Not an expert, but I think anything compiled for the ISA implementation you have should work.

If there's an issue with RISC-V it's that it's not one ISA with additional instructions accumulating across generations (which I think describes x86), it's a core ISA with a variety of extension blocks that might or might not be present in your implementation. I think this means that any random RISC-V binary stands a greater chance of not working on a chip you've bought than e.g. any random x86 binary with an x86 chip.

x86 has this problem too. Base x86 doesn't even support floating point. (and x87 which was the og way is now basically deprecated).
