition Module? My current meter can source till 8 A.

    Hi Vijay,

    Are you configuring the COM ports in the mmWaveDemoVisualizer? You need to go to Options->Serial Port in the mmWaveDemoVisualizer and configure the Control and Data COM ports as shown below and press OK. This should change the status to Hardware Connected.

    Hi Nitin, I have been trying to do the same since yesterday to no avail. I looked through the mmWaveICBoost user guide on Page 14, table 3 and change the MUX Switches, it hasn't changed.

    I was running a web application of the demo visualizer and I thought it might be an issue with my firewall, so I downloaded a local application on my laptop, no improvement. It still says Hardware Not Connected!. 

    Is there a command line utility to the Uniflash tool so I can use it for my device. There are too many softwares, too many web applications - It'll be really helpful if you guys had a single consolidated page where I can find everything I need. I am running out of ideas, at this point.

    Vijay,

    As the COM ports are shown in Windows Device manager, the hardware seems to be OK. A couple of things to check:

    1. Do you see the EVM Com port listed in the above dialog box in demo visualizer i.e. under Options->Serial Ports. If you don't see the ports listed in the drop downs, it means that the required drivers are not installed.
    2. When you run the Visualizer for the first time, it asks you to install the CCS Cloud agent. The Cloud agent installs the necessary drivers required for the Visualizer to communicate using the COM ports. You need to install this. Please also try on another machine and install the Cloud Agent.
    3. Make sure that you are using the Chrome browser and not Internet Explorer.

    Nitin,

    I have tried all this and I have the extension installed. Only after I select the ports (Data_port and CFG_port) from the dropdown menu, I get the message "waiting for data" on the status bar. I have the TICloudAgent bridge installed.

    Vijay,

    If you are able to get "Waiting for Data" in the Visualizer status bar, that means that the EVM is connected and waiting for the Sensor configuration. What happens when you press the "SEND CONFIG TO MMWAVE DEVICE" button on the Configure Tab? What do you see in the console? Could you provide a snapshot of the console?

    Nitin, Thanks for your response. I couldn't get the demo visualizer working continuously as the connection is very finicky. I tried sending the mmWave configuration files to the EVM and I got the EVM working and was able to observe the range profiles of a square patch with a known RCS. I tried doing the same again today morning but now again it doesn't seem to work. Should I erase flash and reload a new set of configuration files? Do let me know..

    Thanks for your help,
    Vijay

    I also have this problem; just got the modules and we are unable to run demo it, the demo software is unable to connect hardware ports...i was hoping to connect with someone from TI support and maybe get an exchange or send it back to see if there could be something wrong with it.
    any help to get it going much appreciated, its quite alot of money for me. thanks

    Vijay,

    Please press the NRST switch on MMWAVEICBOOST after connecting power and see if you are able to run the demo every time after that.

    Nitin, It doesn't work. I have tried the RESET button a lot of times. It is proving to be a very difficult problem. The mmWave studio doesn't connect to my device using SPI, the demo visualizer is very finicky. 

    I am trying to debug, and do you guys have a data where the current consumption is mapped for the different modes? I know have the current at 850 mA, is that okay? Is the board really consuming 4 W of power?

    I have attached the photo of my setup again.

    Hi Nitin,

    Any updates on this? Is there a solution ? Can you tell me how to erase flash on the device using Uniflash? I search for Erase on the uniflash utility, I dont get anything on the results?

    Hi Vijay,

    I would suggest de-coupling the two issues i.e. looking at  the mmWave Demo Visuaizer connection issue in isolation to the mmWave Studio / SPI connection that you've been discussing over a separate thread. I would focus here on the mmWave Demo Visualizer issue.

    You indicated earlier on this thread that you are able to get the EVM to connect with the demo visualizer and get the demo running sometimes but it's not always reproducible and so we are not sure whether this is a Demo Visualizer problem or related to the mmw demo running on the EVM.

    In order to find this, could you try to run one of the other 68xx labs available in mmWave Industrial Toolbox such as People Counting, Area Scanner etc. These labs use their own visualizer. The easiest one to try would be the Area Scanner Lab. Please follow the instructions in the Quick Start section to flash the pre-compiled binaries and run the lab with the provided Matlab based visualizer.

    Regards

    -Nitin

    Hello, Nitin,

    I am having somewhat similar issues. I successfully flashed the demo binary for the IWR6843 stand-alone using UniFlash. I was having a similar issue with Demo Visualizer after configuring the COM ports via the Serial Tab and had the same "waiting for data" scenario. I went to Help->About to ensure that the SDK matches the 3.0 or 3.1 options available in the Setup Details section, but the SDK is not listed. I was reading through these Q/As and saw this last message recommending pressing the NRST switch. This immediately changed the "waiting for data" to "Hardware Connected". But I am still unable to get anything in the Console Messages after pressing the "Send Config to MMWave Device" button. The SW that I loaded provides a directory of mmwave_sdk_03_01_01_02. I used the 339K bin dated 1/17/2019 in the demo/xwr68xx/mmw folder and moved SOP back to open after the successful flash load. I have tried both SDK Version 3.0 and 3.1 to no avail. I have been using the 4Rx, 2Tx (15 deg) option and have left everything else at default. I'm hoping you might have some more ideas, here, and please let me know if you need additional information from me.

    Thank you very much,
    Jeritt

    Hello,

    Please run the MMWAVE SDK Demo - 68xx shown in the below link just with IWR6843ISK and MMWAVEICBOOST boards alone without connecting the DCA1000 board.

    http://dev.ti.com/tirex/#/?link=Software%2FmmWave%20Sensors%2FIndustrial%20Toolbox%2FLabs%2FmmWave%20SDK%20Demo%2F68xx%20-%20mmWave%20SDK%20Demo 

    Also post the console messages for any possible error.

    Also review if there is any "NERR" LED (Error LED) is illuminated, if yes, then you may have re-cycle the power and issue a NRESET operation. 

    Thanks and regards,

    CHETHAN KUMAR Y.B.
