When using the MPMC SDMA with a buffer descriptor which points to a zero-length buffer, data is corrupted. How do I resolve this issue?
The MPMC SDMA will not support dummy buffer descriptors at this time. Dummy buffer descriptors point to data buffers with a length of 0.
The MPMC data sheet will be updated to reflect this limitation, starting with MPMC v5.02.a, to be released in EDK 11.1.
