Cannot get past this issue. Error message: Arduino: 1.8.9 (Mac OS X), Board: "Generic ESP8266 Module, 80 MHz, Flash, Disabled, ck, 26 MHz, 40MHz, DIO, 4M (1M SPIFFS), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Sketch uses 263416 bytes (25%) of program storage space. Maximum is 1044464 bytes. Global variables use 26848 bytes (32%) of dynamic memory, leaving 55072 bytes for local variables. Maximum is 81920 bytes. warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.
