Program your board using the esptool.py program, found [here](https://github.com/espressif/esptool).
|
||
|
|
|
||
|
|
To flash or erase your TinyS2, you have to first put it into download mode.
|
||
|
|
To do this, follow these steps:
|
||
|
|
|
||
|
|
- Press and hold the [BOOT] button
|
||
|
|
- Press and release the [RESET] button
|
||
|
|
- Release the [BOOT] button
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
### Linux
|
||
|
|
```bash
|
||
|
|
esptool.py --chip esp32s2 --port /dev/ttyACM0 erase_flash
|
||
|
|
```
|
||
|
|
|
||
|
|
### Mac
|
||
|
|
```bash
|
||
|
|
esptool.py --chip esp32s2 --port /dev/cu.usbmodem01 erase_flash
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Windows
|
||
|
|
Change (X) to whatever COM port is being used by the board
|
||
|
|
```bash
|
||
|
|
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:
|
||
|
|
|
||
|
|
#### Linux
|
||
|
|
```bash
|
||
|
|
esptool.py --chip esp32s2 --port /dev/ttyACM0 write_flash -z 0x1000 tinys2-micropython-firmware-version.bin
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Mac
|
||
|
|
```bash
|
||
|
|
esptool.py --chip esp32s2 --port /dev/cu.usbmodem01 write_flash -z 0x1000 tinys2-micropython-firmware-version.bin
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Windows
|
||
|
|
Change (X) to whatever COM port is being used by the board
|
||
|
|
```bash
|
||
|
|
esptool --chip esp32s2 --port COM(X) write_flash -z 0x1000 tinys2-micropython-firmware-version.bin
|
||
|
|
```
