Can I build my embedded firmware with nix using a Windows only toolchain?

(Fyi I just used something like the solution from the article, with the hash embedded in the binary image to be burned to ROM masks. The gaps in toolchain versioning and not building with dirty checkouts can be managed with self discipline /internal checks)

Generally development tools run fine under wine, so I'd guess it would be fine. Running a windows binary within wine within WSL on windows does seem a little insane tho!

Now I think of it, WSL can generally call out to Windows tools - you would need to run in a Windows file system mounted into WSL. It just won't port to a Linux-based CI job without Wine. The ideal is a build and test run that is reproducible in CI and locally.
