Building for RISC-V ? #72

Open udo-munk opened 1 month ago

udo-munk commented 1 month ago

I'm trying to build one of my z80pack VM's for the RISC-V instead of the ARM cores. Looks like FatFs is not prepared for this yet?

Right. I haven't even begun to look at RISC-V yet, and it might be a while before I have time. However, if someone else wants to take a crack at porting it, you are welcome to submit a Pull Request.

Understandable. I had a brief look, that is the part the deals with interrupts, DMA and all the low level stuff, must be relearned for RISC-V, if one isn't familar with the architecture already. Certainly not a quick over the weekend project.
