Mike Perham documents installing Ruby 3.0.0-pre1 on a RISC-V simulator using QEMU.
QEMU comes with RISC-V built-in so there’s nothing else to be done (click that link if you want to see how to emulate a CPU with 1000s of lines of C code). You’ll need to download a RISC-V native boot disk, I found instructions and a nice Fedora Developer 20200108 image here. This developer image contains all the typical Linux developer tools, including GCC. I followed those directions except note we are using the Developer image, not the Minimal image. You log in with user:pwd “riscv:fedora_rocks!”.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
