My application requires IRAM memory, but when I use heap_caps_calloc(1, 784, MALLOC_CAP_IRAM_8BIT) it returns 0. This is on a WROVER. When using heap_caps_calloc(1, 784, MALLOC_CAP_INTERNAL | MALLOC_CAP_8BIT) I get a valid return pointer. Why the differences, what am I missing...

@czuvichDepending on the SDK versionESP.getFreeHeap()will return values calculated differently and may deceive. Until this is stabilized, I'll keep usingheap_caps_get_free_size(MALLOC_CAP_INTERNAL)instead which sticks to the historical behaviour. ...

Fyi, from what I remember the amount of D-port RAM is 328K at maximum; the rest is IRAM, cache etc. We actually feed the free IRAM into the dynamic memory allocator as well; you can allocate it using pvPortMallocCaps(size, MALLOC_CAP_32BIT). (Or at least, you should be able to...
