Installation

Download the firmware:

http://micropython.org/download/esp32/

Non-SPIRAM firmware will work on any board, whereas SPIRAM enabled firmware will only work on boards with 4MiB of external pSRAM.
Firmware built with ESP-IDF v3.x has support for BLE, LAN and PPP.
Firmware built with ESP-IDF v4.x, has support for BLE, but no LAN or PPP.
If in doubt use v3.x.

Flashing the Firmware:

esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash
esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x1000 esp32-idf4-20191220-v1.12.bin
