esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header

Hi everyone!
I just trying to configure mi NODE mcu ESP8266 with an easy code just to blink a led, but I couldn't even upload the code due to an error about waiting for packet header.
I also install CH340G and FTD drivers, but the error remains the same.
I will appreciate if you guys could help me with this error.
I also try holding flash button for a couple of seconds when arduino is trying upload the program but it does not works.
And I also try flashing the NODEMCU by an external program but I never get the Mac adress for that.

Thank you very much!!
