bbl-ucore is a porting of ucore_os_lab to RISC-V architecture. It's built on top of the Berkeley Boot Loader, bbl, a supervisor execution environment for tethered RISC-V systems.
You'll need a forked verison of riscv-tools to build the toolchain for RV32. Excute the following commands to get started quickly.
$ sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev
$ git clone https://github.com/ring00/riscv-tools.git
$ git submodule update --init --recursive
$ export RISCV=/path/to/install/riscv/toolchain
$ ./build-rv32g.shSee Installation Manual for details.
$ git clone https://github.com/ring00/bbl-ucore.git
$ git submodule update --init --recursiveTo build all projects at once, run the following commands
$ cd labcodes
$ ./gccbuildall.shDetailed documentation can be found here.
