I agree with what was said from your links. The code was poorly written but that does not mean that this can't be improved once they get an active community. Sadly, right now they are inactive and I don't know why.
I think the complaints about peripheral source are valid, but they have had it running on silicon for months, so the answer to "will it work" is pretty clear.
"First of all, it is just a simple microcontroller and the implemented RISC-V instructions are not that significant for the purpose. It's like expecting the SIM cards used in mobile phones to be equivalent to PCs because they run "Java"."
Who is calling this a PC? OpenV seems to be marketing itself as a microcontroller, it keeps comparing itself to Arduino.
