To flash or erase your FeatherS2, you have to first put it into download mode. To do this, follow these steps:

esptool --chip esp32s2 --port COM(X) erase_flash
Now download the version of the firmware you would like to install from the options
below, then use the following command to program the firmware starting at address
0x1000, remembering to replace feathers2-micropython-firmware-version.bin with the
name of the firmware you just downloaded:
