Tool/software:

Hi,

Please help to tell me what memory allocate function in R2944 can use to replace Memory_alloc() in R1843?

My SDK is mmwave_mcuplus_sdk_04_06_00_00_01.

malloc() or 

HeapP_alloc() or
MemoryP_ctrlAlloc() or
Thanks,
Bolong

    Hello,

    For now try HeapP_alloc() for a replacement as it provides similar functionality with heap control. It is good for general purpose allocations. Ensure that the heap is configured properly as well.

    Hi,

    If using malloc() function in R2944 to replace Memory_alloc() in R1843 will make bugs or not?

    Regards,

    Hello,

    MemoryP_xx is not used in the SDK so I would not use it. The HeapP_alloc function is defined in HeapP_freertos.c at the following path.

    C:\ti\mmwave_mcuplus_sdk_04_07_01_03\mcu_plus_sdk_awr294x_10_01_00_04\source\kernel\freertos\dpl\common\HeapP_freertos.c

    You can familiarize yourself with the code here.

    Is there a specific reason you want to use malloc()? Of course there is a possibility that this will introduce some bugs if making that change. I originally recommended HeapP_alloc()

    Best,
