I've installed Glasgow and YoWASP in a new virtual environment:

  DEPRECATION: crcmod is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

When I attempt to build a bitstream for an applet (I've tried uart and jtag-probe), I get the following error:

In issue #298, where a similar problem was reported, I've mentioned that the issue was fixed with yowasp-yosys==0.23.dev444. If I downgrade YoWASP Yosys to that version, synthesis succeeds. However, it fails with yowasp-yosys==0.23.0.0.post486 or yowasp-yosys==0.25.0.102.post487.dev0.

Running glasgow build --rev C1 -t zip uart produces this archive: uart.zip

[whitequark]

This is a YoWASP issue. YoWASP no longer mounts /tmp itself, and Yosys abc integration uses that to pass intermediate data around.

YoWASP/runtime-py#1

[whitequark]

Could you recheck using the following yowasp-runtime wheel, please?
wheel.zip

[VioletEternity]

I can build a bitstream with this wheel.

[whitequark]

I've released yowasp-runtime with this patch. Everything should work after pip install -U yowasp-runtime (or just reinstall the venv).
