Ardunino Nano RP2040 Connect - FS mode

[luci_codreanu]

Hello ,

I got 2 arduino nano connect . One of them after i failed to install micropython on it ,accidentally during installation i removed the usb cable. Now when i try to reinstall it says that the board is in FS mode.

I tried to program it using also arduino IDE . I tried to factory reset it also to reinstall bootloader . Nothing Works. When i connect it to my pc it is automatically detected like a mass storage . It is not neccesary to press the reset button for that .

I attached a picture. Can somebody tell me what to do to restore it to default.

Thank you.

Hi @luci_codreanu.

@luci_codreanu

I tried to factory reset it also to reinstall bootloader

By "factory reset", do you mean you performed the procedure described here?:

https://docs.arduino.cc/tutorials/nano-rp2040-connect/rp2040-01-technical-reference/#:~:text=factory-reset%20the%20board

you can choose to factory-reset the board by dragging the blink.ino.elf.uf2 file into the mass storage. You can download the file from the link below:

Yes ,what is described in your post . And also from Arduino IDE i tried firmware update...without success.

I tried hard to find an answer....what means this FS mode ? Can an admin help me ? How can i reset it ? What should i do ? It was a little bit expensive to throw it away just for this reason.

This board lack documentation. I think something is wrong with the bootloader...

Unfortunately I don't have any experience with Thonny. Arduino does provide a tool for installing the MicroPython firmware on compatible Arduino boards. I think it would be worth giving that a try:
