-  * WiFi. Use the script that builds firmware based on esp-hosted. It runs on core 0, linux runs on core 1, special linux IPC is used for communication. WiFi transport that uses linux IPC is added both to the firmware and to the linux kernel wifi driver. Not all wifi security options may be working, e.g. open and wpa2-psk are working and 802.11w is not.+  * WiFi.

   * Writing to FLASH and using ESP FLASH partition table. Driver based on linux IPC sends FLASH-related requests to the firmware. Default configuration has an etc partition that is flashed with /etc file system and mounted at boot time.
