Will the firmware update of Espruino Pico utilise the USB DFU function of the ROM Bootloader?
I noticed that the build environment is using http://dfu-util.sourceforge.net but im curious if the DFU function is only intended for the development phase?

Yes, DFU is only for development - there's a solder jumper on the back of the Pico that you can short out in order to use it though.

The Pico's going to use basically the same bootloader as is on the original Espruino Board. It enumerates as a USB COM port that accepts ST's USART bootloader protocol, so you can flash it from the Web IDE.
