ValueError:
Incompatible .mpy file
This error occurs when importing a module that is stored as a .mpy binary file that
was generated by a different version of CircuitPython than the one its being loaded
into. In particular, the mpy binary format changed between CircuitPython versions 6.x
and 7.x, 2.x and 3.x, and 1.x and 2.x.
So, for instance, if you upgraded to CircuitPython 7.x from 6.x you'll need to download
a newer version of the library that triggered the error on . All libraries are
import
available in the Adafruit bundle ().
CIRCUITPY Drive Issues
You may find that you can no longer save files to your CIRCUITPY drive. You may find
that your CIRCUITPY stops showing up in your file explorer, or shows up as NO_NAM
E. These are indicators that your filesystem has issues. When the CIRCUITPY disk is
not safely ejected before being reset by the button or being disconnected from USB,
it may corrupt the flash drive. It can happen on Windows, Mac or Linux, though it is
more common on Windows.
Be aware, if you have used Arduino to program your board, CircuitPython is no longer
able to provide the USB services. You will need to reload CircuitPython to resolve this
situation.
The easiest first step is to reload CircuitPython. Double-tap reset on the board so you
get a boardnameBOOT drive rather than a CIRCUITPY drive, and copy the latest
version of CircuitPython (.uf2) back to the board. This may restore CIRCUITPY
functionality.
If reloading CircuitPython does not resolve your issue, the next step is to try putting
the board into safe mode.
Safe Mode
Whether you've run into a situation where you can no longer edit your code.py on
your CIRCUITPY drive, your board has gotten into a state where CIRCUITPY is read-
only, or you have turned off the CIRCUITPY drive altogether, safe mode can help.
