uf2 file

Post by femtopy » Mon Jun 07, 2021 5:04 am

Is there something wrong with the uf2 file? First, the filename does not match the one shown in the procedure. Second, I drag the uf2 file to the RPI-RP2, it seems to get copied and reboots but nothing happens. Don't see anything. If I unplug/replug the Pico while pressing the BOOTSEL buttonm the uf2 file is not there. What am I missing? Already tried 2 Pico boards with the same problem.

When you drag a uf2 file to the Pico it updates the firmware "automagically". The file does disappear. You can determine that the firmware has been updated by pressing ctrl-d at the REPL where you will see something like

Code: Select all

MicroPython v1.15 on 2021-04-29; Raspberry Pi Pico with RP2040
Type "help()" for more information.
>>> 
with a date matching the firmware build you have installed.

The Pico does not appear as a directory on the PC other than prior to a firmware upgrade.

Thanks. It looks like all I got to do is open a PuTTY.
