where does the TX and RX pin goes? What kind of device you are using to program the ESP? Give us some link of the USB programmer.
How do you put the ESP into programming mode? My ESP modules must have pin 0 pulled low during reset to go to program mode.
Here is my connection:D3(GPIO0) ----> ground.EN(enable) ---> VCC(3V3)A micro USB cable is used to program the MCU
Hey guys had the same Problem. For me the solution was to use a better USB cable that provides better power supply. cheers
