I have the same problem - missing “Upload File System Image” option in PlatformIO Pallete (after clicking bottom “PIO Build”) there was allways option “Upload File System Image”, but after I reinstalled my MacOS 10.11 (because HDD fail), and fresh new install Atom + PlatformIO, this option is missing! Please help. The shortcut “alt+shift+cmd+f” don’t work! Only when run shell command “pio run -t uploadfs” this works and do everything correctly as always did the old “Upload File System Image” button…
SW: PlatformIO core 4.3.4 in Atom + platform ESP8266 actual version
