DMA stuck when using custom HLS ip

[cathalmccabe]

Are you setting TLAST in your HLS stream, and was this the tutorial you were following?:

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…

The DMA expects to see TLAST in the AXI stream set to 1 for the last value of the transfer.
