Hi, After following the tutorials, I have successfully built and ran some DPU example notebooks on my ZCU104, image version v2.7.0, DPU-PYNQ v1.4.0. Now I am going to make it working on PYNQ-ZU. After rebuilding the DPU, I copied it and installed it by using `pip3 install /home/xilinx/DPU-PYNQ`, without any error. But I don’t understand how the command `pynq get-notebooks pynq-dpu -p .` works. I tried the command then it showed: ```auto root@pynq:/home/xilinx/jupyter_notebooks# pynq get-notebooks pynq-dpu -p . Delivering notebooks './pynq-dpu'... The notebooks module 'pynq-dpu' could not be delivered. The module has no notebooks, or no valid overlays were found ``` Then I tried to copy the notebooks from my ZCU104 to my PYNQ-ZU, ran it, and it showed ```auto FileNotFoundError Traceback (most recent call last) in 1 from pynq_dpu import DpuOverlay ----> 2 overlay = DpuOverlay("dpu.bit") /usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq_dpu/dpu.py in __init__ (self, bitfile_name, dtbo, download, ignore_version, device) 89 abs_bitfile_name = os.path.join(OVERLAY_PATH, bitfile_name) 90 else: ---> 91 raise FileNotFoundError('Cannot find {}.'.format(bitfile_name)) 92 super(). __init__ (abs_bitfile_name, 93 dtbo=dtbo, FileNotFoundError: Cannot find dpu.bit. ``` How to make my PYNQ-ZU running DPU examples? Thank you in advance. ---

The problem is solved by copying the bitstream ```nohighlight # on PYNQ-ZU, or custom platform cd /home/xilinx/DPU-PYNQ/boards/Pynq-ZU sudo cp dpu.bit dpu.hwh ../vitis_platform/dpu/dpu.tcl binary_container_1/dpu.xclbin /usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq_dpu ``` ---

@haipnh , Can you provide guidelines on how to make custom platform for pynq-zu? Thanks in advance. Eli ---

Hi @3togo , What do you mean “custom platform for PYNQ-ZU”? Do you want to custom the base overlay for PYNQ-ZU, or build DPU overlay for PYNQ-ZU? If you mean building DPU overlay for PYNQ-ZU, you can review the commits which I pushed to [GitHub - haipnh/DPU-PYNQ at pynqzu](https://github.com/haipnh/DPU-PYNQ/tree/pynqzu). You can simply download my repository, checkout the “pynqzu” branch and start building it by “make BOARD=Pynq-ZU”. If you have further questions, feel free to ask. ---

@haipnh , Your pynq-zu branch is very helpful. I managed to build DPU Overlay as per your advice. Out of curiosity, where did you get the information of these two files: dpu\_conf.vh and prj\_config for Pynq-ZU? Thanks again Eli ---

Hi, PYNQ-ZU uses XCZU5EG, which is a variant in the Zynq Ultrascale+ product line. Xilinx provides ZCU102 and ZCU104 as reference platforms for Zynq Ultrascale+ based development. So I just ported those files from ZCU102 and ZCU104 projects.
