ERROR: Can't load module `./dsp-ff'

[alanvgreen]

I get the following error when building hps_accel:

6.2. Continuing TECHMAP pass.
Using template VHI for cells of type VHI.
Using template VLO for cells of type VLO.
No more expansions possible.

• I used cd proj/hps_accel; make gateware
• I am on commit b77f26db0a78417f0f32e92ac2d9ef809db656c0.
• I have run scripts/setup
• I have run scripts/install_oxide update
• There is no file named dsp-ff.so anywhere in the CFU-Playground tree

Am I missing a yosys update or build flag?

I probably forgot to add the new plugin to the install_oxide flow.

After applying the changes from #540 I was able to build the plugins correctly, so the dsp-ff.so file showed up in ./third_party/usr/local/share/yosys/plugins/dsp-ff.so and the error during synthesis was gone.

@alanvgreen can you update the status here when you get a chance?
