General discussion • Re: RP2350 and Pico 2 released!

Yes, that's easy enough, what has to currently be done for an RP2040.

What I was hoping for was to have an RP2350 with no Flash, and be able to boot it with code uploaded over reasonable distances using serial at more common baud rates.

I would have ideally liked it to be the same as Mass Storage BOOTSEL mode so I could just stream a UF2 file to it, or by using 'picotool' with a serial rather than USB connection, but alas not.
On RP2040 this requires an external flash and can be bricked. On RP2350 you can put this bootloader in OTP, which does not require a second chip on the board, and can be made unbrickable by locking the OTP pages. That's quite a sizeable difference.

We considered making it UF2/PICOBOOT-compatible but wanted to keep the interface as simple as possible so that another microcontroller can just stuff a binary into it without dealing with more complex packetisation or error handling.
