UDMA and UDMAP : Descriptors and TRs required to be returned unfragmented
The UDMA and UDMAP require that the descriptors and TRs are placed in a memory subsystem that returns the descriptor or TR without any fragmenting of the descriptors. However, there are some memories that contain a fragmentation bridge, which makes them not available for holding the descriptors and TRs.
For this device, the R5 TCM memory cannot hold descriptors or TRs for UDMA or UDMAP
None
