# Heap Task Tracking Example
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
The example creates a task which allocates random amount of memory in each iteration and demonstrates use of internal API to get heap info on per task basis running in a system.
|
||
|
|
|
||
|
|
Heap task tracking feature has dependency on some of the internal heap debugging features (e.g. heap poisoning) which allows to store task control block in metadata of each heap block.
|
||
|
|
|
||
|
|
This adds small memory overhead on per heap block and hence this feature should be used for debugging purpose only.
|
||
|
|
|
||
|
|
### Configure the project
|
||
|
|
|
||
|
|
To change the `Heap Corruption Detection level`, open the project configuration menu (`idf.py menuconfig`).
|
||
|
|
|
||
|
|
Navigate to `Component config -> Heap memory debugging` menu. In `Heap corruption detection` menu select either "Light Impact" or "Comprehensive".
|
||
|
|
|
||
|
|
**Note:** Enabling “Comprehensive” detection has a substantial runtime performance impact.
|
||
|
|
|
||
|
|
### Build and Flash
|
||
|
|
|
||
|
|
Run `idf.py -p PORT flash monitor` to build and flash the project..
|
||
|
|
|
||
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
||
|
|
|
||
|
|
See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
