This repository houses a set of RISCV tools for the ariane core. It contains some small modifications to the official riscv-tools. Most importantly it does not contain openOCD.
Included tools:
- Spike, the ISA simulator
- riscv-tests, a battery of ISA-level tests
- riscv-pk, which contains
bbl
, a boot loader for Linux and similar OS kernels, andpk
, a proxy kernel that services system calls for a target-machine application by forwarding them to the host machine - riscv-fesvr, the host side of a simulation tether that services system calls on behalf of a target machine
- riscv-gnu-toolchain, the cross compilation toolchain for riscv targets
Requirements Ubuntu:
$ sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev libusb-1.0-0-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev device-tree-compiler pkg-config libexpat-dev
Requirements Fedora:
$ sudo dnf install autoconf automake @development-tools curl dtc libmpc-devel mpfr-devel gmp-devel libusb-devel gawk gcc-c++ bison flex texinfo gperf libtool patchutils bc zlib-devel expat-devel
Then install the tools with
$ git submodule update --init --recursive
$ export RISCV=/path/to/install/riscv/toolchain # default: ./install
$ make all
Add $RISCV/bin
to your path in order to later make use of the installed tools and permanently export $RISCV
.
Example for .bashrc
or .zshrc
:
export RISCV=/opt/riscv
export PATH=$PATH:$RISCV/bin
If you really need and want to debug on an FPGA/ASIC target the installation instructions are here.
