To reset the FiPy manually, press the button at the top once (it’s located right next to the LED light and it’s the only button on the FiPy module).
If the FiPy is connected to the expansion board you may also have a “Safe Boot” button in the corner. Sometimes it’s better to boot into “Safe mode” while trying to upload code. Simply hold the “Safe Boot” button while you press the reset button on the FiPy and release both at the same time. The LED light should flash orange and the device should do a “Safe Boot”. You can then continue to upload your code normally.
Hope this helps!
