Hi,
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.
esptool.py v2.6-beta1
Serial port COM3
Connecting......................................_____

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.

thank You,
Hari

Hi,

I'm afraid if you are using an Arduino UNO, those do not use an ESP8266, or in fact any chip capable of running Espruino - so I think you're out of luck.
