How to build my own overlay for pynq-dpu

yss9701 · November 22, 2020, 2:30am

I want to build my own overlay that contains dpu and other ip, such as mipi, hdmi. Now I use vivado 2019.1, petalinux 2019.1, HLS 2019.1, because my pynq image is v2.5. I update my image using the “Quick Start” on DPU-PYNQ git, and it is normal.
But I want to use my own overlay. I see that if I want to download the overlay contains dpu, it must have a xclbin file. So do I need Vitis 2019.2 to compile it ? Is there a flow for reference? Can I implement it with other 2019.1 tools ?
Can I use DNNDK? But when I download the overlay.bit , it said that xclbin file does exist. What files do I need to download overlay with DNNDK environment ?

Hi @yss9701,

I guess you are looking for the Vivado/Vitis flow for the pynq-dpu? The following link directs to the Vivado design on different platforms such as KV260, ZCU104 and Ultra96. I haven’t tried yet, but hope it helps to some extent.

# DPU Hardware Design

Make sure you have cloned this repository onto your host machine. We will
leverage the DPU IP officially released in the Vitis AI repository, so we
need to populate the submodule in DPU-PYNQ repository.

If you have not cloned the repo yet:

```bash
git clone --recursive --shallow-submodules https://github.com/Xilinx/DPU-PYNQ.git
cd DPU-PYNQ/boards
```

If you have already cloned the repository, make sure submodules are loaded:

```bash
cd DPU-PYNQ
git submodule init
git submodule update
```

Louis
