IWR6843AOPEVM: About CFAR-CASO and CFAR-CA

Hi Kei,

When I run this locally, I get the following error message:

I'm running the visualizer locally with the instructions listed here.

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1127823/iwr6843aopevm-mmwave-demo-no-longer-displaying-radar-data-iwr6843aop

When I run the default cfg, the objects and peaks seem to look right

Can you try it locally? We've seen some problems with the visualizer in the last few weeks that we're resolving concurrently.

Best,

Nate

Hi Nathan,

Thank you for your cooperation.
I used demo Visualizer locally, but the issue was not solved.

Regarding the error message you encountered, which pre-build binary did you use xwr68xx_mmw_demo.bin or xwr64xxAOP_mmw_demo.bin?
I guess if xwr68xx_mmw_demo.bin used, missing bpmCfg message is shown.
I am using xwr64xxAOP_mmw_demo.bin and IWR6843AOPEVM.

Hi Kei,

I can confirm the behavior you're reporting. Please disable cyclic mode with the following change to the faulty configuration:

cfarCfg -1 0 0 4 2 3 0 15 0

Best,

Hi Nathan,

I tried disabling cyclic mode, then the fault was solved. Could you let me know why the fault was solved? Does range CFAR of xwr64xxAOP_mmw_demo.bin not support cyclic mode?

Hi Nathan,

Thank you for your answer. I understand.

Kei
