Just wanted to let you know that for ADI's AXI DMAC IP I was only able to make DMA transactions using udmabuf 1.4.6. I tried it for zynq 7000 vivado 2019.1. I tried u-dma-buf master branch and also version 1.4.8 for both of these my udmabuf didnt populate. Then I tried udmabuf 1.4.6 on the same HW and my dmabuffer began to fill with data.
