RIEC-V is as far as I know very new as a processor.
This means most of your software that works on Linux, Windows, Mac, Android or anything similar doesn't do so on the new processor.
This means you need developer who will port it or write new software for it. While crosscompiling is possible it is usually easier to have real hardware to test on. Not even to write the software on that device. You still can write it on your x86-64 pc and then either compile it on the RISC-V pc or crosscompile and test it only on the RISC-V pc.
For people who want to do this,it is targeted I think.
Tech enthusiasts who like new stuff.
