ERROR [empty-fasm]: top.fasm has no FASM features (an empty or corrupt place-and-route output, usually a build interrupted half way). Fix: run dewfpga clean and build again. https://nosey-dewdrop.github.io/dewfpga/errors/empty-fasm/Why does it happen?
make rebuilds only what is older than its inputs; a .fasm left empty by a killed nextpnr looks up to date, and turning it into frames would fail.
What is the fix?
dewfpga clean && dewfpga bit
