Ariane FPGA SoC Platform

Ariane is a 6-stage, single issue, in-order CPU which implements the 64-bit RISC-V instruction set. The Ariane FPGA development platform is based on FPGA SoC (which currently supports only Genesys 2 board) and is capable of running Linux.

The FPGA SoC currently contains the following peripherals:

  • DDR3 memory controller
  • SPI controller to conncet to an SDCard
  • Ethernet controller
  • JTAG port (see debugging section below)
  • Bootrom containing zero stage bootloader and device tree.

To build platform specific library and firmwares, provide the PLATFORM=fpga/ariane parameter to the top level make command.

Platform Options

The Ariane FPGA platform does not have any platform-specific options.

Building Ariane FPGA Platform

Linux Kernel Payload

make PLATFORM=fpga/ariane FW_PAYLOAD_PATH=<linux_build_directory>/arch/riscv/boot/Image

Booting Ariane FPGA Platform

Linux Kernel Payload

As Linux kernel image is embedded in the OpenSBI firmware binary, Ariane will directly boot into Linux directly after powered on.
