Mongoose ESP8266 Wifi module flash error

I am getting error to flash mongoose os to esp8266 WIFI module it showing that less capacity of RAM . If its possible to Compress the file to Flash


You need an ESP8266 with at least 2MB of flash. Your module has only 1MB.

If it is possible with ESP866-01 Wifi module ?(1MB)

The ccm firmware needs OTA update, hence the requirement of a 2MB of flash module.

Using 2MB Flash we can do OTA update and AP ?Can you please Suggest 2MB Flash ESP8266 .
