RISC-V isn’t as interesting as you think | Hacker News

It enables users to cross-compile a wide range of software for RISC-V and package them as file system images, or to be used with a package manager.

Instead of providing pre-compiled packages for a specific set of platforms, it is built around recipeswhich are scripts that describe how to fetch, cross-compile and deploy particular packages on different platforms, and adapt them to different usage scenarios.

Recipes also support features to describe hardwzre between targets, such as different boards, processor extensions or available peripherals. Yocto builds on the OpenEmbedded project, which is a collection of common recipes combined with a build tool bitbake that automatically tracks dependencies and parallelizes compilation tasks.

A typical Yocto build will consist of:. Running bitbake, which will download the sources for all packages including the cross-compile toolchainbuild everything while automatically managing the sysroots and produce:.

Yocto is an industrial-grade project, well-maintained and is an official part of the Linux Foundation. Many companies use OpenEmbedded to generate the Linux distributions powering their embedded devices, including SDKs for development boards such open hardware risc-v image the ZedBoard.

Some additional features include:. The large number of available packages makes Yocto a very good starting point for porting a full Linux distribution: many packages will build with the basic Yocto distribution without requiring any modifications at all -- all the work to do with managing sysroots, dependencies, etc.

We anticipate this problem to be resolved within the next weeks. This will automatically change harsware the build directory, which is where OpenEmbedded will do all open hardware risc-v image its work.

This directory contains a number of subdirectories and files; these are the most important ones:. Warning : This will download a large amount of data over the network and use up a significant amount of space on disk.

The local. Depending on the machine, the build process can take a very long time remember that this downloads and builds dozens of packages, including riscv-tools, riscv-qemu and riscv-linux. Note that bitbake is very efficient at utilizing highly parallel machines since it can spawn off many open hardware risc-v image in parallel. Once compilation has finished, you can run the resulting image from open hardware risc-v image build directory by calling:.

The qemuriscv imzge uses VirtIO for console, block devices and network. Note that this will cause an error when trying to run in QEMU, but it will work in the Spike simulator:. We would like to encourage you to submit pull requests opfn any packages that you port to RISC-V, so that we can grow riscv-poky into a complete Linux distribution.

The poky-riscv repository is a fork of the master branch from Yocto's main repository, poky. This is a development branch, and we are trying to track changes closely.

Currently, hardwre to poky. A good policy would be to work completely in the meta-riscv layer and move recipes outside the meta-riscv layer as RISC-V changes are upstreamed into other projects such as the Open hardware risc-v image kernel or GCC. Note that the old toolchain is not supported at this open hardware risc-v image and may cause compilation problems. Distributions : In addition to the default distrbiution poky-riscv with core-image-riscvit is also possible to build a minimal distribution using BusyBox, without SysV boot, package management and most applications.

To do this, set the distribution to poky-riscv-tiny in local.

The RISC-V ISA and some of the open cores allow (or even encourage) being bundled with proprietary hardware. Even locked-down, user-hostile hardware with patents and cryptographic protections is allowed. If you expect RISC-V to be the "Linux of hardware", think again. Mar 02,  · About RISC-V International.
