IWR6843ISK: Frame configuration error on 3D People Counting demo

Hi,

I have compiled the 3D people counting demo from source but I cannot get it to run under the debugger. It fails every time on the call to MMWave_config() and prints the following message:

Error: mmWave Config failed [Error code: -3110 Subsystem: 75]

I am trying to run it standalone without the GUI app, so I did modify it to read configuration parameters from a text string instead of via the UART. I am using the settings from the file

ISK_6m_default.cfg

Configuration proceeds with no errors, the problem occurs during the “sensorStart” command. I have used the debugger to trace it to the MMWave_config() function as I mentioned before.

Here are the versions of everything:

MMWave SDK v3.5.0

Industrial toolbox v4.10.0

Ubuntu 20.04

CC Studio v11.1.0.00011

IWR6843ISK board rev D debugged via MMWAVEICBOOST

Do you have any advice on what might be going wrong?
