IWR6843ISK: Device not found

Helen Koujak

Part Number: IWR6843ISK
Other Parts Discussed in Thread: DCA1000EVM, , UNIFLASH, MMWAVEICBOOST

Good Afternoon,

I am currently using IWR6843ISK ,DCA1000EVM . The problem I am encountering is that I have a Matlab script witch is supposed to run the Radar but I got error message that the device is not found. After inspecting the device manager and the ports.it is right there COM3 for UART and COM4 for data .I also installed the Texas Toolbox to read data from the radar board and followed all the instructions about switches but also this flashing failed.

Can you please provide more information for fixing the issue or connect me with someone in Germany who can support.

Thanks in Advanced

Greetings

Hello,

Before touching low level raw data processing, are you able to flash an example binary such as the Out of Box demo from the Toolbox using Uniflash? And then send it a config using functional mode?

Hi,

This is what I got ( "Image loading failed: Not able to connect to serial port. Recheck COM port selected and/or permissions") eventhough I changed the switches as the instructions (on off on on off off).

Can you also provide me with some source(pdf or videos) to see what commands are sent through the port?

Best Regards

Helen

Hello Helen,

This is a bit atypical. Could you take a picture of the EVM while it is plugged into your computer? Is there a program or script running such as TeraTerm that is holding the COM port hostage? Perhaps you could try a different USB cable if you have not already.

Best Regards,

Hi,

TI mmWave studio 02.01.01.00 functions correctly as it successfully detects the ports and records data. However, I encounter this issue when attempting to run the radar using a MATLAB script. Unfortunately, the radar device is not detected, that is why i need some additional resources on the commands sent to the port. Although I've utilized a serial port monitor program to gather information, I'm puzzled as to why I receive no response when sending the same commands. It seems that the port only reads, and despite being able to write to it, I am unable to detect the device.

I am not using this program TeraTerm and the cable is fine . I attached images of the radar in the flash mode

Hello,

So you are saying that using mmWaveStudio you are able to fully go through the raw data capture process, but not using this MATLAB script. Is this a custom MATLAB script? We have example MATLAB script examples you can use as reference within mmWaveStudio's installation directory.

Also, when you were trying to flash the sensor using UniFlash, were you using just the 6843 or 6843 + MMWAVEICBOOST? Your ICBOOST switches are in DCA1000 capture mode, and are incorrect for flashing and functional mode. Guide on switches for non DCA1000 related activities can be found on https://dev.ti.com/tirex/explore/node?a=1AslXXD__1.30.01.03&node=A__ACzleIuZ4g1GuBmtlq-cGg__radar_toolbox__1AslXXD__1.30.01.03&placeholder=true.

Again I wanted you to attempt to flash with UniFlash to confirm that the sensor can still be flashed and whether or not there is anything fundamentally wrong with the communication to the COM port.

Best Regards,

Pedrhom

Actually this flashing using Uniflash did not work but i was able to record some data and postProc them. Any way thank you for your help this solved my error. ICBOOST swiches were incorrect. now the device is recognized and connected .
