Hi! Subject says it all: Plasma Stick 2040 w bricked after firmware 1.1.0 update Board was fine before update. Updated following instructions in the repo. uf2 file copes over but device does no reset. Tried firmware versions with and without file system. Thonny can connect, but shows no files …

I just flashed mine with, https://github.com/pimoroni/plasma/releases/download/v1.1.0/plasma_stick_2040_w-v1.1.0-micropython-with-filesystem.uf2 And I can connect to it from Thonny. No files shown though? I can run code on it from Thonny and save a main.py to it, that runs on a reset.

Thanks for that info. I used the same version of firmware and Thonny can connect but shows an empty file system even though I flashed with the file system version of the firmware. I can upload micropython files to it but when I try to run them they throw this error: MPY: soft reboot Board function…

This was my bad in two ways: 1) I thought the file system version installed the examples (it doesn’t) and 2) i tested with old examples and the plasma library has changed. After working through that, back in business. Thanks!

Ok, glad you got it sorted out. I was also expecting to see the examples. The file I test ran was my main.py that I had saved before re flashing my stick.

Hmm, I would have also expected examples. I’ve opened an issue on the repo to see if we can bring them back :)
