To allocate a DMA-capable external memory buffer, use the ``MALLOC_CAP_SPIRAM`` capabilities flag together with :cpp:func:`heap_caps_aligned_alloc` with the necessary alignment specified.Baldhead Posts: 477 Joined: Sun Mar 31, 2019 5:16 am Location: Brazil Re: heap_caps_malloc() ...

Fyi, esp-idf/components/esp32/heap_alloc_caps.c gives a good overview; the regions struct array defines what memory is available, the start of heap_alloc_init disables regions that are reserved. zizoalbert Posts:7 Joined:Tue Jan 03, 2017 10:11 am ...
