Unaligned Transfers of Small Payloads Fail on SG-DMA - Unaligned Transfers of Small Payloads Fail on SG-DMA
Description The Scatter Gather DMA SOPC Builder peripheral does not correctly handle unaligned transfers with small payloads. A payload length smaller than the data width causes erroneous data transfers. Resolution Avoid using DMA devices to transfer small payloads. If absolutely necessary, for a 32-bit SG-DMA, a minimum length of 4 bytes guarantees that data is transferred correctly.
