Tool/software: Code Composer Studio

Hi Experts,

I tried to modify the MMWave Demo to bypass the CLI configuration and use a fixed configuartion.

I followed the “How to bypass CLI” steps from the SDK

... /ti/mmwave_sdk_03_02_00_04/packages/ti/demo/xwr64xx/mmw/docs/doxygen/html/index.html

I haven't been able to get it to work yet because the given description of the different steps are very rudimental and difficult to implement.

Do you have a more detailed explanation or maybe an example code?

For example, the guidance says "call MmwDemo_openSensor" and then "call MmeDemo_startSensor". Is this correct? In my opinion the config_Sensor has to be called in between.

By the way I have some debug issues which makes it even more difficult to analyze the code. I turned the optimization level to zero but the debugger still does not halt at breakpoints.

Thaks,

Lukas

Hi Lukas,

I would recommend looking at the Gesture Recognition Lab on the Resource Explorer. This Lab does use a hard-coded configuration which is in the cli.c file. Let me know if you have more questions on this.

For debugging capability you will need to remake the CLI utility or the driver you are working after first removing the "-O3" optimizations from the .mak file. Simply remove the -O3 and then run a gmake clean all and then you should be able to step through code in the utility/driver in CCSTUDIO.

If you need clarification on any of the above items please let me know.

Regards,

Hi Akash,

thaks for your reply.

Your link to the gesture recognition lab does not work. Anyway, I have taken a look into the gesture recognition lab from my SDK but the mmw_cli.c is not with a hardcoded configuartion.

For debugging I tried the steps you mentioned but it still does not stop. I turned the optimizatin off in the properties and added gmake clean to the build properties. Maybe I did anything wrong. Can you please give a step by step advice.

Kind regards,

Lukas

Hi Akash,

do you have any advice?

Hi Lukas,

If your objective is to hardcode the configuration so that the sensor starts automatically with a pre-defined configuration, you can look at the multiple E2E threads on this subject on this forum. Here are a couple of such threads which discuss this topic and the provided solution:

CCS/IWR1642BOOST: How to run independently from the host computer

CCS/IWR6843: Hard-code configuration commands

To get an example of this approach with configuration commands that work with the latest SDK, please look at the 68xx AoP_ODS - Multiple Gesture and Motion Detection Lab in Industrial Toolbox.
