OpenPiton FPGA SoC Platform
OpenPiton is the world's first open source, general purpose, multithreaded manycore processor. It is a tiled manycore framework scalable from one to 1/2 billion cores. Currently, OpenPiton supports the 64bit Ariane RISC-V processor from ETH Zurich. To this end, Ariane has been equipped with a different L1 cache subsystem that follows a write-through protocol and that has support for cache invalidations and atomics.
To build platform specific library and firmwares, provide the
PLATFORM=fpga/openpiton parameter to the top level make command.
Platform Options
The OpenPiton platform does not have any platform-specific options.
Building Ariane FPGA Platform
Linux Kernel Payload
make PLATFORM=fpga/openpiton 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.
