IWR6843AOPEVM: mmWave Demo Visualizer can't connect to data port

Nayab Khan

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVE-SDK

When I try to connect to the IWR6843AOPEVM module via mmWave Demo Visualizer, it connects successfully to the CFG_port_Transport but keeps retrying to connect to the DATA_port_Transport (see screen shots below).

So far here are the steps that I've taken:

1. I've successfully uploaded the packages\ti\demo\xwr64xx\mmw\xwr64xxAOP_mmw_demo.bin image onto the IWR6843AOPEVM module.

2. Switched SOP2 to OFF position (SOP0, SOP1 are also off)

3. In CHROME go to mmWave Visualizer https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer_IWR6843AOP/ver/1.0.0/

4. Select ports as below screen shot.

5. The CFG port is successfully connected but the data port doesn't (see image below). The status at the bottom of the screen says "waiting for data" for that port.

Please help.

Hi Nayab,

We recently identified an issue in MMWAVE-SDK 3.2.0.6_AOP which can cause the software start-up sequence to hang and potentially lead to the issue you are seeing.

We have posted the details of the issue and corresponding fix in the following post. Customers can follow the instructions provided in the post to apply the fix on top of SDK 3.2.0.6_AOP. The fix will be eventually included in a future SDK release for AOP devices.
While you can follow the instructions provided in the post to apply the fix, note that the updated C file and AOP demo binary: xwr64xxAOP_mmw_demo.bin are available in the 68xx AoP - mmWave SDK Demo Lab in mmWave Industrial Toolbox 4.0.1

[FAQ] IWR6843AOPEVM: MMWAVE-SDK 3.2.x startup sequence needs to be updated for IWR6843 ES1.0 and IWR6843AOPEVM ES1.0

I would recommend you to flash the pre-compiled updated demo binary from 68xx AoP - mmWave SDK Demo Lab and re-test with mmWaveDemoVisualizer-AOP.

Thanks

-Nitin

Hi Nayab,

W.R.T. your original post, please note that while you should test with the updated demo binary as suggested above, I just wanted to make sure you are not missing the basic setup requirements as given below.

Did you press the "SEND CONFIG TO MMWAVE DEVICE" button in the configure Tab? The data COM port shows a green connected status only after the demo firmware starts sending point cloud output, for which you need to send the input configuration using the "SEND CONFIG..." button.

Thanks

-Nitin
