/* This file implements the heap related functions that are called by FreeRTOS.
|
|
* ESP-IDF provides its own heap containing memory with different capabilities
|
|
* (see esp_heap_caps.h). Thus, this file maps a subset of the ESP-IDF heap to
|
|
* act as the FreeRTOS heap.
|
|
*
|
|
* All dynamic allocation done by FreeRTOS should be placed in internal 8-bit
|
|
* accessible RAM (i.e., using the MALLOC_CAP_INTERNAL|MALLOC_CAP_8BIT flags).
|
|
* This is due to the fact that FreeRTOS objects (e.g., task stacks, TCBs,
|
|
* queues etc) must be accessible even if the cache is disabled. Therefore, the
|
|
* heap that is made available to FreeRTOS for dynamic allocation is a subset of
|
|
* the ESP-IDF heap (where all MALLOC_CAP_INTERNAL|MALLOC_CAP_8BIT memory is
|
|
* made available to FreeRTOS for dynamic allocation).
