No Pynq driver generated

[dprzewlocka]

Hello! I have a strange problem generating the Pynq driver:

I use the variation :) of the "Building the Streaming Dataflow Accelerator" notebook but I only generate the streamlined onnx model and then I do folding with my own parameters in an 'old way' (for some reason the folding parameters that are automatically generated violate the FINN rules)

• To generate the streamlined model I use the following configuration:

cfg_estimates = build.DataflowBuildConfig(
  output_dir  = estimates_output_dir,
  mvau_wwidth_max  = 80,
  target_fps = 100,
  synth_clk_period_ns = 10.0,
  board ="ZCU104",
  steps  = build_cfg.estimate_only_dataflow_steps,
  generate_outputs=[
      build_cfg.DataflowOutputType.ESTIMATE_REPORTS,
      build_cfg.DataflowOutputType.PYNQ_DRIVER,
  ]
)

• Then I take the step_target_fps_parallelization.onnx model and do folding, and finally I generate the hardware

• But somehow my synth onnx model does not contain the path to Pynq driver, the metadata_props are as follows:

[key: "floorplan_json"
value: "/tmp/finn_dev_vision/vitis_floorplan_e1rc2ta2/floorplan.json"
, key: "vivado_pynq_proj"
value: "/tmp/finn_dev_vision/vivado_zynq_proj_m5xd8106"
, key: "bitfile"
value: "/tmp/finn_dev_vision/vivado_zynq_proj_m5xd8106/resizer.bit"
, key: "hw_handoff"
value: "/tmp/finn_dev_vision/vivado_zynq_proj_m5xd8106/resizer.hwh"
, key: "vivado_synth_rpt"
value: "/tmp/finn_dev_vision/vivado_zynq_proj_m5xd8106/synth_report.xml"
, key: "platform"
value: "zynq-iodma"
]

What am I missing that the Pynq driver is not generated? Thanks for your help! I'm using the FINN v0.7.
