Implementing SiFive FPGA Pmod shell into Rocket chip

[Jack Davidson]

Hi all, 

I'm looking to implement FPGA Pmod support into an existing Rocket chip configuration, and found the SiFive overlay shells here. How should I go about attempting to implement these, or is there a better way to add this functionality? I haven't come across any methods that seem appropriate

I'm new to RISC-V, so any help or suggestions would be appreciated!

Thanks,

Jack

Did you see this already in case it's of any use?

I did see that, but have had trouble making use of it. Ideally the RISC core would use one of the fabric-connected Pmod ports, so AXI wouldn't be a factor unless I'm mistaken.
