Errors flashing NodeMCU to ESP8266
问题 I've been having a bit of a rough time trying to flash the latest dev firmware. I've edited the question with a bunch of copy/paste examples from my cli and to clarify the steps I've taken so far. Here's what I've tried doing: I downloaded the 1.4.0 master and dev versions of firmware from the custom build service. I tried to flash the 1.4.0 master version with this command: python esptool.py --port /dev/ttyUSB0 write_flash -fm=dio -fs=32m 0x00000 ~/git/nodemcu- firmware/bin/nodemcu_integer_1
