CC3220SF-LAUNCHXL: Get System Heap and Stack statics

Naga SuresH

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: CC3220SF

I am using CC3220SF - LaunchXL along with the FreeRTOS SDK.

I understand that System heap is configured from CC3220SF_LAUNCHXL_FREERTOS.icf file as defined below.

define block HEAP with alignment = 8, size = 0x00008000 (configuring to 32KB System Heap)

I am using IAR as debugger, is there any way I can get the System(controller) Heap & Stack consumption statistics on run time or based on the API calls.

Regards,

Suresh

Hi,

For these cases of probing memory consumption statistics we usually use ROV (Runtime Object View).

In the past it was supported only for TIRTOS and CCS.

Lately (3Q 2020), freeRTOS is also supported but I am not sure about IAR.

you can see some E2E threads referring to this subject:

Hi Suresh,

Depending on type of memory management model (heap type) you can use vPortGetHeapStats() API. Here is nice article about debugging stack and heap in IAR.
