m0 feather express flashing CircuitPython
I am attempting to flash CircuitPython m0 feather express. I put the board into boot mode, two presses on the reset button the red LED comes on and the other LED turns green, I drop the ufc file into the featherboot drive. The red LED blinks a few times and everything goes dark. the boot drive disappears and nothing replaces it. I re flashed the boot loader and it seemed to work but no help.

Re: m0 feather express flashing CircuitPython
Just to check, What Circuit Python image file are you you loading?
It should be adafruit-circuitpython-feather_m0_express-2.2.0.uf2 from
https://github.com/adafruit/circuitpython/releases
Also what OS are you working from?

adafruit-circuitpython-feather_m0_express-2.2.0.uf2. I downloaded it Monday. I am working from my mac mini with the latest OSX.
I had no problems with my Gemma M0 with CircuitPython or Circuit Playground Express with MakeCode. Same cable

Re: m0 feather express flashing CircuitPython
hmmm - 2 suggestions:
1) just reboot the Mac - always worth a try ;-)
2) It is possible the File system has gotten corrupted - you can erase and restore it as shown in https://learn.adafruit.com/welcome-to-c ... ive-issues
go into Bootloader then
first load the "eraser" then reload the Circuitpython image
Good luck!

Re: m0 feather express flashing CircuitPython
That's to be expected! You are on the right track. When you use the erase file, it will remove everything on the board, and when you flash CircuitPython, that boot_out.txt file is all that is included. You will now need to load the library bundle and create your code.py file to start working with CircuitPython.
