I tried loading custom firmware onto the pico. The firmware doesn't work. No problem, I can just load Espruino on it, which I successfully do. I load a sample .js file and run it, and no problem, it runs just fine.
However, about 40 minutes later, it stops working. During those 40 minutes I didn't touch the Pico at all and it wasn't hooked up to any power source.
