Wild! Linux running on RISC-V emulated in Scratch #RISCV #Linux #Scratch

In Scratch Projects, bilman66 posts using Scratch as a RISC-V emulator running the Linux 6.1.14 kernel:

A real build of the Linux 6.1.14 kernel running in pure scratch code!
This is done by running the Linux kernel on a RISC-V (rv32ima) emulator I wrote in Scratch, based off of Cnlohr’s mini-rv32ima emulator.

Use turbowarp for results that are actually usable.

To start the emulator (should be run in turbowarp), simply just press the green flag and load your ROM (or don’t to use the Linux kernel) then click the run button and wait for it to boot (takes around 40 seconds on my laptop). The Linux build comes with the usual programs like cat/echo and is fully capable of running shell scripts, but it also comes with a duktape (a JavaScript engine), as well as ed for text editing, and coremark for benchmarking

To use duktape, run “duktape {FILE_NAME}”. For testing, there is already a file called “fizzbuzz.js” that can be run In order to write to files you must use the “ed” text editor, for more information on ed and how to use it look here. Run “cat readme.txt” for some info!
