3Openpiton RISC-V SoC
4====================

Tianrui Wei2ef594d2021-07-01 12:54:19 +0800[diff] [blame]6OpenPiton is an open source, manycore processor and research platform. It is a
7tiled manycore framework scalable from one to 1/2 billion cores. It supports a
8number of ISAs including RISC-V with its P-Mesh cache coherence protocol and
9networks on chip. It is highly configurable in both core and uncore components.
10OpenPiton has been verified in both ASIC and multiple Xilinx FPGA prototypes
11running full-stack Debian linux.

Tianrui Wei2ef594d2021-07-01 12:54:19 +0800[diff] [blame]16Currently, OpenPiton implements RISC-V standard bootflow in the following steps
17mover.S -> u-boot-spl -> opensbi -> u-boot -> Linux
18This board supports S-mode u-boot as well as M-mode SPL

Tianrui Wei2ef594d2021-07-01 12:54:19 +0800[diff] [blame]75Put the generated fw_payload.bin into the /boot directory on the root filesystem,
76plug in the SD card, then flash the bitstream. Linux will boot automatically.
