Postby Hack-Mike » Tue Nov 17, 2020 4:55 pm

Hi guys,

I have an issue with ESP download tool v3.8.5, when I tried to erase o program the ESP32 the console print .....____.....____ endlessly, like photo below.

I'm using Win7, the FTDI drivers are installed correctly and ESP-IDF installed is 4.1.

Wiring connections between prog and ESP32 are:

vjtag <--> 3v3
GND <--> GND
TMS <--> gpio14
TDI <--> gpio12
TCK <--> gpio13
TDO <--> gpio15

hope in your help.

ESP download tool uses the serial port (TX/RX, plus IO0/Reset to get the device into download mode automatically), not JTAG.
