I created a small tutorial explaining how to run NuttX RTOS on ESP32:

If you don't know about NuttX yet, this is the RTOS used on drones, used on Motorola Moto Z Snaps/Mods covers, used on Sony digital audio recorders, used on Samsung IoT devices and many other IoT devices from other vendors.

The WiFi support for ESP32 is not integrated yet (only Broadcom chips are supported by NuttX currently), but I'm sure that Espressif will help it happen
