If you have connected other devices to GPIO pins, try removing them and see if esptool starts working.

Writing to Flash Fails Part Way Through If flashing fails with random errors part way through, retry with a lower baud rate. 76800 baud was one of the standard baud rates years ago, not sure why it is hardly supported any longer. ok, yuk, I just pulled out my macbook pro and had a play with 'screen'. if you set the baud to 76800 you get 9600 baud. set to 115k works, set to 76800 and it defaults back to 9600. no warnings whatsoever.

See if the program is crashing during early startup or outputting an error message. Serial Terminal Programs There are many serial terminal programs suitable. However, depending on your moduleboard, USB-UART convertor, cables, host OS, etc., the above baud rate may be too high and lead to errors. Try a more common 115200 baud rate instead in such cases.

When the esp8266 boots the baud rate is 74880, if you do not have your terminal set to 74880 the meaningful information it sends out comes out as garbage. 74880 is fast enough for most comms, and I now use it as my standard rate. Can we have 74880 supported by the Arduino IDE. Pretty Please. The baud rate is limited to 115200 when esptool.py establishes the initial connection, higher speeds are only used for data transfers. Most hardware configurations will work with -b 230400 , some with -b 460800 , -b 921600 andor -b 1500000 or higher. As a result, when the flashing offset address or the data are not 4096-byte aligned, more memory is erased than actually needed. Esptool will display information about which flash memory.
