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

If you are putting MicroPython on your board for the first time then you should first erase the entire flash using:

Linux

esptool.py --chip esp32s2 --port /dev/ttyACM0 erase_flash

Mac

esptool.py --chip esp32s2 --port /dev/cu.usbmodem01 erase_flash

Windows

Change (X) to whatever COM port is being used by the board

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:

Linux

esptool.py --chip esp32s2 --port /dev/ttyACM0 write_flash -z 0x1000 feathers2-micropython-firmware-version.bin

Mac

esptool.py --chip esp32s2 --port /dev/cu.usbmodem01 write_flash -z 0x1000 feathers2-micropython-firmware-version.bin
