#68929 I am using ESP8266 to control Four 7 segment display. Initially, there were no problems during. But now suddenly, the board stops working all of a sudden. When i checked the GPIO 0's voltage is 2.0 Volts and my code is not getting executed. So, what may be the problem with GPIO 0?

I have a 100K pull-up resistor in GPIO 0, along with a 47K and a LED in parallel, I am using a dip switch to make GPIO 0 for flashing.
