Hi,
We are evaluating IW1843 3D Traffic Monitoring demo and we found out it always crashes after running for some time (half an hour to two hours). Powerdown recovers it.
We used the demo in mmwave_industrial_toolbox_4_2_0.
Do you have any idea about what causes the crashes?
Thanks
I would like to add.
We are also encountering a more serious issue wherein the sensor doesn't start after successfully sending the CFG file. The sensorStart command seems like breaks the USB connection and will reconnect. And then the matlab GUI will crash after this. Even if we power down the device multiple times, it cannot for a while. Note that we are using the TI default config and demo.
Is it somehow related to hardware?
Hello Mary,
Can you provide the log txt file from a time when it crashed after 30 min?
Can you also provide the log txt frile from thwen the sensor doesn't start after sending the cfg file?
In the case of not starting after sending the cfg file:

Hello,
I'm using the pre-compiled GUI.
Attached is the log file when it crashed after running for some time.
We've also noticed that crash will occur when initially we have the demo running with the device facing up, and when we move it try to move the device to face sideways and the gui will hang up. The log file doesn't log this error though. It will just completely stop. This is repatable.
I also tried not running the GUI and just stream the data output in realterm. When we move the device, the data streamout in realterm will stop. So I guess, it's the firmware that crashes.For the USB issue, I will get back to you.

I managed to find the line of code (CCS project) where the device hangs up when it is moved.
It's the lines:
objectdetection.c
1986: DPC_Objdet_Assert(objDetObj->dpmHandle, (objDetObj->interSubFrameProcToken == 0));
and
objdetrangehwa.c
646: DPC_Objdet_Assert(objDetObj->dpmHandle, (objDetObj->interSubFrameProcToken == 0));
To quickly check, I tried to skip these assert lines by modifying objectdetectioninternal.h into:
#define DPC_Objdet_Assert(handle, expression)
//#define DPC_Objdet_Assert(handle, expression) { \
// _DPC_Objdet_Assert(handle, expression, \
// __FILE__, __LINE__); \
// DebugP_assert(expression); \
// }
Somehow, it still looks like the demo works even though I move the device and the crash will not occur. I haven't tested the long time run yet (the other issue that I mentioned).
However, I'm not sure if this is a deployable solution or how skipping this line affects other functionalities.
Please help.
The issue causing the crash was when you're moving the sensor yourself there are too many points being generated because to the sensor it appears the entire scene is moving. When there are too many points you may run out of time to complete the processing and output by UART before the chirping and processing begins for the next frame.
You've removed the check that the processing has completed before beginning the next frame.
I would recommend instead that you issue a sensorStop before moving the sensor so that this error doesn't occur or increase the available time by increasing the frame period or reducing the maximum number of detected points.

Thanks for your suggestions. I will try that.
In limiting the number of points, I want to confirm that you are referring to this line in the config file:
trackingCfg 1 2 1000 20 67 105 50
How is the device selecting the X number of points to process in a given scene with a lot more points than the limit? By distance, snr, etc?
Hello,
In objectdetection.c you will find:
/*! Maximum Number of objects that can be detected in a frame */
#define DPC_OBJDET_MAX_NUM_OBJECTS 500U
which needs to be reduced. This changes the size allocation of the CFAR buffer so that after the max is reached new points aren't detected. Thus it follows the CFAR processing order for priority, along doppler then along range.
