`heap_caps_malloc` 函数允许你为分配的内存块指定一组能力(capabilities)。这些能力定义了该内存块可以执行的操作,例如读、写、执行等。这使得内存分配具有更高的安全性和灵活性。 函数的原型通常如下: ```c void* heap_caps_malloc(size_t size, uint64_t capabilities); ``` 参数解释: 1. `size`:要分...
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() ...
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...
void*heap_caps_malloc(size_tsize,uint32_tcaps ){returnNULL; } Is this function deprecated? what is flash_mock.cpp? In the heap_caps.c I have also found the real heap_caps_malloc function declaration: Code:Select all IRAM_ATTRvoid*heap_caps_malloc(size_tsize,uint32_tcaps){void* ptr...

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...
