Deploy BNN model on FPGA AC701

[lloo099]

Hi all, as I want to deploy my NN model by using FINN. If it is possible to deploy it to AC701 which doesn't include PS? If Yes, how to do it?
Another question about FINN, what kind of model I can deliver to Brivitas? Any trained model is suitable for it? After translating to ONNX format, how to generate HLS IP by using FINN? I am still confused on it, although read some tutorials on your website.
Thanks,

Hi @lloo099 , it is possible to deploy FINN-generated accelerators on devices without any PS as well, though it takes a bit more effort. The idea is to stop the build flow at the IP block design (also called stitched IP) generation stage, which gives you an IP block with AXI stream-in stream-out interfaces, and integrate that manually into your FPGA design. Although not yet released, we have an upcoming tutorial about this here thanks to contributions from @jterry-x : https://github.com/jterry-x/finn-examples/tree/main/build/fpga_flow

I'm not sure if I understood your question about Brevitas, but the FAQs 2,3,4 in https://finn.readthedocs.io/en/latest/faq.html might be relevant.

Some suggestions:

• Did you try to run apt-get update manually?
• Do you run the Docker container as a non-root user (see here)?
• Did you try to pass the build directory path (where the build.py file is located) without the trailing slash (e.g. "/home/jjc/path_to_dir")?

Yes, I already run apt-get update and docker run hello-world without root. Then run ./run-docker.sh build_custom $/home/jjc/Desktop/finn-examples-main/build/fpga_flow [where the build.py file is located] Last error has solved, but still cannot process run-docker.sh well. Pls help me to check these in the following:

Hi @fpjentzsch , The program can run normally when I simply run bash ./run-docker.sh, but it was interrupted later. It cannot find these files, but I install my Vivado without any modifications.

Do u know how to deal with it?

@lloo099 I think Vitis version >= 2020.2 is not well supported for FINN now.

@lloo099 I think Vitis version >= 2020.2 is not well supported for FINN now.

think so
