To build and flash your LoPy for 868MHz regions:

$ cd esp32
$ make BOARD=LOPY TARGET=boot
$ make BOARD=LOPY LORA_BAND=USE_BAND_868 TARGET=app
$ make BOARD=LOPY LORA_BAND=USE_BAND_868 flash

or for 915MHz regions:

$ cd esp32
$ make BOARD=LOPY TARGET=boot
$ make BOARD=LOPY LORA_BAND=USE_BAND_915 TARGET=app
$ make BOARD=LOPY LORA_BAND=USE_BAND_915 flash

or the WiPy 2.0:

$ cd esp32
$ make BOARD=WIPY TARGET=boot
$ make BOARD=WIPY TARGET=app
$ make BOARD=WIPY flash

Make sure that your board is placed into programming mode, otherwise flahing will fail.
To do this, connect ``P2`` to ``GND`` and then reset the board.

Doesn't P2 refer to G23 on the extension board?

Yes. Regarding WiPy's pin out, it is the same.
I do not own an extension board, but it should also apply here.
See https://www.pycom.io/wp-content/uploads/2016/11/wipy_pinout.pdf .


For more recent information about the process of building and flashing, please refer to
the `README.md` file in the `esp32` folder.
