You can upload a firmware image without setting up a full Arduino dev. env. by using esptool (https://github.com/espressif/esptool - Install esptool with pip install esptool) and the folling command:

sudo esptool.py --chip esp8266 --port /dev/cu.usbserial-0001 --baud 921600 write_flash 0x0 ./firmware/ESPTOTP.ino.bin

The current / default firmware can be found in the /firmware folder of this repository.
