IWR6843AOPEVM: Running out-of-box demo

Hello.

Can you provide an image of your current set up as well as the current list of ports in your device manager?  It looks like the GUI isn't able to parse the UART output from the device so please also make sure that you have the correct UART drivers installed that are provided in the out of box user guide.

Sincerely,

Santosh

Hi Santosh,

Above images show my setup. As I noted before, UniFlash was able to recognize my set up. And after I made the suggested in https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1137996/iwr6843aopevm-connecting-mmwave-industrial-visualizer-to-target-on-ubuntu?tisearch=e2e-sitesearch&keymatch=UBUNTU# I was able establish connection from the Visualizer to the board. Let me know if you need any other information about my setup.

Thanks,

Rama

Hello.

According to your setup, it looks like the S2 switches on the AOP are incorrect as they should be OFF/ON/N.A/N.A for S2.1/S2.2/S2.3/S2.4, respectively.  However, all of your switches are in the OFF position.  It also looks like you are still in flashing mode instead of functional mode based on the jumpers on the ICBoost, but the picture was a bit blurry when I zoomed in so please correct me if I am mistaken.  Please reference the EVM setup guide for how to do this with the ICBoost, linked here.  Also for some clarification, does this error occur after you press the connect button or when you send the cfg?

Sincerely,

Santosh

Hi Santosh,  

I did the switch setting watching the video at https://training.ti.com/hardware-setup-mmwaveicboost-and-antenna-module  and this is what I saw at 9:30 mark:

Here is the SOP jumper setting:

Looking at the documentation

I feel the jumper setting I have corresponds to 001 (SOP mode 4) = functional mode

This is what I see in SWRU546E page 72 for S1 and S2 setting on IWR6843AOPEVM:

Now I see the difference. So, should S2.2  OFF for flashing and then set to ON for functional mode? I thought the only thing that needs to be changed from flashing mode to functional mode was SOP2 jumper setting. on MMWAVEICBOOST board. Can you please clarify?

Thanks,

Rama

PS: I get the same error as I got before with S2.2 set to ON and when I press "Start without Send Code" button

Hi Santosh,

Which specific configuration file should I be using just to get out-of-box demo up and running. There are a number of files with cfg extension in the folder you mentioned and I am not sure which one I should be using. I couldn't find a document that provides such instructions.

Thanks,

Rama

I continue to get the same error even after selecting a configuration and press the Start and Send Configuration. I am wondering if the changes made to gui_main.py to address the connection issue has impacted anything else. Here is the modified gui_main.py

Hello.

My apologies for the confusion.  For the profile configuration, look in the sdk_install/packages/ti/demo/xwr64xx/mmw/profiles folder as the out of box for AOP does not use the DSP.  Use the one with the aop ending in the filename.  Make sure you are also flashing the out of box binary with the aop ending from the toolbox.

Sincerely,

Santosh

Hi Santosh, 

I have flashed IWR6843AOPEVM with out-of-box-demo using UniFlash. I apologize; I am not sure I understand what you mean by "For the profile configuration, look in the sdk_install/packages/ti/demo/xwr64xx/mmw/profiles folder as the out of box for AOP does not use the DSP.  Use the one with the aop ending in the filename. " . 

Can you please tell me which specific cfg file i should be using for SDK Out of Box Demo? Please provide the specific name of the file. Here is the list of files I see in the folder you mentioned:

Which one of the above files should I be using when I press the button Select Configuration on the Visualizer?

Thanks,

Rama

PS: I tried profile_3d.cfg and the demo seems to be running. I see the point cloud as shown below:

Starting from your sdk install location, follow this filepath to the profiles folder, and choose the profile_3d_aop.cfg.  You went to the xwr68xx folder instead of xwr64xx folder. 

Sincerely,

Santosh

Thanks for the clarification, Santosh. I thought I should stick with xwr68xx for IWR6843AOPEVM. I still see the "invalid TLV type" warnings and "Parsing Error". Don't know what they are and ignoring for the time being. For now, I am not blocked. I will try to proceed with other demos. 

Thanks for your patience in helping this newbie.

No problem.  That is a bit confusing, as the reason it is there is due to the fact that this demo for the AOP does not use the DSP, and is lumped into the 64 folder in the SDK.  Let me look into the TLV issue and get back to you on that.

Sincerely,

Santosh

I understand. I am an ex TIer and I have been using TI products since early 80s.  Learning never stops and the sun never sets for engineers. :) 

Thanks for the suggestion. The change did make a difference but there were few of those "invalid TLV type" warnings and related errors when I started the demo. I will ignore them for the time being and I will mark your last response as "resolved my issue". Thanks for your help.
