Unable to flash ESP
Posted: Sat Apr 29, 2017 2:10 pmHi
I have been trying to upload a sketch to my newly bought ESP 12-E without any luck
. I am using FTDI usb to ttl module. This is the way I am configuring my ESP during flashing :
GPIO 0,15 pulled down to gnd
GPIO 2, Reset pulled high to 3.3v through 10k resistors (External power supply used).
Tx --- Rx
Rx ---- Tx
Used 3.3 v external power supply to power the ESP
Connected FTDI's gnd to ESP's gnd.
This is the kind of error I get while uploading :
recieved : 18 expected : C0
recieved : 20 expected : C0
recieved : 1F expected : C0
espcommsync failed
Where am I going wrong?
Please help me out.........
