open BOOTSEL via software?

[LazaroFilm]

Hi, is there a way to load the BOOTSEL to a computer via code only? I have a pi pico with touchscreen and want to make a menu button that says Firmware update. When clicked it opens the folder on the desktop to load the new firmware in. This would streamline sending updates to clients. I don't have any physical buttons available on the device, only touchscreen

SOLVED:
calling this function anywhere in your code resets the board into Bootsel: reset_usb_boot(0, 0);
Then drag/drop a new *.uf2 firmware into the folder or disconnecting/reconnecting the USB restarts to the regular mode.

Check the Rp2040 docs in this repo. There's a reset to bootloader method which should do this.

Thanks! This put me on the right path to a solution!
