For future readers, the screenshots above are probably from the Linux SDK documentation:

You can find additional information about allocating memory regions in the AM62x academy, multicore module, "How to allocate memory" section:

Hello,

Please start by reading through the "How to allocate memory" pages that I linked above. Then you can ask followup questions if there is anything else that is not clear.

Regards,

Nick
