I have a NodeMCU ESP8266 ESP-12E and I tried uploading a file thru the SPIFFS. I am not sure why I see OTA instead of the SPIFFS?


Is there a configuration that I missed?

  • instructables.com/Using-ESP8266-SPIFFS/?amp_page=true not sure but check this . It may not help

  • maximum application size is less then 1 MB. so there is no other use for the rest of the flash then FS. for board you selected there is no predefined partitioning without OTA. what is your question?

SPIFFS (SPI Flash File System) is also know as FS(File system) . so What you are seeing as FS is basically SPIFFS .The OTA partition on esp8266 is compulsory so you cant get rid of it .

Hope this helps
