#19571 Hello,
I'm following Tuan's instructions on loading the firmware on a ESP8266 (ESP-01 version) :

But when I run esptool.py, I get a connection error. Using miniterm, I see that my ESP8266 is booting up to

ets Jan 8 2013,rst cause:1, boot mode:(1,1)


I have another ESP8266 that boots up to boot mode:(1,0). Someone on the forum said the boot mode should be (1,7).

I'm sure I have D0 pin grounded, which is supposed to tell the ESP8266 to go into firmware load mode. My 3.3V power supply is pretty good, so it shouldn't be a power issue. Any other tips?
