How do I use RISC-V FPGA in the other board instead "Nexys A7" board?
Sorry for my late replay, I've just seen your post.
It's a larger board than Nexys A7 (larger FPGA, memory...) so I understand it should be possible and not complex. You could start from the VeeR EH1-based SoC (provided in v2.2 and also in v3.0 of the RVfpga materials). Note that at least you'll need to change the constraints file "rvfpganexys.xdc". Please let us know if you need any other guidance and please inform us of your progress.
