  • Recommendations for RISC-V on FPGA
    7 projects | /r/FPGA | 8 Mar 2023
    Hello. I'm looking into implementing RISC-V on an FPGA for a school project. The two repos I'm looking into using are the Ariane and RocketChip repos. Both look actively maintained, but RocketChip has more recent releases, and it's used by this other repo that creates a block design in Vivado with the RISC-V RTL. However, we would also like to be able to make changes to the core, and I'm afraid that scala/Chisel might be difficult to learn. Ariane looks like SystemVerilog while RocketChip is mostly Chisel. Does any have recommendations on which RISC-V repo would be good to use for a project?

  • can one run one a linux distro like debian on an fpga?
    1 project | /r/FPGA | 9 Nov 2022
    I know it would run slowly, im not interested in performance, just curious about fpga capabilities. I found the following project where apparently they instantiate a Rocket chip core and are able to run debian on it. Unfortunately there are no demo images or video, and i dont own a xilinx board, so i dont know what the system is capable of doing. Could one install a lightweight desktop environment or install packages using apt?

    But to save time, since you already have the Eugene Tarassov repo working running linux, you could look into modifying the bootrom for your needs. For example, you could take out all the stuff about loading files from SD card etc. and just include kprint.h and the bare minumum you need to print out over UART.
