RISC-V Proxy Kernel

RISC-V Boot Loader (Lite)

About

This package contains the BBL-Lite, which is a minimal supervisor execution environment for RISC-V systems. It is designed to host the RISC-V Linux port.

Build Steps

We assume that the RISCV environment variable is set to the RISC-V tools install path, and that the riscv-gnu-toolchain package is installed.

$ mkdir build
$ cd build
$ ../configure --prefix=$RISCV --host=riscv64-unknown-elf --with-payload=linux-4.6.2/vmlinux
$ make

By default, the 64-bit (RV64) version of bbl is built. To build a 32-bit (RV32) version, supply a --enable-32bit flag to the configure command.

References

BBL-Lite is derived from riscv-pk.
