DRV8301-HC-C2-KIT: GUI not connecting

Part Number: DRV8301-HC-C2-KIT

I have followed the directions in the QSG (quick start guide). All the appropriate LEDs seem to light up correctly. LD1 green, LD3 slowly blinking red.

SW3: OFF (UP) position
SW2: Position 1 = ON (UP), Position 2 = ON (UP)

The USB driver installed automatically. When I run the GUI that's included on the flash drive, it won't connect. I can't seem to find that there is a specific COM port for setting it up manually. Don't know if that's a Windows 10 thing.

Any help in figuring this out would be appreciated.

  • I'm guessing this is the InstaSPIN BLDC GUI? I'm not sure what version of it is provided on the flash drive. There's also a version in controlSUITE (under \development_kits\DRV830x-HC-C2-KIT_v105\) that may be newer. Have you tried that one?

    Thanks for the suggestion.

    InstaSPIN-BLDC_GUI_DRV83xx_v104.exe looks to be the same version in both locations (flash drive and in controlSUITE location.)

    Tried the one in controlSUITE with the same results.

    Connecting the USB cable makes the sound as if it's connected and I can see it in Devices as Texas Instruments XDS100+R232 V1.0. The GUI is not recognizing that it's there. The instructions say that you can set it up manually by telling it which COM port it is set up as, but I am unable to get it from the device. If I click on it, it only gives me an option to remove it.

    Have you loaded the .out into your device? Can you see the COM port in the device manager?

    I was under the assumption that the .out was already preloaded. I'm new to how this works. I'm not sure how to load the .out. Help in that regard would be helpful.

    I had to unhide hidden devices to see the COM port. Looks like it's COM9.

  • In reply to Scott Pugh:

    I'm assuming the .out file that I would load is InstaSPIN-BLDC_GUI_DRV8301_v104.out. I haven't been able to find how to load it.
    Also, I tried changing the port by hand to COM9 and it changes back to COM1.

    The documentation does make it sound like the device should be pre-flashed with the application, but reload it just in case. Yes, the .out you mentioned should be the right one. You can load it with Code Composer Studio--are you familiar with CCS yet? The Code Composer YouTube channel has some nice training videos.

    You can load the .out by using the Target Configuration view to make a new Target Configuration for your board, right clicking on it and selecting "Launch", connecting to the CPU (click on the CPU and select "Connect Target"), and Load Program for the .out you're using.

    I'll look into what might cause the COM port to reset. You should also make sure that the switch settings on your controlCARD match those described in the quick start guide.

    In doing some checking, it looks like the driver is not installing correctly. I have Windows 10, 64 bit machine. Tried uninstalling and reinstalling and still getting an error. "Windows found drivers for your device but encountered an error while attempting to install them."

    The documentation says to: Do not let Microsoft search for the driver, instead browse to the following location on the USB stick shipped with the kit <Drive Name:\Drivers>,\

    there is not a 'drivers' folder on the USB stick (flash drive).

    I've tried finding the appropriate Windows driver on the ti web site with no avail.

    Please help?

  • In reply to Scott Pugh:

    Thanks for your patience. Were you able to reload the application? If you don't want to deal with CCS just yet, we also have an online UniFlash tool (http://dev.ti.com/) that can load the .out for you.

    I don't know what driver that document is referring to either. As long as you're able to connect to the device using an XDS100 and the COM port is showing up in your device manager, you shouldn't need to install anything else.\

    Can you show me a screenshot of what you're seeing in the connection wizard?

    Whitney
  • In reply to Whitney Dewey:

    The UniFlash tool can't find the port either. I'm not sure why the USB port is not finding and/or installing the Windows driver. The first screen shot shows 3 Texas Instruments USB ports, the COM7 device is the one that goes with a LAUNCHXL device that I have and it works correctly. The COM9 device, I have now idea what it is associated with. The device with the error is the one associated with the device I'm trying to get up and running.

    I removed both the COM9 device and the errored device and reattached the CRV8301-HC-C2-KIT USB, the results are shown in the second screen shot.
