void* heap_caps_malloc(size_t size, uint64_t capabilities); ``` 参数解释: 1. `size`:要分配的内存块的大小(以字节为单位)。 2. `capabilities`:一个 64 位整数,用于指定分配的内存块的能力。这可以是一个或多个预定义的能力值,例如`CAP_SYS_ADMIN`、`CAP_SYS_RAWIO` 等。这些能力定义了内存块...
pBuffer = heap_caps_malloc(Data_Length + 1, MALLOC_CAP_SPIRAM); if (pBuffer == NULL) { DEBUG_LOGE(UART, TAG,"Memory Allocation failed\n"); return NULL; } else { DEBUG_LOGD(UART, TAG,"*** bytes allocated via heap_caps_malloc %d address is =%p", Data_Length,pBuffer); } ...
heap_caps_malloc was called but failed to allocate1696byteswith6144capabilities. I started looking into malloc function declaration and noticed something strange: In flash_mock.cpp I have found the following: Code:Select all void*heap_caps_malloc(size_tsize,uint32_tcaps ){returnNULL; } ...

In my source code I was calling heap_caps_malloc() to allocate memory As I have enabled External ram to allocate memory In my case heap_caps_malloc() called successfully but failed to allocate the memory FYI, Heap memory was still available HEAP SIZE : 74291 bytes And I was in ne...
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() ...

I haven't been able to reproduce this in an empty project yet and probably won't have time to do so for a while but thought I'd post anyway and see if anyone else has seen `heap_caps_dump(MALLOC_CAP_8BIT)` cause the interrupt WDT to panic? I get it every time from my complex...
