How to use Vitis HLS IP in Python Pynq overlay Environment.

Hello everyone,

happy new year. Please guys can you help me to fix my problem. I have programmed a HLS IP for using in vivado to transfer data from PL to PS. I am using pynq overlay. When i start the IP by writing in the register of the custom ip (0x0, 1) then i cannot write anymore in the same register (0x0, 0) can please someone help to understand why how can i fix it. Thank you very much.

I have not done Vitis HLS/Pynq Overlay before. From my reading at Xilinx website, you need to update HLS IP with the FPGA bitstream first, then use Phyq Overlay to load the updated FPGA bitstream second…

From my reading at Xilinx website, you need to update HLS IP with the FPGA bitstream first, then use Phyq Overlay to load the updated FPGA bitstream second. I believe that you need to reset PL from PS side without powering off the FPGA. If your updated FPGA bitstram has no bugs, you can get things work as you expect.

Hi Jan: I will reproduce PHYQ projects you published soon. It is on my to-do-list for 2024.
