esp8266: Replace esptool by esptool.py
Created by: george-hopkins
As mentioned in nekromant/esp8266-frankenstein#14, esptool
can be replaced by esptool.py
.
This patch depends on the -o
option of the elf2image
command, which is not yet available if you use esp-open-sdk
. As soon as pfalcon/esp-open-sdk#13 is resolved, all users are able upgrade easily.
