TM4C129ENCPDT: Tracking heap usage in run-time and printing it on console

Part Number: TM4C129ENCPDT

Hi All,

I want to track the heap usage of my code and printing it on the console like how much heap is used and how much is left. 

I tried this but did not work. https://e2e.ti.com/support/legacy_forums/embedded/tirtos/f/355/t/468277#pi320995filter=all&pi320995scroll=false

I am using TI RTOS 2.16.1.14 and xdc tool 3.32.00.

Thanks

    Hi Akhilesh,

    You can call Memory_getStats to get the totalSize, totalFreeSize, and largestFreeSize. If you what this information on the the default system heap, you can provide NULL as the first parameter (i.e. IHeap_Handle)? Note: the default system heap is used when you do malloc or Memory_alloc(NULL, ...).

    Once you have the information, you can print it to the console via System_printf. Please note that displaying characters on the CCS console can impact real-time performance since the target is paused (to allow CCS to read the memory) when this occurs.

    Hi Todd,

    Thanks. It's working now. Is there any way to track stack usage also? This way I can check whole RAM usage.
