lowRISC Blog Post: Tutorial For The v0.5 lowRISC Preview Release

By November 13, 2018May 12th, 2021No Comments

lowRISC is a non-profit organization whose goal is to produce a fully open source System-on-Chip (SoC) in volume. We are building upon RISC-V processor core implementations from the RISC-V team at UC Berkeley. We will produce a SoC design to populate a low-cost community development board and to act as an ideal starting point for derivative open-source and commercial designs.
This tutorial adds further functionality towards the final SoC design:

  • A simple 100Mbps Ethernet capability.
  • Remote booting via Ethernet from a Linux server.
  • Preview of interrupt driven device drivers in Linux.
  • Optimised SD-interface
  • Console defaults to keyboard and optimised VGA-compatible text display.
  • Network filing system (NFS) support in the RISCV kernel and NFS-root support scripts.
  • Multiuser system leveraging the poky Linux build system.

The build environment and pre-built images support the same platform as the previous releases, a competitively priced Nexys™4 DDR Artix-7 FPGA Board.
