[Page 2] [PATCH v3 0/3] Add Xilinx AXI Video DMA Engine driver. ° See Vivado Design Suite User Guide: Partial Reconfiguration (UG909) [Ref 6] for the complete list. This split was mainly done to simplify the driver and because the direct register mode would be much easier to write and debug. I have gone through probably a couple hundred websites and there is always conflicting information on those. Now I manage the axi dma module form the user space, writing and reading the control/status registers of the axi dma mapped on /dev/mem. 0) for some of my projects and to my no surprise found Xilinx AXI-DMA not working again.
