Project Organization

  • boot: This folder is the central place for all built files. This includes the kernel image, rootfs, gateware, etc. This directory also includes everything the TFTP server has to access.
  • build: Docker build environment.
  • buildroot: Buildroot configuration files.
  • doc: Documentation.
  • doc/copying: Licenses.
  • gateware: FPGA source.
  • gateware/rtl: Verilog sources.
  • gateware/rtl/spi: SPI code (from another repo)
  • linux: Software that runs on the controller.
  • opensbi: OpenSBI configuration files and source fragments.
  • swic: Code that runs on the PicoRV32 soft core.
