OpenSBI Supported Platforms

OpenSBI currently supports the following virtual and hardware platforms:

  • Generic: Flattened device tree (FDT) based platform where platform specific functionality is provided based on the FDT passed by previous booting stage. More details on this platform can be found in the file generic.md.

  • QEMU RISC-V Virt Machine: Platform support for the QEMU virt virtual RISC-V machine. This virtual machine is intended for RISC-V software development and tests. More details on this platform can be found in the file qemu_virt.md.

  • SiFive FU540 SoC: Platform support for SiFive FU540 SoC used on the HiFive Unleashed board, as well as the sifive_u QEMU virtual RISC-V machine. More details on this platform can be found in the file sifive_fu540.md.

  • Kendryte K210 SoC: Platform support for the Kendryte K210 SoC used on boards such as the Kendryte KD233 or the Sipeed MAIX Dock.

  • Ariane FPGA SoC: Platform support for the Ariane FPGA SoC used on Genesys 2 board. More details on this platform can be found in the file fpga-ariane.md.

  • Andes AE350 SoC: Platform support for the Andes's SoC (AE350). More details on this platform can be found in the file andes-ae350.md.

  • Spike: Platform support for the Spike emulator. More details on this platform can be found in the file spike.md.

  • OpenPiton FPGA SoC: Platform support OpenPiton research platform based on ariane core. More details on this platform can be found in the file fpga-openpiton.md.

  • Shakti C-class SoC Platform: Platform support for Shakti C-class processor based SOCs. More details on this platform can be found in the file shakti_cclass.md.

The code for these supported platforms can be used as example to implement support for other platforms. The platform/template directory also provides template files for implementing support for a new platform. The object.mk, config.mk and platform.c template files provides enough comments to facilitate the implementation.
