DMA Errors

Variants

InvalidAlignment(DmaAlignmentError)

The alignment of data is invalid

OutOfDescriptors

More descriptors are needed for the buffer size

DescriptorError

DescriptorError the DMA rejected the descriptor configuration. This could be because the source address of the data is not in RAM. Ensure your source data is in a valid address space.

Overflow

The available free buffer is less than the amount of data to push

BufferTooSmall

The given buffer is too small

UnsupportedMemoryRegion

Descriptors or buffers are not located in a supported memory region

InvalidChunkSize

Invalid DMA chunk size

Late

Indicates writing to or reading from a circular DMA transaction is done too late and the DMA buffers already overrun / underrun.
