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.
