one too many binaries perhaps?

i usually use:

Code: Select allesptool.py --port /dev/ttyUSB0 write_flash \
    0x00000 eagle.app.v6.flash.bin \
    0x10000 eagle.app.v6.irom0text.bin \
    0x7c000 esp_init_data_default.bin \
    0x7e000 blank.bin


Where did you get these eagle binaries? All the Espressif site (Github actually) seems to have is the blank.bin. I also have the esp_init_data_default.bin from another zip file. It seems to assume you know how to compile the others from the various folders - but not on Windows?
