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. |
