This repo provides a set of Dockerfiles that allows users to easily construct a software development environment of RISC-V architecture. Technically, the only dependency of this repo is Docker.
One is expected to learn Docker before she try to apply the tools in this repo. At least, one should setup a Docker environment, and then she can simply follow the steps in the Usage section.
Comments, suggestions, critics, and PRs are welcomed.
The core of the script is Makefile. Feel free to modify the variables on the top, especially IMAGE and container subnet settings.
$ make bootstrap
This generates a bootstrap image, which is not expected to be run, but just clone some repos and initial compilations. It takes hours to days depending on your network speed and storage quality, and occupies about 16G.
$ make update
This generates a basic image that is ready to be run. Still, it may take a long period of time, and the final images occupies 20+G space. You may always apply this command to sync the whole environment to the setting of freedom-u-sdk repo.
$ make private
You may reference and tweak the Dockerfile.private file to construct your working space. The current one is an example of my setting.
Note: Run this command for only ONCE.
$ make sim
Once you have a ready image, you can run this command which launches spike to run a RISC-V/Linux system with Busybox installed.
$ make run
You may assume that this command start a RISC-V/Linux Virtual Machine. Do make ssh to have other connections to the VM in new terminals. Once you have done some changes to the environment, you can apply make commit to save the status; or make off to turn off the VM without saving any changes.
In this VM, you have a set of toolchains in /home/riscv/bin, and related source trees in / directory.
Note that make run multiple times is not allowed.
