CONFIG_HEAP_MEM_POOL_SIZE¶

Heap memory pool size (in bytes)

Type: int

Help¶

This option specifies the size of the heap memory pool used when
dynamically allocating memory using k_malloc(). The maximum size of
the memory pool is only limited to available memory. A size of zero
means that no heap memory pool is defined.
