Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Yes, you can do that with it too...
I was just avoiding doing it because it's a great way to brick your Pico (you'd then have to enter DFU to fix it) if something goes wrong :)
But if you created a Uint8Array with the first 16kB of the Espruino binary, then erased the page at
0x08000000and then wrote the array into that address, you should be sorted.but if you want to enter DFU with a Pico soldered down, there's another method too. If you look on the top of the board there's a small gold teardrop. That's BOOT0, so if you just short that to 3.3v while power is applied the board will enter DFU mode :)
