Release Notes:

Hide
The UDMA requires buffers/data handled by the DMA to be on an address aligned according to the data size it is moving (i.e. 16-bit data buffers must be on an 16-bit aligned address). Currently the driver only has a DebugP_assert() in place to check for alignment; but we are currently not providing driver libraries with assertions enabled. The check should always be performed.

Other SPI drivers (SPIMSP432DMA, SPIMSP432E4DMA, etc) have this implemented.
