The following files are firmware for the TinyS2.
Program your board using the esptool.py program, found here.
To flash or erase your TinyS2, you have to first put it into download mode. To do this, follow these steps:
Now the board is in download mode and the native USB will have enumerated as a serial device.
If you are putting MicroPython on your board for the first time then you should first erase the entire flash using:
esptool.py --chip esp32s2 --port /dev/ttyACM0 erase_flash
esptool.py --chip esp32s2 --port /dev/cu.usbmodem01 erase_flash
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 tinys2-micropython-firmware-version.bin
with the name of the
firmware you just downloaded:
esptool.py --chip esp32s2 --port /dev/ttyACM0 write_flash -z 0x1000 tinys2-micropython-firmware-version.bin
esptool.py --chip esp32s2 --port /dev/cu.usbmodem01 write_flash -z 0x1000 tinys2-micropython-firmware-version.bin
Change (X) to whatever COM port is being used by the board
esptool --chip esp32s2 --port COM(X) write_flash -z 0x1000 tinys2-micropython-firmware-version.bin
