IWR6843AOPEVM: Unable to connect to UART data port using Vital Signs firmware

Hi

From device perspective there, there is no difference in booting out of box demo or vital signs. If the OOB is running on the device then I do not see any reason why Vital signs would not work. However, configurations will be different for both of them. But at least I do not see any issue in connection.

Can you also try to run 3D people tracking demo and see if you are able to connect?

Regards

The actual port connection works as I can see data in Industrial Visualizer, however, I can not retrieve it from the UART.   

I am able to Flash the 3D_people_track_6843_demo.bin successfully. 

I then unplugged the board, switched the S3 off, and moved
SOP2: S2.1 OFF, S2.2 ON, S2,3 On , S2.4 OFF
SOP1: S1.1 OFF, S1.2 ON, S1,3 OFF , S2.4 OFF

follow these configuration instructions: move file:///Users/ona/Documents/radar_toolbox_3_20_00_04/source/ti/examples/Industrial_and_Personal_Electronics/People_Tracking/3D_People_Tracking/docs/3d_people_tracking_user_guide.html 

USING the 3D People Tracker Code and Config:

Using a Python script:

I load the config 'AOP_6m_default`, found in the RadarToolbox, onto the board.

I run the code, and no data from the UART:

OUTPUT:

echo sensorStart
Done Debug: Init Calibration Status = 0xffe
Error -1

Vital Signs with People Detection

Using the same Python script as above:

I load the config 'vital_signs_AOP_6m`, found in the RadarToolbox, onto the board.

I run the same code as above, and no data from the UART:

I am able to get data for the out of box demo, but not for 3D_people_track_6843_demo or for the Vital_Signs demo.

Using the code from the Visualizer: 

`ERROR: No data detected on COM Port, read timed out
Be sure that the device is in the proper mode, and that the cfg you are sending is valid
ERROR: No data detected on COM Port, read timed out
Be sure that the device is in the proper mode, and that the cfg you are sending is valid

Hi

It seems it is not a demo issue but some connection problem. Did you run the Out of box demo using the Industrial visualizer?

Is it possible to isolate if the problem exists with cfg port or data port? Do you see any prompt on the cfg port when you send the cfg?
