FreeRTOS Specific Port

Overview

This directory contains an implementation of Memfault dependency functions when a platform is built on top of FreeRTOS.

Usage

1. Add $MEMFAULT_FIRMWARE_SDK/ports/freertos/include to your projects include path
2. Prior to using the Memfault SDK in your code, initialize the FreeRTOS port.

#include "memfault/ports/freertos.h"

void main(void) {

  memfault_freertos_port_boot();
}

Heap Tracking

The memfault-firmware-sdk has a built in utility for tracking heap allocations to facilitate debug of out of memory bugs. To enable, add the following to your memfault_platform_config.h file:

#define MEMFAULT_FREERTOS_PORT_HEAP_STATS_ENABLE 1
#define MEMFAULT_COREDUMP_HEAP_STATS_LOCK_ENABLE 0
#define MEMFAULT_COREDUMP_COLLECT_HEAP_STATS 1
