Part Number: IWR6843

Tool/software: Code Composer Studio

Hi all,

I try to porting our people_count project from CLI to hard code config. I refer to your 68xx_mmwave_sdk_hcc and edit out project, After porting the project, it cannot work correctly. I enter debug mode and "out of DDR heap memory" in console. Please give me some suggestions to solve this problem. Thank you

I provide my program and information for your reference

Hi Kimi,

With this limited context, it is hard to comment on the cause of the error.

Specifically in context of the people counting demo, rather than using the hardcoding method in the HCC example, I would recommend using the simpler method explained in the following threads. This method does not require much code change as it plugs the chirp configuration commands from the configuration file directly into the CLI layer as-is and uses the existing CLI parsing infrastructure to send the configuration as usual.

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

CCS/IWR6843: Hard-code configuration commands

Please make sure to follow the instructions in the above examples carefully but basically the process is very simple as highlighted in the 3 steps below:

1. Plug-in the CLI commands in the cli.c file using the instructions provided in this example

2 Re-build the cli library for the hard-coded configuration to be added to the cli.

3. Re-build the people counting demo (or any other demo, the process is the same).

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.

Regards
