You can use any of the firmware flashers other than arduino.

$ sudo pip install esptool
$ esptool.py --port /dev/ttyUSB0 write_flash 0x00000 image.elf-0x00000.bin 0x40000 image.elf-0x40000.bin

@UncleRus you also need to upload the mpfs file. I'm not sure what the syntax for that is, though.

Maybe...

$ sudo pip install esptool
$ esptool.py --port /dev/ttyUSB0 write_flash 0x00000 image.elf-0x00000.bin 0x40000 image.elf-0x40000.bin 0x10000 web/page.mpfs
