IWR6843ISK: "Not able to connect to serial port. Recheck the COM port selected."

Hello,

I will need some more information. Can you please ensure that you have set the SOP switches correctly as in this page: https://dev.ti.com/tirex/explore/content/mmwave_industrial_toolbox_4_7_0/labs/common/docs/hardware_setup/hw_setup_isk_ods_modular_mode_flashing.html

Are you connecting to the correct USB ports as described in this page: https://dev.ti.com/tirex/explore/content/mmwave_industrial_toolbox_4_7_0/labs/common/docs/software_setup/using_uniflash_with_mmwave.html

Hello Sabeeh,

Yes, the SOP switches are:

S1.1 - ON
S1.2 - OFF
S1.3 - ON
S1.4 - ON
S1.5 - OFF
S1.6 - N/A

The USB ports are identified by the OS. I had done the operation before, following the same procedure, and it worked.

Is it normal for the D7 led to be like this?

Thanks in advance! Best regards,

In flashing mode, it is normal for the LED to be in this state.

Sabeeh,

Note that the LED (D7) doesn't have the intensity of the others. It has a very low intensity!

Hey Guilherme,

I am aware and I can confirm this is not a problem.

So... If it is not a problem, do you have any idea why I can't communicate with the sensor?

Have you installed the correct drivers? https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

Yes I did! As I mentioned, I had never had any problems with communication before.

Have you tried doing a full power off/on of both the PC and sensor?

If there is an image currently flashed on to the device, are you able to get that working? In other words, put the device back into functional mode and test the application already on the device. This will atleast determine that there is nothing wrong with the hardware.

I already made all the suggestions you presented before asking the question here. The firmware on the board is not working. The sensor doesn't respond
