I'm rather new to the ESP8266 world and got in contact via ITEAD Sonoff devices that use the ESP8266 and I managed to update the firmware there successfully, but one ITEAD Sonoff Touch just refuses to run the code.
The flashing process looks fine, but the only output I get via Serial Monitor (Arduino IDE 1.8.0) directly after [100%] upload is reached is this
oom 16
tail 8
chksum 0xef
csum 0xef
csum err
ets_main.c
No blinking LED or Serial Monitor output (with your code from post #2)
I'd appreciate any advice
Thanks!
