Is there PS DMA on ZYNQ UltraScale MPSoC?

Jump to solution

Hi, I knew there is PS DMA - DMA330 on ZYNQ-7000, so user can use it to transfer data between PS & PL without DMA-IP on PL.

However, Is there PS DMA on ZYNQ UltraScale MPSoC?

It means that user can use the PS DMA to transfer data between PS & PL without DMA-IP on PL.

PS. I’ve studied UG1228 and get the block diagram on P8:

It seems that there are LPD-DMA(Low Power Domain-DMA) & FPD-DMA(Full Power Domain-DMA).

Are those real PS DMA? How to use it?

Any help will be highly appreciated!

@HughesYang You can reference the Zynq UltraScale+ MPSoC Technical Reference Manual (UG1085; v2.2) in Chapter 19: DMA Controller.

You can also reference the Xilinx Wiki page for details on the linux driver:  Zynqmp and Versal DMA
