Ray,
We’d be happy to support Windows with the package, but the problem is that all our flows so far depend on compiling from the sources: riscv-gnu-toolchain and openocd in http://github.com/freedom-e-sdk. The Arduino package basically is just a distribution of those sources compiled on the target host OS.
We’ve heard reports of people getting riscv-gnu-toolchain to compile under Cygwin environments on Windows, but not in a way that we’ve found foolproof for Windows. We’ve also heard of a few other techniques which we are experimenting with, but so far haven’t found a really robust way to do the compilation under Windows.
If you have ideas, we’d be happy to hear them.
Thanks,
Megan
