3Openpiton RISC-V SoC
4====================
5
6OpenPiton RISC-V SoC
7--------------------
8OpenPiton is an open source, manycore processor and research platform. It is a
9tiled manycore framework scalable from one to 1/2 billion cores. It supports a
10number of ISAs including RISC-V with its P-Mesh cache coherence protocol and
11networks on chip. It is highly configurable in both core and uncore components.
12OpenPiton has been verified in both ASIC and multiple Xilinx FPGA prototypes
13running full-stack Debian linux.
14
15RISC-V Standard Bootflow
16-------------------------
17Currently, OpenPiton implements RISC-V standard bootflow in the following steps
18mover.S -> u-boot-spl -> opensbi -> u-boot -> Linux
19This board supports S-mode u-boot as well as M-mode SPL
20
21Building OpenPition
22---------------------
23If you'd like to build OpenPiton, please go to OpenPiton github repo
24(at https://github.com/PrincetonUniversity/openpiton) to build from the latest
25changes

703. Go to OpenSBI directory
714. make PLATFORM=fpga/openpiton FW_PAYLOAD_PATH=<path to u-boot-nodtb.bin>
72
73
74Using fw_payload.bin with linux
75-------------------------------
76Put the generated fw_payload.bin into the /boot directory on the root filesystem,
77plug in the SD card, then flash the bitstream. Linux will boot automatically.
78
79Booting
80-------
81Once you plugin the sdcard and power up, you should see the U-Boot prompt.
