Forum Index : Microcontroller and PC projects : Is it possible to ‘backup’ everything in a PicoMite into a single file

Probably a question for Peter, but will ask here hoping someone else may have some experience. I have an almost finished product that is based around a PicoMite (standard RP2350 firmware). Throughout development, I updated the firmware (typically to test Peter’s latest set of ‘goodies’), and OPTIONs were tweaked as I adjusted things. I also have a data file stored in the built-in flash drive that is used by my code. If I were to build another unit, then I would manually do the following: 1. Nuke Pico 2. Load standard RP2350 firmware (.uf2) 3. Configure OPTIONs manually (TeraTerm into Pico) 4. Load data-file into Pico (TeraTerm) 5. Save data file to drive A: 6. Load program code into Pico (TeraTerm) 7. RUN program….. Doing this as a one-off is fine, but the question is to ask if there is any way to take a ‘snapshot’ of everything in a configured Pico, generate a single file (.uf2?), and then simply load that into a ‘blank’ Pico so that everything is ‘pre-configured’. Hope this makes sense; and appreciate any help pointing me towards a solution…… |

Hi WhiteWizzard Some time ago, I wrote a Python tool („picom“) to backup and restore a picomite installation. It saves everything in a folder on the connected PC (not a single file, though). I use it for my projects, maybe you want to have a look. https://github.com/teuler/picom Best Thomas |

I haven't done it but Geoff certainly has and it is definitely doable to create a uf2 ready to go. |

Thanks Peter. I think I may have read something in his original Pico game console about this so will have a look when back home. Maybe Geoff can steer me on this if he sees this thread. |

We used to have a program here that allowed you to read out an RP2040 and use it to generate a uf2 file. I'm not sure if that works with a RP2350, though... Frank |

I got no errors in any of the install steps. Even though I did the pip install pyserial and even tried pip install serial, I get ModuleNotFoundError: No module named 'serial' I use Win 11. Footnote added 2026-04-25 05:27 by toml_12953 Ignore the above. I got out of PowerShell and back in then all the modules loaded properly. The list of serial ports only lists 5 although it finds 14. No big deal since the PicoCalc is always on COM5. I kept editing picom.py and not getting anything to work. Finally I saw that I have to change picom.toml to actually change the parameters. Everything works, now. picom.toml is an easy name for me to remember. Tom Lake |

I have not tried this (yet) but I read about picotool here: https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=18048 |

Many-Thanks for all the replies. Geoff - I will try following your clear instructions to generate an .uf2 file over the weekend; hopefully it will work for me here and generate what is needed. Thanks again. |

Geoff's "clear instructions" are exactly that. Worked first try. Worth including in the "Extra Documentation" folder. Edited 2026-04-25 16:30 by phil99 |
