Applies to: PL330 AXI DMA Controller
According to PL330 TRM page 2-7, AXI identification tags of transactions that are issued by PL330 are defined as follows: - DMA channel thread access -> the same number as DMA channel - DMA manager thread -> the same number as the number of DMA channels that DMAC provides Is it possible for user to change these identification tags as they like?
Unfortunately, no. These values are fixed by the rtl and are not available as a user-configurable option. Both the Channel and Manager threads rely on the IDs being known values - ID = Channel number for the Channel thread and ID = Total number of channels for the Manager thread.
