CC2642R: How to Measure Maximum Heap Stack Usage

Shunsuke Fujitaka

Part Number: CC2642R

Tool/software: IAR(v9.40.2)

Hi everyone,

I currently use the SDK version simplelink_cc13xx_cc26xx_sdk_7_10_01_24 and IAR Version 9.40.2.
Previously, we used ROV for Heap measurements at old IAR version.
However, I understand that the current IAR version does not support ROV.
Therefore, as a measuring method of Heap Stack, we used the following structure and the measuring method which is described in the manual.

dev.ti.com/.../debugging-index.html

However, while it can measure the instantaneous usage of the Heap Stack, it cannot measure the maximum usage.
I would like to know if there is any way to measure the maximum usage of Heap Stack.

Hi Shunsuke-san,

I'm not personally aware whether that SDK has a limit with ROV being non-functional on IAR 9.40.2. Can you help me understand where that perception is coming from?

For clarity, 7.10.01.24 should be used with AIR version 9.32.1. May be worth trying this first as well.

Hi Evan,

Thank you for your supporting.

As for the ROV not being able to use the new IAR, I checked the following site.

SIMPLELINK-CC13XX-CC26XX-SDK: IAR TI-RTOS plugin failing with SDK 6.30 - Bluetooth forum - Bluetooth®︎ - TI E2E support forums
However, there is no other measurement method for HeapStack, so I asked in this form.

For clarity, 7.10.01.24 should be used with AIR version 9.32.1. May be worth trying this first as well.

→It has been disabled since version 9.** of IAR, so there is no point in trying.
