IWR6843AOPEVM: 3D People Counting Lab stops working

Hi,

Can you use TeraTerm to send the .cfg file to debug? It should give an error message. Additionally, you could start with a working config file and make incremental changes to understand what breaks it. Let us know how that goes and what more info you can get.

Best,

Nate

Hi Nathan,

Thanks for the response. 

The built in cfg for 3D People Counting is working perfectly using tera term. But when I am making changes only to the profilecfg and framecfg parameters with the values from mmwave estimator to improve the range I am getting an error message '-1' when I am starting the sensor. 

Default config:

profileCfg 0 60.75 30.00 25.00 59.10 394758 0 54.71 1 96 2950.00 2 1 36

frameCfg 0 2  96  0 55.00 1 0

Improved config from estimator:

profileCfg 0 60 2 4 20.95 0 0 13.76 1 128 8027 0 0 30

frameCfg 0 2 66 0 40 1 0

Could you help me with the issue please?

Hi Jomin,

Can you make the changes one at a time so we can see which parameter breaks this?

You can also find the acceptable values and limits for the parameters here in the user guide PDF

Hi Nathan,

But these values in profileCfg and frameCfg are inter-depended. So will it be a good idea to change one at a time?

Thanks,

Jomin

HI Jomin,

Some of the values are interdependent, but others may be changed sequentially. You can also put the device in debug mode to see more detailed output.

I have found that the below configuration works. I would be willing to bet you're not allocating enough ramp end time. Put it in debug mode to get the exact error message.
