Troubleshooting

If R2P2 hang up (sorry for a bug😓)

Plug off, wait 3 seconds, and plug in again. If it obviously hangs up again, please report it to us with the detail steps to reproduce the hang up.

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

NoMemoryError???

You will get NoMemoryError if you use R2P2 and IRB for a long time. Please reboot R2P2.

If a single script causes NoMemoryError, the script might be too large. Otherwise, you have hit a memory leak bug. Please report it to us with the script!

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
