Hi @S_D,

I suggest you check out this tutorial

Tutorial: using a HLS stream IP with DMA (Part 1: HLS design)

Tutorial: using a HLS stream IP with DMA tutorial (Part 1: HLS design) In a previous tutorial I showed how to use the AXI DMA to stream data between memory to AXI stream interfaces. The DMA tutorial used an AXI stream FIFO to do a loopback test to show how to use the DMA. This tutorial will show how to create and add a HLS IP with an AXI input stream, and AXI output stream. This tutorial will be split into two parts. This part 1 shows how to build the HLS IP, part 2 shows how to build the Vivad…

You will need to provide the TLAST, otherwise, the DMA will not work correctly.
