| 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=generic* |
| 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=generic 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. |
