## Flashing board ?
You need to maintain `SW2` while pressing `SW1` (reset) in order to set the ESP-12E in programing mode.

## FreeRTOS
It seems impossible to program the ESP-12E with RTOS from the Arduino IDE.
The SDK is maintained by Expressif and it svailable on:
https://github.com/espressif/ESP8266_RTOS_SDK
You will also find on this page the instructions to install the SDK
