Use the ``MALLOC_CAP_DMA`` flag to allocate memory which is suitable for use with hardware DMA engines (for example SPI and I2S). This capability flag excludes any external PSRAM.
.. only SOC_SPIRAM_SUPPORTED and not esp32::
.. only:: SOC_SPIRAM_SUPPORTED and not esp32
The EDMA hardware feature allows DMA buffers to be placed in external PSRAM, but there may be additional alignment constraints. Consult the {IDF_TARGET_NAME} Technical Reference Manual for details. To allocate a DMA-capable external memory buffer, use the ``MALLOC_CAP_SPIRAM | MALLOC_CAP_DMA`` capabilities flags; the heap allocator will take care of alignment requirements imposed by the cache and DMA subsystems. If a peripheral has additional alignment requirements, you can use :cpp:func:`heap_caps_aligned_alloc` with the necessary alignment specified.

EDMA 硬件功能可以将 DMA buffer 放置在外部 PSRAM，但可能存在一定的对齐限制，详情请参阅 {IDF_TARGET_NAME} 技术参考手册。若要分配一个可用 DMA 的外部 buffer，请使用 ``MALLOC_CAP_SPIRAM | MALLOC_CAP_DMA`` 属性标志，堆分配器将处理 cache 及 DMA 子系统的对齐要求。如果某个外设有额外的对齐要求，可以调用 :cpp:func:heap_caps_aligned_alloc 并指定必要的对齐方式。
