IWR6843ISK: mmwaveSDK Installation complete in Linux, but driver not recognized properly (Ubuntu 18.04)

Part Number: IWR6843ISK
Other Parts Discussed in Thread: UNIFLASH

Dear All,

I am able to work with my IWR6843ISK board in Windows and its working fine. Now, I wanted to use the IWR6843ISK board with Ubuntu 18.04. For this, I followed the below steps from document for SDK installation - dr-download.ti.com/.../mmwave_sdk_release_notes.pdf

Although GUI did not show up for me, I was able to follow the similar steps in command line and complete the installation. 

I also installed UniFlash, and TI cloud agent. After all this, In Demo Visualizer when I mention the CFG and Data Port, an Error comes up showing "Hardware not Detected" 

When I tried the below command, I am able to see the Cp2105 is detected. 

Is this the expected output or should device be recognized with Texas Instruments ID. I am suspecting this might be the reason for Demo Visualizer not detecting my Hardware. 

What can I do to get the device detected properly ? Is there any other document link with these details ?

    Hi,

    Many of our mmWave Radar devices utilize a Silicon Labs UART-USB bridge, which you likely still need to install drivers for. The latest drivers should be available here:

    Hi Alec,

    I already installed that. And I get to detect the Silicon Labs ID in my USB list. Image attached below.

    But the problem is I am not able to detect it as /dev/ttyACM0. I think that's what UniFlash software expects.

    I am expecting the serial usb list should show something like below image.

    How to get it detected as /dev/ttyACM ?

    Hi, 

    The serial ports are typically only detected as /dev/ttyACM0 and /dev/ttyACM1 when using the MMWAVE-ICBOOST carrier board. /dev/ttyUSB0 and /dev/ttyUSB1 are expected when connecting the device to the PC in standalone mode. It seems this is what is shown for your setup.

    Are you able to flash using Uniflash and run the demo visualizer using /dev/ttyUSB0 and /dev/ttyUSB1 for the serial ports? Note, /dev/ttyUSB0 is typically the CFG port and  /dev/ttyUSB1 is typically the DATA port. 

    Best Regards,
