I followed the steps provided in the steps to flash Espruino on ESP 8266 using esptool.py . I am unable to flash and i am getting fatal error continuously.
WARNING: Flash size arguments in megabits like '4m' are deprecated.
Please use the equivalent size '512KB'.
Megabit arguments may be removed in a future release.
Serial port COM3
A fatal error occurred: Failed to connect to Espressif device: Timed out waiting for packet header
I am trying from windows 10 PC connecting through COM port.
As any fyi - I successfully flashed espruino into nodemcu in past, but i am failing in arduino UNO model.
Please provide pointers to me. If it is not possible then please let me know, so that i won't try.
