IWR6843ISK: IWR6843ISK connection issue

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST

Hello,

I am evaluating an IWR6843ISK ES2.0 EVM on a laptop running Windows 10 and Ubuntu 20.04 in dual boot mode. I did not install any drivers, but I could see the serial ports (COM) immediately after connecting the standalone board using the USB cable. The demo worked fine.

But since today I can not see the serial ports any more after connecting on both operating systems.

I installed the "CP210x USB to UART Bridge VCP Drivers" on Windows but nothing changed. Also, I tried to set back all Windows USB drivers, but it did not help.

On Windows I use the Device Manager to check the COM ports. On Ubuntu I use the command "ll /dev/serial/by-id".

What else can I do?

Hello

Is it possible for you to try the steps using a different windows only pc.

Wanted to make sure the EVM is functional before we get to the specific debug.

Hello,

I just tried connecting the sensor to 3 different Windows-only PCs and I could see the COM ports only on one of them. I also used different USB cables, but nothing changed. So maybe the device has some kind of the defect, but all 3 LEDs seem to work correctly after connecting.

Hi,

you send you could see the COM ports on one of the PCs, did it EVM work fine on that PC? If you have the MMWAVEICBOOST can you confirm the EVM works fine in that mode?

Hi,

the PC which showed the COM ports is not available right now. But I could test the EVM mounted on the MMWAVEICBOOST and it works. I can see the point clouds.

In standalone mode there are still no ports. Even after I switched the pins in to the right position.

Hi,

if its showing the COM ports and working on another PC, then its a PC issue.

I would uninstall the drivers and reinstall it
