Trouble Shoot

If R2P2 hang up (sorry for a bug😓)

  • Plug off, wait 3 seconds, and plug in again

NoMethodError???

Picoruby is a small implementation for limited resources. It has less classes and methods than your usual CRuby. You can check API documentation here: https://picoruby.github.io/Array.html

If you app.rb doesn’t work as you wish and you get lost control of Raspi Pico

  • If you put /home/app.rb in your R2P2, it will run automatically at startup. But sometimes it may not work as you wish and you may get lost control of R2P2 shell.

  • At startup of R2P2, pressing “S” key will skip running the app.rb and R2P2 shell will be in control

When you’re stuck in a dead end, it may be ROM corruption

See R2P2 ROM corruption on RP2040/RP2350
