[quote=“rgvandewalker, post:1, topic:358”] “Tool openocd is not available for your operating system.”

This is true as SiFive don’t currently supply a Windows binary of OpenOCD as they do for MacOSX and linux. From the JSON Arduino manifest SiFive provide:
{ "version": "b474c22b33be7fa4969c0dfa9ccf172ce1bab5d0", "name": "openocd", "systems": [ { [...] "host": "x86_64-pc-linux-gnu", [...] }, { [...] "host": "i686-pc-linux-gnu", [...] }, { [...] "host": "x86_64-apple-darwin", [...] } ] }
There’s a fair bit of detail about compiling and running OpenOCD under Cygwin in this thread which may be helpful though.
