I attached the ESP8266 pHAT to my Pi3 and on a fresh install of Jessie (same results if Jessie Light) follow the instructions to setup. When I run minicom, I get no response at all from the 8266, minicom seem sto lock up, the only way to close it is to close the session in putty.
If I follow the blog instruction and create the reset.py file, the 8266 seems to reset when it is executed. With no output in minicom, I’m afraid to try and update the firmware.
Thanks in advance.
